## **MICRO-AMP[®] System** 

The Banner MICRO-AMP[® ] System is a family of miniature dc modulated photoelectric amplifiers and logic modules which offer the same sensing performance as larger, conventional modules.  They are the smallest photoelectric control modules ever built, and can fit easily into tight areas of machines or control panels.  Built around the concept of an I/O module, they are the perfect photoelectric control device for use with computers or programmable logic controllers (PLCs).  Multiple modules stack neatly on 1-inch (25mm) centers in PVC mounting track, taking only a fraction of the control panel space required by standard photoelectric modules. 

## **Dimension Drawing,  MICRO-AMP  Modules (except MPC3) with RS8 Wiring Socket** 

Model MA3 is a complete dc-powered modulated amplifier designed for use with Banner's SP100 Series of miniature remote sensors. Model MA3-4 is a higher-gain amplifier which is used with Banner's complement of high-performance modulated remote sensors.  Building-block style control logic may be added to a system with a selection of MICRO-AMP logic modules. 

Model MPC3 is similar to amplifier model MA3, except that it is specifically designed for PC board mounting in OEM sensing applications. 

MICRO-AMP modules may be mounted and wired using the optional model RS8 socket (shown in the drawing at right) or they may be mounted directly to a printed circuit board (see Accessories,  p. 20).

## **MICRO-AMP**[® ] **System MA3 and MA3P Modulated Amplifiers** 

Banner MICRO-AMP[® ] modules **MA3** and **MA3P** are **modulated amplifiers  designed for use with SP100 Series miniature remote sensors** .  Miniature photoelectric sensors have traditionally been used as _non-modulated_ devices with very limited response. MICRO-AMP amplifiers have a specially-engineered _modulated_ design which brings about a dramatic improvement in the optical performance of miniature remote sensors. MICRO-AMP  modules are powered by 10 to 30 volts dc, and feature the patented Banner Alignment Indicator Device (AID™) signal strength LED.  Sensor sensitivity is adjustable via a top-mounted GAIN potentiometer.  Model MA3 has complementary current sinking (NPN) outputs; model MA3P has complementary current sourcing (PNP) outputs. Circuitry is epoxy-encapsulated and enclosed in a tough molded  VALOX[® ] housing. Connections may be made to the MICRO-AMP via the optional RS8 socket/wiring base, or the module may be mounted directly to a printed circuit board (page 20). 

The small size and the slim ribbon-style connecting cable of SP100 Series sensors make it possible to use photoelectrics in many situations previously thought to be impractical or even impossible. 

## **MICRO-AMP**[® ] **Model MA3 Specifications** 

**SUPPLY VOLTAGE:** 10 to 30V dc at less than 20 milliamps (exclusive of load); 10% maximum ripple. 

**OUTPUT CONFIGURATION:** two open-collector NPN (current sinking) transistor (solid-state) switches; one normally open (light operate) and one normally closed (dark operate); 150 milliamps maximum, each output.  Saturation voltage less than 0.5V dc at 10 milliamp load.  Off-state leakage current less than 1 microamp. **RESPONSE SPEED:** 1 millisecond ON and OFF. **REPEATABILITY:** 0.3 millisecond. 

**SENSOR LEAD LENGTH:** 15 feet (4,5 m) maximum. 

**ADJUSTMENT:** GAIN adjustment (single-turn potentiometer; adjust with small flat-blade screwdriver).

## **DIFFUSE Mode Sensors** 

Models SP100D and SP100DB are general-purpose miniature diffuse sensors which detect the reflection of their own light from the surface of an object.  The SP100D is a right-angle design which is generally held in place using a #4 (3mm) screw.  The SP100DB ("B" = Barrel) is an in-line threaded barrel which typically mounts through a 3/8" (10mm) diameter hole using the lock nuts which are supplied.  The optical response characteristics of these two sensors are identical. 

## **CONVERGENT Mode Sensors** 

Models SP100C and CCF are ideally suited to applications where depth of field is critical.  The emitter and receiver are both directed at a point 0.1 inch (2,5mm) ahead of the front surface.  An aperture is included which, when attached, narrows the depth of field (see curves, below).  This is particularly useful when it is necessary to detect an object while ignoring another object or a surface just a fraction of an inch farther away.  The high excess gain at the focus allows detection of objects of low reflectivity.  The SP100C and CCF differ only in housing style.  Model SP100C is for general application.  Model SP100CCF is used where a narrow profile is important for mounting.

## **MICRO-AMP**[® ] **System MA3-4 and MA3-4P Modulated Amplifiers** 

Banner MICRO-AMP[® ] module **models MA3-4** and MA3-4P are modulated amplifiers designed for use with the popular family of Banner high-performance remote sensors.  When these modulated remote sensors are used with the MA3-4 or MA3-4P, their optical response is the same as when they are used with the larger MAXI-AMP™ CM Series modules. 

These modules are powered by 10 to 30 volts dc.  They feature the patented Banner Alignment Indicator Device (AID™) signal strength LED.  Sensor sensitivity is adjustable via a top-mounted GAIN potentiometer.  Circuitry is epoxy-encapsulated and protected by a tough molded VALOX[®  ] housing.  Connections may be made to these modules via the optional RS8 socket/wiring base, or the module may be mounted directly to a printed circuit board. 

The sensors which are used with these modules are totally encapsulated for durability and infinite life.  Wide beam angles eliminate alignment problems, and high optical gain permits reliable sensing under severe conditions.

**LR/PT200, 250, 300, and 400 opposed mode remote sensors** are identical electronically and optically, and differ only in their housings. All are totally epoxy-encapsulated and use hermetically sealed glass lenses to eliminate condensation inside the optical chamber.  These sensors may be washed down without damage.  Operating temperature is determined by the type of cable used (see specifications above).  All models have a wide beam angle for forgiving line-of-sight alignment. At the same time, the effective beam of each pair is only 1/8 inch, allowing small-profile resolution and reliable response to fast-moving objects. _LR models are emitters, and PT models are receivers._ 

**LR200 & PT200:** this is a right-angle design which mounts through a 7/16 inch (12mm) diameter hole, using the steel jam nut which is included.  This pair is used most commonly on small conveyors when it is desireable to run the cable directly down to a wireway. 

**LR250 & PT250:** these sensors feature a 1/4 inch (6,4mm) diameter smooth barrel design, and are usually held in place in a clearance hole with a small set-screw.  Optional mounting blocks (shown below) are available. Model  SMB250 holds the sensor in place with two setscrews.  The block is then mounted to a bracket (such as model SMB300), or directly to a machine frame with two #6 screws.  Block model SMB250C holds an LR & PT250 together to converge at approximately 1/2 inch ahead of the block.

**LR & PT300:** this is a miniature right-angle design which is mounted in place using two #4 screws.  This pair uses a very flexible, lowprofile 2-wire cable.  Despite their small size, the optical performance of the LR/PT300 is equal to the other remote sensor pairs. 

**LR400 & PT400:** the 3/8 inch (9,5mm) diameter threaded barrel design makes the LR/PT400 the most versatile and most popular remote opposed sensor pair.  They are easily mounted through clearance holes using the jam nuts which are supplied.  They may be used with optional L4 or L16 lenses for extended range and/or higher excess gain.  The addition of an L4 lens on both the LR and PT400 will increase their range from 8 feet to 40 feet and increase the excess gain at any distance by a factor of 25X.  A pair of L16 lenses will increase available excess gain by a factor of 250X.

Emitter-receiver pair **SP300EL/RL** are extremely rugged and are totally encapsulated in anodized aluminum housings.  The threaded hub at the cable exit allows for the use of flexible armored cable or protective PVC tubing with the addition of compression gland model CF7-16.  This pair uses collimating

The optics are such that even small threads or wires .005" (0,1mm) or greater in diameter may be detected when they pass within .25" (6mm) of the sensor's plastic lens. Due to its wide response pattern, the LP400WB  should not be used for precise positioning control, nor should it be mounted with its lens recessed into a hole.

**SP300D:** the SP300D is the diffuse mode version of the SP300L with the same rugged aluminum housing and totally encapsulated construction.  The glass lenses are hermetically sealed, which eliminates any possibility of condensation inside the lenses and allows operation in adverse environments like steam washdown and high vibration.  The SP300D may be mounted by its throughholes or with the SMB300 bracket, as shown below. 

**SP320D:** model SP320D is identical to the SP300D, except for its housing. The 320 is a miniature plastic package, designed to fit into very tight locations. It mounts using two #4 (3mm) screws.  The SP320D and the SP300D are excellent for nearly any presence sensing application. 

**Accessory bracket model SMB300** is designed for 2-axis universal mounting of sensor models SP300EL, SP300RL, SP300L, and SP300D. These sensors are affixed to the SMB300 with two #6 (3,5mm) screws. The bracket, in turn, mounts with two #10 (5mm) screws. 

In addition, as indicated by the dimension drawing, the SMB300 has a clearance slot for mounting LR400, PT400, and LP400WB barrel sensors.  LR & PT200 sensors may be mounted with the SMB300, using its 7/16-20 threaded hole and steel jam nut, which is supplied with the sensors.  LR250 and PT250 sensors may be used with the SMB300 when the SMB250 block is used.  Also, two SMB250 blocks may be attached to the SMB300 bracket and angled to mechanically converge an LR & PT250 sensor pair. 

The **SP1000V** is a convergent mode sensor that produces a very small 0.1 inch (2,5mm) diameter sensing image at a point exactly 3.8 inches (96mm) from its glass lenses.  As the excess gain curve illustrates, the SP1000V has a very sharp drop-off of gain beyond the focus point.  This feature makes it an excellent choice for detecting a small part which is only a fraction of an inch in front of another surface, such as parts on a conveyor (viewed from above).  It is also ideal for fill level detection and for precise positioning control, in lieu of opposed sensing.

## **Sensor Hookup Diagrams for MA3-4 MICRO-AMP Modules (continued on page** 

**10)** The following hookup diagrams include all of the remote sensors for use with the model MA3-4 modulated amplifier module.  It is important to note how the shield wire of a remote sensor is wired.  The shield wire is the uninsulated wire in each sensor cable.  Failure to connect the shield as shown may result in false operation of the amplifier.  When wiring emitters, it is good practice to connect the positive wire first.  LEDs are sensitive to application of the wrong voltage, and can easily be destroyed. 

## **Hookup of LR/PT200, 250, 300, and 400** 

NOTE: only one sensor may be connected to each MA3-4 amplifier. 

_NOTE:  Shield wires must be connected as shown to avoid cable crosstalk._

## **Hookup of SP320D** 

## _**IMPORTANT : Cable Splicing Information**_ 

Remote sensor cables may be run up to 30 feet (9m) away from the MA34 amplifier.  All sensor models are available from the factory with 30 feet of cable, installed as an option. 

When splicing additional cable to the standard 6-1/2 foot length, it is important to use a separate shielded cable for emitter and receiver wires. Combining emitter and receiver wires together in the same cable (even if the cable is shielded) will result in direct coupling of the emitter signal to the receiver leads. 

This is called "cable crosstalk" and will not allow full amplifier sensitivity setting without an amplifier "lock on" situation, which appears as a continuous LIGHT condition.  Banner offers 100 foot (30m) lengths of sensor extension cable (see below) which, if used for cable splicing, will minimize the chances for cable crosstalk. 

## **Accessories for High Performance Modulated Remote Sensors**

## **MICRO-AMP**[® ] **System MA4-2 One-Shot Logic Module** 

**MICRO-AMP**[® ] **module MA4-2** is a plug-in one-shot logic module with adjustable pulse length.  It is designed as a way to easily add one-shot timing to a MICRO-AMP system which uses an MA3 or MA3-4 amplifier.  It may also be used to add a one-shot timer to any current sinking DC device or to a system which offers a contact closure output. 

A low-going logic INPUT signal at pin #7 of the module activates a one-shot output at both pins #5 and #6, unless a low-going logic INHIBIT signal is present at pin #8 _when the input occurs._ Both NORMALLY OPEN (pin #6) and NORMALLY CLOSED (pin #5) outputs are available. Both are NPN open-collector (current sinking) transistors, each capable of switching up to 150 milliamps. 

Three pulse duration time ranges are selectable.  The .001 to .1 second range is standard, and .01 to 1 second and 1 to 15 second ranges are selected by connecting the appropriate module

**SUPPLY VOLTAGE:** 10 to 30V dc at less than 20 milliamps (exclusive of load); 10% maximum ripple. 

**INPUTS:** INPUT and INHIBIT both respond to a logic "low" signal (less than 2V dc).  A logic "high" is at least 6V dc or an open circuit.  Inputs must be capable of sinking at least 4 milliamps.  Inputs may be derived from limit switches or from dc sensors with NPN (current sinking) output transistors. 

**RESPONSE SPEED:** INPUT and INHIBIT will respond to a low signal or high signal of 1 millisecond duration or longer. **OUTPUT CONFIGURATION:** two open-collector NPN transistors with complementary outputs (one normally open, one normally closed). Maximum sinking current 150 milliamps, each output.  Saturation voltage less than 0.5V dc at 10 milliamps.  Off-state leakage current less than 1 microamp. **PULSE DURATION:** standard range is .001 to .1 second.  Programmable ranges are .01 to 1 second and 1 to 15 seconds. Select the .01 to 1 second range by connecting pin #2 to pin #3.  Select the 1 to 15 second range by connecting #1 to #3. **TIMING ADJUSTMENT:** single-turn timing potentiometer allows adjustment of pulse duration within the selected range (use small flatbladed screwdriver). **INDICATOR:** red LED indicator on the top of the module lights whenever the N/O output is conducting (i.e. when the N/O output is closed and the N/C output is open). 

**CONSTRUCTION:** totally encapsulated plug-in package with molded VALOX[® ] housing.  Gold-flashed connection pins. 

**OPERATING TEMPERATURE:** 0 to 70 degrees C (32 to 158 degrees F). 

## **Functional Schematic, MA4-2 ONE-SHOT Module** 

**Hookup Diagram, MA4-2 ONE-SHOT Module** 

There are two types of basic "one-shots": RETRIGGERABLE and NONRETRIGGERABLE.  The output pulse timing of a retriggerable one-shot is restarted with the reoccurance of every input.  The output will remain "on" as long as the time between consecutive inputs is shorter than the one-shot pulse time (see timing diagram, below).

A non-retriggerable one-shot timer must complete a pulse before it will accept any new input signals.  Non-retriggerable one-shots sometimes offer an advantage in indexing or registration control applications where multiple input signals are possible during advance of the product.  The MA4-2 may be programmed for the non-retriggerable mode by connecting pin #6 to pin #8.

## **MICRO-AMP**[® ] **System MA4G 4-input Gate Logic Module** 

**MICRO-AMP**[® ] **module MA4G** is a 10 to 30V dc, plug-in, 4-input logic gate module. It offers three selectable logic modes: "AND", "NOR", and "X-NOR" (exclusive "NOR").  In the AND gate mode, the output(s) will change state when all four inputs are low simultaneously.  The NOR logic mode requires that all four inputs be high at the same time for the output(s) to change state.  The output(s) will change state in the X-NOR mode when all four inputs are simultaneously _either_ high _or_ low.  The MA4G may be used as a 2, 3 or 4-input gate.  Unused inputs are simply tied low (to pin #3) or left unconnected (high), depending upon the logic mode in use. 

The MA4G directly accepts the outputs of other MICRO-AMP modules plus the NPN (current sinking) output of self-contained dc sensors. 

## **MICRO-AMP MA4G Specifications** 

**SUPPLY VOLTAGE:** 10 to 30V dc at less than 20 milliamps (exclusive of load); 10% maximum ripple. 

**INPUTS:** INPUT and INHIBIT both respond to a logic "low" signal (less than 2V dc).  A logic "high" is at least 6V dc or an open circuit. Inputs must be capable of sinking at least 4 milliamps.  Inputs may be derived from limit switches or from dc sensors with NPN (current sinking) output transistors. 

**RESPONSE SPEED:** all  INPUTS will respond to a low signal or high signal of 1 millisecond duration or longer. 

**OUTPUT CONFIGURATION:** two open-collector NPN transistors with complementary outputs (one normally open, one normally closed).  Maximum sinking current 150 milliamps, each output. 

Saturation voltage less than 0.5V dc at 10 milliamps.  Off-state leakage current less than 1 microamp. 

**SELECTOR SWITCH:** single-turn potentiometer selects logic mode.  Fully clockwise = NOR mode; fully counterclockwise = AND mode; midpoint = X-NOR mode. 

**INDICATOR:** red LED indicator on the top of the module lights whenever the N/O output is conducting. 

**CONSTRUCTION:** totally encapsulated plug-in package with molded VALOX[®  ] housing.  Gold-flashed connection pins.

## **Truth Table** 

This table lists the various input states and their corresponding outputs available in each logic mode.  The key to reading the table is given below.  Logic statements in the table read down the columns.  For example, in the first column, if the selector control is at "AND" and all four inputs are logic low, the MA4G's N/O output is low,   the N/C output is high, and the LED indicator is "on". 

## **Truth Table Key** 

H = logic HIGH L = logic LOW X = either HIGH or LOW (does not matter) 

- **"AND":** all inputs low energizes N/O output. Any input(s) high energizes N/C output. 

- **"NOR":** all inputs high energizes N/O output. Any input(s) low energizes N/C output. 

- **"X-NOR"** ("exclusive NOR"): All inputs the same energizes N/O output. All inputs not the same energizes N/C output.

## **MICRO-AMP**[® ] **System MA4L Latch Logic Module** 

**MICRO-AMP**[® ] **model MA4L** offers two latching logic modes.  It can be latched and unlatched with low-going signals to its SET and RESET inputs.  It also will function as an edge-triggered "D" flip-flop latch when signals are presented to its INPUT pin. The edge-triggered latch may be interrogated with a second signal at the INHIBIT or the RESET pin.  In this mode, the MA4L is very useful in inspection/rejection applications.  The MA4L may also be wired for alternate-action divide-by-two logic (see logic diagram, below). 

The MA4L directly accepts the outputs of other Banner MICRO-AMP modules plus the NPN (current sinking) output of self-contained dc sensors.

## **MICRO-AMP**[® ] **System MA5 Delay Logic Module** 

**MICRO-AMP**[® ] **model MA5** is a plug-in delay logic module with adjustable delay timing.  It is designed as a way to easily add an ON DELAY or an OFF DELAY timer to a MICRO-AMP system which uses an MA3 or MA3-4 amplifier.  It may also be used to add a delay timer to any current sinking dc device or to a system which offers a contact closure output. 

A low-going logic INPUT signal at pin #7 of the module activates an ON DELAY timer.  If the signal remains longer than the set ON DELAY time, the output at both pins #5 and #6 will change state.  If pin #8 is connected to pin #3, the MA5 is converted to an OFF DELAY timer.  In the OFF DELAY mode, an output will occur immediately when an input signal appears at pin #7, and the output will remain "on" after the input is removed for the OFF DELAY time period. 

The MA5 may be programmed to respond to a high-going input signal by connecting pin #1 to pin #3.  Both NORMALLY OPEN (pin #6) and NORMALLY CLOSED (pin #5) outputs are available (simultaneously).  Both outputs are NPN opencollector (current sinking) transistors, each capable of switching up to 150 milliamps. 

Two delay time ranges are selectable.  The .01 to 1 second range is standard, and a 1 to 15 second range may be programmed by connecting pin #2 to pin #3.  A potentiometer allows fine adjustment within each time range. 

The MA5 may be mounted and wired using the optional RS8 socket, or it may be wired into a printed circuit board either directly or by using the model RS8K PC board socket.

## **MICRO-AMP**[® ] **System MPC3 Miniature Modulated Amplifier for direct PC-board mounting** 

**Model MPC3** is a modulated LED photoelectric amplifier which utilizes custom CMOS integrated circuitry.  It contains all the circuitry necessary to modulate nearly any LightEmitting Diode (LED) and to amplify and demodulate the light received by a phototransistor.  The outputs are conventional buffered complementary CMOS gates. 

The MPC3 is designed to work with the Banner SP100 series miniature modulated remote sensors.  However, it may be used with nearly any LED and phototransistor pair, as supplied by most major semiconductor manufacturers.  The small size and low cost of the MPC3 permit its use in OEM equipment where conventional photoelectric controls are not justified, or where non-modulated sensors are now being used.  Typical OEM applications include duplicating machines, semiconductor processing equipment, label sensors, vending machines, vibratory feeder controls, robotic sensors, and automatic testing equipment. 

The MPC3 also contains the patented Banner "AID™" (Alignment Indicator Device) circuitry, which shows the strength of the received signal in addition to indicating the state of the outputs.  This feature permits easy setup and alignment of the sensors, and also provides a means for the ultimate user of the equipment to monitor its performance without test instruments.  An LED indicator is added (externally) to utilize the AID circuitry. Amplifier sensitivity is adjusted with an external potentiometer or fixed resistor.  Amplifier response speed is set at 10 milliseconds.  An optional frequency control resistor (Rf) may be used for faster amplifier response. 

The circuitry of the MPC3 is totally encapsulated in a high-impact molded polystyrene housing.  It is designed for mounting directly to a printed circuit board.  A set of eight closed-back pin jacks is supplied to allow the MPC3 to plug into the PC board.  A batterypowered demonstration board, model MPC3-DB, is available for evaluation of the MPC3.

## **MICRO-AMP**[® ] **MPC3 Specifications** 

**SUPPLY VOLTAGE:** 5V dc ± 10% at less than 20 milliamps; 100 millivolts maximum ripple.  Voltage must not exceed 6V dc, or be connected in reverse polarity.  Install a 0.1 microfarad capacitor as close as possible to the supply pins of the MPC3 (across pins #1 and #3) if voltage transients are anticipated. 

**OUTPUT CONFIGURATION:** the outputs at pins #7 and #8 are conventional CMOS buffered gates.  The output at pin #7 is high in the DARK condition and low in the LIGHT condition.  The output at pin #8 is low in the DARK condition and high in the LIGHT condition. Each output will source or sink several milliamps. 

**CIRCUIT PROTECTION:** outputs are short-circuit protected. They may be shorted to either the positive or negative supply line without damage.  The emitter output at pin #5 is internally currentlimited, and may be grounded indefinitely.  The "AID" output at pin #6 is internally current-limited, and may be connected to the positive supply indefinitely. 

**SENSITIVITY ADJUSTMENT:** the value of the sensitivity adjustment potentiometer, or of the fixed resistor if sensitivity adjustment is not anticipated, is 2,000 ohms (2k Ω ).  This is the optimum value for Banner sensors and for most phototransistors of other manufacturers. In situations where very high gain photodarlingtons or very low gain phototransistors or photodiodes are being used, Banner can help determine the best value. 

**FREQUENCY ADJUSTMENT:** the response time of the circuit is 

10 milliseconds or 4 oscillator pulses.  Since the demodulator is digital, faster response times are possible by simply increasing the frequency of the emitter oscillator.  This is done by installing a resistor ("Rf" in the hookup diagram) from pin #2 to the positive supply (pin #1).  The value of the resistor is best determined empirically, by observing the signal at pin #5 (with respect to ground) on an oscilloscope.  The response time of the MPC3 is equal to the time required for four pulses, and the repeatability of the response time is the time for one pulse.  The approximate value of Rf is 390k Ω for 5 millisecond response, and 39k Ω for 1 millisecond response. 

An internal emitter oscillator generates 30 microsecond pulses at a rate of about 400Hz.  When the frequency of the emitter oscillator is increased, the automatic emitter power control reduces the magnitude of the pulse current to the emitter so that it will not be damaged by the increased duty cycle.  As a result, the excess gain (and the range) of the sensors will automatically be reduced.  For this reason, the MPC3 should be operated at the slowest frequency (response time) that is consistent with the application requirements. 

**INDICATOR:** a constant current output is provided at pin #6 for a customer-supplied indicator LED.  This current is held to only a few milliamps in order to minimize power supply requirements.  If the LED that is selected does not appear bright enough, Banner can suggest or supply high-brightness indicators. 

**CONSTRUCTION:** totally encapsulated circuitry in molded highimpact polystyrene housing.   Closed-end jacks for PC plug-in mounting are included.

-40 to 70 degrees C (-40 to 158 degrees F).

## **Hookup Diagram, MICRO-AMP MPC3** 

**Circuit Description** The functional schematic shows the MPC3 powered by 5V dc at pins #1 and #3.  An internal emitter oscillator generates 30 microsecond pulses at a rate of approximately 400Hz, which are fed to the emitter at pin #5.  These emitter current pulses are controlled automatically by a patented* power-limiting circuit that adjusts to the emitter and to the frequency in use. 

The phototransistor receives the light pulses from the LED, either directly or by reflection from an object, and sends them to the input (pin #4) via the sensitivity adjustment resistor (or potentiometer).  These low-level signals are amplified, separated from the emitted light, and then detected by the threshold detector.  The resultant logiclevel pulses are then gated synchronously with the oscillator output (to eliminate noise and interference) and demodulated.  The demodulated output is then buffered and inverted, and brought to the output pins #7 and #8.  In addition, a small amount of hysteresis is fed back to the threshold detector to assure clean, bounce free output switching.  The amplified signal is also fed through a negative peak detector and to a voltage-controlled oscillator whose output frequency is directly proportional to signal strength.  This is the patented** Banner "AID™" feature which flashes the LED indicator at a rate which is proportional to the strength of the received light signal (excess gain).

## **Model MPC3-DB Demo Board** 

**The MPC3-DB** is a battery-powered demonstration/testing board which is available to help in evaluating the MPC3 and its sensor(s). The demo board includes a plug-in MPC3 and indicator LEDs for both outputs, plus the "AID™" indicator, a sensitivity potentiometer, and a 4-pin terminal strip to which the LED and receiver phototransistor may be connected. 

The MPC3-DB is powered by 3 "AA" penlight batteries.  (Yes, batteries _are_ included!!!)  This is a very simple and inexpensive way to become familiar with the characteristics of the MPC3, and to evaluate the sensors to be used with the MPC3.

## **MICRO-AMP**[® ] **System SP100FF Fixed-field Sensor** 

- **Optical design ensures an exact range limit, regardless of the surface reflectivity of the objects to be sensed** 

- **Powerful infrared light source and modulated amplification provide reliable sensing of objects with low surface reflectivity** 

- **Sensor response to background objects is completely suppressed** 

- 

   - **Miniature size fits easily into tight areas of machines** 

- **Works with special versions of Banner's MICRO-AMP[®] series of modulated amplifiers** 

**Model SP100FF** is a fixed-field convergent mode sensor that detects objects directly by reflection of light from the object's surface.  The light is sensed at two receive points and compared to define a precise limit to the maximum sensing range.  Objects in the background are ignored, regardless of their surface reflectivity. 

## **Conceptual Drawing** 

This sensing response feature makes the SP100FF an ideal choice for detecting a part or a surface that is only a small fraction of an inch in front of another surface. The SP100FF is highly reliable for semiconductor wafer sensing.  Wafers of all reflectivities are sensed without mechanical or system sensitivity adjustment. Other applications include cut-to-length control, double-thickness detection, and precision edgeguiding.  The SP100FF is an excellent choice for precise position control (e.g. as a robotic end effector). 

The SP100FF works in conjunction with Banner MICRO-AMP modulated amplifier model MA3A or MPC3A.  Model MA3A is powered by +10 to 30V dc and uses a model RS8 socket.  Model MPC3A is powered by +5V dc and is designed for mounting directly onto PC boards. 

With a typical excess gain of 100X at the peak signal point (referenced to a 90% reflectance white test card), the SP100FF has enough optical energy to reliably sense material of very low reflectivity such as nitride-coated semiconductor wafers.  The typical peak signal point is 0.12 inch from the sensor face.  Excess gain falls off sharply beyond the peak signal point (see excess gain curve, below). 

## **Theory of Operation** 

The SP100FF uses two photoelements that operate with the modulated amplifier in a differential mode.  The photoelements are mechanically convergent with the LED light source at two different distances from the sensor face.  The inner photoelement (R1) produces a positive-going pulse which turns the output of the amplifier "on".  The outer photoelement (R2) produces a negative-going pulse that works to turn the amplifier "off". 

## **Excess Gain Curve** 

A target is sensed whenever the amount of light reaching receiver R1 is equal to or greater than the amount of light "seen" by R2.  The output of the amplifier is cut off as soon as the amount of light at R2 becomes greater than at R1.   The location of this "crossover point" is dictated by the geometry of the optoelement configuration, and remains the same regardless of the target's reflectivity. 

Reflections even from highly-polished mirror-like surfaces are ignored if the reflections originate from beyond the crossover point.  Modulated LED design offers very high excess gain at the convergent point of R1 (see excess gain curve). As a result, even objects of very low reflectivity may be sensed. 

The rapid fall-off in signal strength over a very short distance (as seen in the excess gain curve) accounts for the highly repeatable distance-sensing accuracy of the SP100FF, independent of target surface reflectivity.
