## Models
|**Models**|**Specifications**|**Application**|**Description**|
|---|---|---|---|
|**SBD1**|**Range:**30 cm (12 in)
**Response:**1 ms on/off
**Beam:**infrared, 940 nm|Short Range, Fast
Response|The SBD1 model is a short range diffuse mode sensor with a relatively wide field of
view. It loses gain rapidly near the end of its range. As a result, its response to
background objects is suppressed. Use caution when applying any diffuse mode
sensor if background reflectivity exceeds the reflectivity of the object to be sensed.|
|**SBDL1**|**Range:**60 cm (24 in)
**Response:**1 ms on/off
**Beam:**infrared, 940 nm|Intermediate Range, Fast
Response|The SBDL1 model has a longer range than SBD1, but with less response to objects
passing the sensor at close range, and greater sensitivity to background objects.
Models SBD1 and SBDL1 are identical except for their upper cover (lens) assembly
(SBD1 uses UC-D; SBDLl uses UC-L).|
|**SBDX1**|**Range:**2 m (6 ft)
**Response:**10 ms on/off
**Beam:**infrared, 880 nm|Long Range, for Low-
Reflectivity Objects|The SBDX1 model is used for diffuse (proximity) mode applications when there is
no requirement for less than 10 ms response and where there are no background
objects to falsely return light. The SBX1 has a high excess gain for reliable detection
of most materials with low reflectivity which pass within 10 in (25 cm) of the sensor.|
|**SBDX1MD**|**Range:**60 cm (24 in)
**Response:**10 ms on/off
**Beam:**infrared, 880 nm|Wide Beam Angle for Clear
Objects|The SBDX1MD model has a wide beam angle for forgiving alignment to shiny
objects and provides detection of clear or translucent glass or plastics. It has high
excess gain at close range, with fast fall-off of gain near the maximum sensing
distance for optical suppression of reflective background. This model may be
created from model SBDX1 by substituting upper cover (lens) model UC-DMB.|
## Overview
A Banner MULTI-BEAM Sensor is a compact modular self-contained photoelectric switch consisting of three components: a scanner block, a power block, and a logic module.
The **scanner** block comprises the housing for the sensor and contains a complete modulated photoelectric amplifier, the emitter and receiver optoelements and lenses, and space for the other modules.
The **power** block module provides the interface between the scanner block and the external circuit. It contains a power supply for the MULTI-BEAM plus a switching device (except in emitter-only power blocks) to interface the sensor to the circuit to be controlled. The **logic** module interconnects the power block and scanner block both electrically and mechanically. It provides the desired timing logic function (if any) plus the ability to program the output for either light- or dark-operate.

MULTI-BEAM[®] 3- and 4-wire Diffuse Mode Scanner Blocks
The emitters of MULTI-BEAM opposed mode emitter/receiver pairs do not require a logic module. Emitter scanner blocks are supplied with a blade-pin to interconnect the scanner block and power block. Power block and logic modules are purchased separately. This modular design, with field-replaceable power block and logic modules, permits a large variety of sensor configurations, resulting in exactly the right sensor for any photoelectric application.
## Scanner Blocks
Diffuse mode MULTI-BEAMs combine emitter and receiver into one unit. Some of the emitted light, which is directed toward the object being sensed, returns to the receiver. Diffuse mode sensing is useful for presence sensing applications such as web break detection, ejected part detection, jam detection, open flap detection, and fill level detection of loosely packed products. Care must be taken to avoid sensing background objects: always verify that the distance to the nearest background object is at least three times the distance from the sensor to the object to be sensed. For example, if a product passes one inch from a diffuse sensor, the nearest background object should be at least three inches further away.
MULTI-BEAM 3- and 4-wire diffuse mode scanner blocks offer four different models. The high power model (those with 10 millisecond response time) offer the greatest optical sensing power of any industrial diffuse mode sensor.
The circuitry of all MULTI-BEAM components is encapsulated within rugged, corrosion-resistant PBT polyester housings that meet or exceed NEMA 1, 3, 12, and 13 ratings. MULTI-BEAM 3- and 4-wire diffuse mode scanner blocks include Banner's exclusive, patented Alignment Indicating Device (AID[™] ) system, which lights a top-mounted LED when the sensor sees its modulated light source and pulses at a rate proportional to the strength of the received light signal.
All MULTI-BEAM scanner blocks are totally solid-state for unlimited life.
_Figure 1. Functional Schematic_
## Installation and Alignment
Diffuse mode photoelectric sensing is useful for sensing the presence of almost any reflective object or material, and is used for sensing transparent or translucent materials when the distance from the sensor to the material is not fixed. A common example of this latter type of application is clear web-break detection when web flutter is uncontrolled.
Ranges for diffuse sensors are always specified using a white test card. Objects with less reflectivity produce shorter sensing ranges or less excess gain at a given range (see table below). Size may also be important: given two objects of the same reflectivity, a large object may return more light to the sensor than a smaller object.

Successful diffuse mode sensing depends upon adequate optical contrast between the object being sensed and the background behind the object. This means that the greater the difference between light reflected from the object and light reflected from the background, the more reliable diffuse mode sensing will be.
Most problems in diffuse mode sensing arise because of backgrounds which return as much, or nearly as much, light to the sensor as does the object to be sensed. In general, this problem is solved by using as dark a background as possible and by placing the background as far behind the object as possible. There is a general rule which states that the object-to-background distance should be at least three times the sensor-to-object distance.
Shiny materials usually require close control of the scanning angle to maximize the amount of reflected light actually returned to the sensor. The sensor should be mounted so that the sensing beam is exactly perpendicular to the object's surface.

Proper operation of diffuse mode sensors requires that they be mounted securely and aligned properly. Excessive movement or vibration could result in intermittent or false operation caused by loss of alignment to the object being sensed. Banner offers a variety of 2- and 3-axis mounting brackets for use with MULTI-BEAM sensors. See the Banner product catalog for bracket information.
## Banner's Alignment Indicating Device (AID[™] ) System
Banner's Alignment Indicating Device (AID) system 2 is an exclusive built-in feature that permits optimum alignment and continuous minoring of the photoelectric system. The red receiver LED indicator is on when the receiver sees the modulated light from the emitter and is off when the beam is broken. In addition, a low frequency pulse rate is superimposed on the LED indicator. When alignment is marginal, the pulse rate will be about once per second (indicating an excess gain of 1). As alignment is improved, the pulse rate increases, indicating increased excess gain. Optimum sensor alignment is indicated by the fastest pulse rate.
The AID feature also tells you when maintenance is necessary. Any pulse rate less than two per second indicates marginal performance; the unit, however, is still functioning properly. When the pulse rate slows to less than two per second, clean the lenses and check the alignment.
## Aligning the Sensor
The Alignment Indicating Device (AID) system LED on the top of the sensor is used in the following alignment procedure:
1. Begin with the sensor at the desired distance from the object and at the approximate position where it will be mounted. The background (behind the object to be detected) should be as far behind the object as possible, and of as dark a color as possible compared to the object to be detected. Ideally, the object should present its largest reflective surface to the sensor.
2. Apply power to the MULTI-BEAM power block (terminals #1 and #2; observe polarity on DC models).
3. With the object to be detected in place, adjust the position of the MULTI-BEAM relative to the object to produce the fastest LED alignment indicator pulse rate.
- If the LED appears to be on steadily, it is actually pulsing at a rate too fast to be seen. Being able to detect a change in the pulse rate when the sensor's position is changed will allow accurate alignment.

MULTI-BEAM[®] 3- and 4-wire Diffuse Mode Scanner Blocks
a) Slow the pulsing to a countable rate by reducing the sensitivity (counterclockwise rotation of the adjustment).
4. Turn the sensor's SENSITIVITY control to the fully clockwise position.
This is a 15-turn control, clutched at both ends.
5. Remove the object from the sensing position.
- a) If the alignment indicator LED turns off, check operation by alternately placing the object in position and removing it. The LED should follow the action by turning on when the object is present and turning off when the object is removed. If this occurs, then the alignment is complete.
**Note:** A steady on condition of the LED with the object present is the best situation, but this may not always be possible to achieve, especially if the object to be detected is of low reflectivity.
6. If the alignment indicator remains on when the object is removed, the MULTI-BEAM is receiving false light returned from a background surface.
- a) Reduce the sensitivity (counterclockwise rotation of the adjustment) until the alignment indicator LED turns off, plus two more full arms.
- b) Place the object in position and check that the alignment indicator LED turns on. (Repeat step #5, above.)
**Note:** If, in step #6, the LED does not turn on when the object is placed in position, the sensor is receiving as much or more light energy from the background as from the object. In this situation, consider the following alternatives:
- Move the sensor closer to the object and reduce sensitivity (not possible with model SBDL1 - see excess gain curve).
- Reduce background reflectivity by painting the background with a flat black paint, cutting a hole through it, scuffing its surface, etc.
- If the background surface is shiny, tilt the sensor (or the background surface) in any direction so that the beam is not perpendicular to the background surface.
- Evaluate other sensing methods, such as convergent beam or ultrasonic proximity sensing.
7. Secure the MULTI-BEAM in position and complete the wiring by connecting the load to the output circuit of the power block (terminal #3 and/or #4).
Refer to the hookup information for the power block in use.
8. Check operation of the load by alternately placing an object in front of the lens and then removing it.
9. Adjust the logic module timing (if any), as required.
**Note:** Logic modules (except models LM1, LM2, and LM10) include a light/dark operate programming jumper. Removing the jumper will invert the output state of the power block (from normally open to normally closed or vice versa).
**CAUTION:** Do not attempt to remove the programming jumper while power is applied to the MULTIBEAM!
## MULTI-BEAM Scanner Block Modifications
The following are common modifications to MULTI-BEAM 3- and 4-wire scanner blocks. They are not stocked, but are available on a quote basis.
**Zero Hysteresis Modification "MZ"** . Amplifier hysteresis may be removed from 3- and 4-wire scanner blocks when attempting to sense very small signal changes (contrasts less than 3). This modification is designated by adding suffix "MZ" (modified zero hysteresis). Verify all variables affecting the sensor's optical response remain constant before ordering the zero hysteresis modification.
**High Speed Modification "MHS"** . Scanner blocks with 1 millisecond response may be modified for 300 microsecond (0.3 ms) response. This modification is designated by adding suffix "MHS" to the scanner block model number (for example, SBD1MHS). The MHS modification reduces the available excess gain by about 50% and also decreases the sensor's immunity to some forms of electrical noise.
