MINI-BEAM SMU31 Universal Voltage Series Sensor 

Glass fiber sensors are an excellent option for sensing in tight or inaccessible areas. Fibers withstand vibration and shock and are immune to electrical noise. Glass fibers withstand high temperatures, extreme moisture, and corrosive materials. Glass fiber models are not recommended for applications requiring bending or repeated flexing of fibers (see plastic fiber models).

Plastic fiber sensors are an excellent option for sensing in tight or inaccessible areas. Fibers withstand vibration and shock and are immune to electrical noise. Plastic fibers function well at temperatures between -30º and +70ºC (-20º to +158ºF) and stand up to repeated flexing. Most are easy to shorten in the field, for custom installations. Plastic fiber models are not recommended for severe environments (see glass fiber models).

Integral 2 m (6.5 ft) unterminated cable models are listed.  To order the 9 m (30 ft) PVC cable model, add the suffix "W/30" to the cabled model number. For example, SMU31E W/30. 

## Overview 

MINI-BEAM Universal Voltage sensors (except opposed-mode emitters) have the following features: 

- Gain adjustment (1) 

- Light/dark operate selection (3) 

- • Signal strength indicator LED on the back of the sensor, protected behind a clear acrylic cover (2) 

To increase the gain, turn the 15-turn potentiometer clockwise. It is clutched at both ends of travel to avoid damage. A clicking sound may be heard and/or felt when attempting to adjust beyond either limit.

The Signal Strength indicator is Banner’s exclusive, patented AID (Alignment Indicating Device). Its pulse rate increases as the received light signal strength increases. This simplifies accurate alignment and gives a relative indication of sensing contrast. 

To select Light Operate, insert a small screwdriver into the slot on the select switch 

and turn it fully clockwise, until the tabs on the control touch the stop. To select Dark Operate, turn the select switch fully counterclockwise, until the tabs touch the opposite side of the stop. Carefully turn the Light/Dark Operate select switch to avoid damaging the small tabs on the switch. 

MINI-BEAM Universal Voltage Series sensors have no field-serviceable parts, other than replaceable lenses.

- Output type for all models (except emitters) is SPDT Electromechanical Relay 

## Installation and Alignment 

MINI-BEAM sensors perform most reliably if they are properly aligned and securely mounted. For maximum mechanical stability, mount MINI-BEAM sensors through 18 mm diameter holes by their threaded barrel (where available), or use a mounting bracket. A complete selection of mounting brackets is available. Visit www.bannerengineering.com or contact Banner Engineering for information on mounting www.bannerengineering.com or contact Banner Engineering for information on mounting  or contact Banner Engineering for information on mounting options. 

- Using line-of-sight, position the MINI-BEAM sensor to its emitter (opposed-mode sensing) or to its target (all other sensing modes). 

   - When using a retroreflective sensor, the target is the retroreflector (or retro target). 

   - For diffuse or convergent sensing modes, the target is the object to be detected.

2. Apply power to the sensor (and to the emitter, if using the opposed mode). 

3. Advance the 15-turn Gain control to maximum (clockwise end of rotation), using a small flat-blade screwdriver. The Gain control is clutched at both ends to avoid damage and will free-wheel when either endpoint is reached. If the MINI-BEAM sensor receives its light signal, then the red LED alignment indicator flashes at a rate proportional to the signal strength (faster = more signal). 

4. Move the sensor (or move the retro target, if applicable) up-down-right-left (including angular rotation) to find the center of the movement zone within which the LED indicator remains ON. 

5. Reduce the Gain setting by turning the Gain control. Reducing the Gain setting reduces the movement zone size and enables more precise alignment. 

6. Repeat the alignment motions after each Gain reduction. 

7. When optimum alignment is achieved, mount the sensor(s) (and the retro target, if applicable) solidly in that position. 

8. Increase the Gain to the maximum. 

9. Test the sensor by placing the object to be detected in the sensing position, and then removing it. 

- The Alignment Indicator LED should turn ON when the sensing beam is established (Light condition), and turn OFF when the beam is broken (Dark condition). 

## Opposed Mode Alignment 

In opposed-mode sensing, the sensor's emitter and receiver are housed in two separate units. The emitter is placed opposite the receiver so that the light beam goes directly from the emitter to the receiver. An object is detected when it breaks the working part of the light beam, known as the effective beam. 

In opposed sensing modes, light operate means the output is on when the beam is unblocked and dark operate means the output is on when the beam is blocked. 

Flooding occurs when a portion of the sensing beam passes around the object to be sensed. Burn-through occurs when a portion of the emitter’s light energy passes through a thin or translucent object, and is sensed by the receiver. 

To correct either problem, do one or more of the following to reduce the light energy: 

**==> picture [96 x 50] intentionally omitted <==**

**----- Start of picture text -----**<br>
Emitter<br>Receiver<br>Object<br>**----- End of picture text -----**<br>


- Reduce the Gain adjustment on the receiver 

- Add an aperture to one or both lenses (MINI-BEAM apertures, available from Banner, fit neatly inside the lens assembly) 

- Intentionally misalign the emitter and receiver 

## Retroreflective Mode Alignment 

A retroreflective sensor contains both the emitter and receiver elements. The effective beam 

is established between the emitter, the retroreflector, and the receiver. As with an opposedmode sensor, an object is sensed when it interrupts or "breaks" the effective beam. 

In retroreflective sensing modes, light operate means the output is on when the beam is unblocked and dark operate means the output is on when the beam is blocked. 

A highly reflective object may reflect enough light back to a retroreflective sensor to allow that object to slip through the beam, without being detected. This problem is called proxing, and the following methods may be used to correct it: 

- Position the sensor and retro target so the beam will not strike a shiny surface perpendicular to the sensor lens 

- Reduce the Gain adjustment 

- Add a polarizing filter (for model SMU315LV). 

## Diffuse Mode Alignment 

In diffuse-mode sensing, light emitted from the sensor strikes the surface of the object to be detected and is reflected back to the receiver, which is housed with the emitter. With a diffuse-mode sensor, the object is detected when it "makes" the beam, that is, the object reflects the sensor's transmitted light energy back to the sensor. 

**==> picture [40 x 182] intentionally omitted <==**

**----- Start of picture text -----**<br>
Retro LQ)<br>Target<br>Object<br>**----- End of picture text -----**<br>


In diffuse sensing modes, light operate means the output is on when the target is present and within the sensing range. Dark operate means the output is on when no target is detected. 

If the Alignment LED does not turn OFF when the object is removed from the beam, the sensor is probably detecting light reflected from some background object. To remedy this problem: 

- Reduce the reflectivity of the background by painting the surface(s) flat-black, scuffing any shiny surface, or drilling a large hole, directly opposite the diffuse sensor

MINI-BEAM SMU31 Universal Voltage Series Sensor 

- Move the sensor closer to the object to be detected and reduce the Gain adjustment. Rule of thumb for diffuse sensing: The distance to the nearest background object should be at least three times the sensing distance 

## Convergent Mode Alignment 

Convergent-mode sensors use a lens system to focus the emitter and receiver elements to an exact point in front of the sensor. Like diffuse-mode and divergent-mode sensors, convergent-mode sensors detect an object when that object completes or "makes" the light beam. This design produces a small, intense, and well-defined sensing area, at a fixed distance from the sensor lens. It is a very efficient use of reflective energy. 

In convergent sensing modes, light operate means the output is on when the object is present and within the sensing range. Dark operate means the output is on when no target is detected.

Reflectivity Low<br>Background<br>Object<br>**----- End of picture text -----**<br>


The sensing energy of a convergent mode sensor is concentrated at the specified focus point. Convergent mode sensors are less sensitive to background reflections than diffuse mode sensors. However, if background reflections are a problem: 

- Skew the sensor position at a 10° to 25° angle to eliminate direct reflections from shiny background surfaces 

- Reduce the reflectivity of the background by painting the surface(s) flat-black, scuffing any shiny surface, or drilling a large hole, directly opposite the sensor 

- Reduce the Gain adjustment

1. Install the O-ring (supplied with the fiber) on each fiber end, as shown in the drawing. 

2. While pressing the fiber ends firmly into the ports on the sensor front, slide the U-shaped retaining clip (supplied with the sensor) into the slot in the sensor's barrel, until it snaps into place. 

## Installing Plastic Fibers on a MINI-BEAM 

Follow these instructions to install plastic fibers into your sensor. MINI-BEAMS may have either a fiber gripper or a clamp screw. MINI-BEAM and ECONO-BEAM sensors for use with plastic fiber optic assemblies include sensors with the letters FP in their model number.

◦For models with a clamp screw: Loosen the clamp screw on the sensor face. 

3. Insert the plastic fibers. 

   - For models with a fiber gripper: Gently insert the prepared fiber ends into the ports as far as they will go. 

   - For models with a clamp screw: Align the fiber ends flush with the ends of the bushings as shown. Hold the bushings to the fibers and slide both into the sensor ports. Push the fiber an additional 1 inch through the bushing. 

4. Lock in the fibers. 

   - For models with a fiber gripper: Slide the fiber gripper back to lock, as shown in the figure. 

   - ◦ For models with a clamp screw: Tighten the clamp screw to secure the fibers. 

## Cut the Plastic Fiber 

- An unterminated plastic fiber is designed to be cut by the customer to the length required for the application. To facilitate cutting, a Banner model PFC-4 cutting device is supplied with this fiber. 

1. Locate the non-terminated end, and determine the length of fiber required for the application. 

2. Lift the top of the cutter to open the cutting ports. 

3. Insert the non-terminated end through one of the four large cutting ports on the PFC-4 cutter so that the excess fiber protrudes from the back of the cutter. 

4. Double-check the fiber length, and close the cutter until the fiber is cut. 

5. Gently wipe the cut ends of the fiber with a clean, dry cloth to remove any contamination. 

NOTE: Do not use solvents or abrasives on any exposed optical fiber. Do not use a cutting port more than once. The blade may tend to dull after one cut.

## Aperture Kits for MINI-BEAMs 

Opposed-mode MINI-BEAM sensors may be fitted with apertures that narrow or shape the effective beam of the sensor to more closely match the size or profile of the object to be sensed, for example, the use of “line” (or “slit”) apertures for sensing wire or thread. Each model contains 20 apertures.
