- 1 To order the 9 m (30 ft) cable models, add the suffix “W/30” to the model number of any cabled sensor (e.g., SM31EL W/30). To order the 150 mm (6 inch) long pigtail cable with attached QD connector models, add the suffix “QDP” to the model number of any MINI-BEAM sensor (e.g., SM31ELQDP). Models with a QD connector require an accessory mating cable.
- 2 To order emitters and receivers with 0.3 millisecond on/off response, add the suffix “MHS” to the model numbers (e.g., SM31EMHS & SM31RMHS). This modification reduces sensing range (and excess gain).

MINI-BEAM SM31E/R Opposed Mode Sensors
## **Installation and Alignment**
Proper operation of the sensors requires they be mounted securely and aligned properly. Excessive movement or vibration can cause intermittent or false operation due to loss of alignment. For maximum mechanical stability, final-mount these sensors in 18-mm holes by their threaded barrels or use a mounting bracket .

A - “AID” Indicator LED lights when the sensor sees the reflection of its own modulated light and pulses at a rate proportional to the strength of the received light signal
B - 15 turn gain adjustment and light/dark operate switch
C - Gasketed acrylic cover
Regarding the light/dark operate switch:
- Turn switch fully clockwise for light operate (sensor outputs conduct when sensing light is received)
- Turn switch fully counterclockwise for dark operate (sensor outputs conduct when sensing light is not received)
_Figure 1. Receiver Adjustments_
1) Begin with the emitter mounted securely in place. For small-parts counting applications, stretch a string between the emitter and receiver lenses to ensure the sensing beam passes through the center of the sensing location. For less critical applications, the receiver may be initially positioned by line-of-sight placement. Mount the receiver, leaving a means for movement.
2) Apply power to the emitter and receiver, and advance the receiver’s 15-turn GAIN control to maximum (clockwise end of rotation). The GAIN control is clutched at both ends to avoid damage and will “free-wheel” when either endpoint is reached.
If the receiver is “seeing” the emitter’s light beam, the receiver alignment LED is on. Move the receiver up-downright-left (include angular rotation) to obtain the fastest receiver LED pulse rate. If a pulse is not observable (too fast to count), reduce the GAIN control (counterclockwise rotation) to obtain a countable pulse rate of one to five beats per second. Note: to aid alignment at short ranges, it may help to further reduce the strength of the light signal by temporarily masking the emitter and/or receiver lens with tape or a sheet of paper.

_Figure 2. Opposed Mode Alignment. Move the receiver to obtain the fastest LED pulse rate._
3) Repeat the alignment motions after each GAIN reduction. When you have found the receiver orientation that produces the fastest pulse rate, mount the receiver solidly in that position. Remove any masking material, and increase the receiver GAIN to maximum. Test the system by placing the object to be detected into the sensing position. The receiver LED indicator should go off. If it does not go off, the cause is probably either “flooding” or “burn-through”.
Flooding occurs when a portion of the effective beam passes around the object to be sensed and activates the receiver. Check that the object completely breaks the beam and that the beam is centered on the object. Add apertures, if necessary, to tailor the effective beam to the size or profile of the object being sensed. Burn-through refers to a portion of the emitter’s light energy passing through a thin or translucent object and activating the receiver. Try sensing at a reduced GAIN setting or consider an alternative sensing scheme.

The output type for all models is Bipolar NPN/PNP; load 150 mA max., each output.
## **Specifications**
## **Supply Voltage and Current**
10 to 30 V dc (10% maximum ripple) at less than 25 mA (exclusive of load)
## **Supply Protection Circuitry**
Protected against reverse polarity and transient voltages
## **Output Configuration**
Bipolar: One current sourcing (PNP) and one current sinking (NPN) open-collector transistor
## **Output Rating**
150 mA maximum each output at 25 °C, derated to 100 mA at 70 °C (derate ≈1 mA per °C)
Off-state leakage current: < 1 microamp
Output saturation voltage (PNP output): < 1 volt at 10 mA and < 2 volts at 150 mA
Output saturation voltage (NPN output): < 200 millivolts at 10 mA and < 1 volt at 150 mA
## **Output Protection Circuitry**
Protected against false pulse on power-up and continuous overload or short-circuit of outputs
## **Output Response Time**
Sensors will respond to either a “light” or a “dark” signal of 1 millisecond or longer duration, 500 Hz max. 0.3 millisecond response modification is available. See note below.
(100 millisecond delay on power-up; outputs do not conduct during this time.)
To order dc MINI-BEAMs with 0.3 millisecond on/off response, add the suffix “MHS” to the model numbers (e.g, SM31EMHS & SM31RMHS). This modification reduces sensing range (and excess gain).
## **Adjustments**
LIGHT/DARK OPERATE select switch, and 15-turn slotted brass screw GAIN (sensitivity) adjustment potentiometer (clutched at both ends of travel). Both controls are located on rear panel of sensor and protected by a gasketed, clear acrylic cover.
## **Indicators**
Exclusive, patented Alignment Indicating Device system (AID[™] , US patent #4356393) lights a rear-panel mounted red LED indicator whenever the sensor sees a “light” condition, with a superimposed pulse rate proportional to the light signal strength (the stronger the signal, the faster the pulse rate).
## **Construction**
Reinforced thermoplastic polyester housing, totally encapsulated, o- ring sealing, acrylic lenses, and stainless steel screws.
## **Environmental Rating**
Meets NEMA standards 1, 2, 3, 3S, 4, 4X, 6, 12, and 13; IEC IP67
## **Connections**
PVC-jacketed 4-conductor 2 m (6.5 ft) or 9 m (30 ft) cables, or 4-pin Euro-style quick disconnect (QD) fitting are available. QD cables are ordered separately.
## **Operating Temperature**
Temperature: −20 °C to +70 °C (−4 °F to +158 °F) Maximum relative humidity: 90% at 50 °C (non-condensing)
## **Application Notes**
The NPN (current sinking) output of dc MINI-BEAM sensors is directly compatible as an input to Banner logic modules, including all nonamplified MAXI-AMP and MICRO-AMP modules. MINI-BEAMs are TTL compatible.
