Banner Engineering SM91RSR VALU-BEAM® 912 Receiver Photoelectric Sensor, 3 m Sensing, Infrared Sensing Beam, 1 ms Response Time, Bi-Polar 1 NPN/1 PNP Output

Opposed mode sensors have higher excess gain than other models and therefore should be used whenever possible. The small size of these sensors makes them ideal for many conveyor applications and their small effective beam size (particularly of the ESR/RSR models) enables them to reliably detect relatively small objects. VALU-BEAM® opposed mode sensors have a visible red "tracer beam" which greatly simplifies sensor alignment. ESR/RSR models have a wide beam angle for very forgiving alignment within the 10 ft range. E/R models have a narrow beam spread and should be used when it is important to minimize optical "crosstalk" between adjacent emitter receiver pairs at close range in multiple sensor arrays.
