Retroreflective Photo Electric Sensor

Photo Sensor - Retroreflective  The PS-MR and LR Photo sensors have the emitter and receiver built into a single sensor head. They are powered by 24V DC. A plastic reflector is used to relay the light back from the transmitter to the receiver. When an object blocks the path of light the sensor is triggered.  The size of the beam of light can be specified. For general use, the standard spot would be selected. The larger size makes it possible to detect objects that are somewhat translucent or porous. As long as enough light is blocked the sensor can detect the the object. The standard beam sensor is good for larger objects. The large beam would not work as well for smaller objects, since the light could pass around the parts being detected and trigger the receiver.  The PS-MR sensor is designed with a microbeam of light. This makes it perfect for detecting small objects.  For small objects use the Microbeam sensors. The Micro Beam sensors have a small laser light that makes them eas
