A photoelectric sensor is equipment used to discover the distance, absence, or presence of an object by using a light transmitter, often infrared , and a photoelectric receiver. They are largely used in industrial manufacturing. There are three different useful types: opposed (through-beam), retro-reflective, and proximity-sensing (diffused).
