Safety Light Curtain Sensors

A photoelectric sensor, or photoeye, is a device used to detect the distance, absence, or presence of an object by using a light transmitter (often infrared) and a photoelectric receiver. They are used extensively in industrial manufacturing. There are three functional types: opposed (a.k.a. through-beam), retroreflective, and proximity-sensing.
