With retro-reflective photoelectric sensors, or reflector sensors, the transmitter and receiver are located in one housing, just like with the diffuse proximity sensors. However, the retro-reflective sensor now always looks at a reflector, which is placed opposite of the sensor.

The output of the sensor becomes active as soon as an object moves inbetween the sensor and the reflector. Unlike with normal reflective sensors, polarized retro-reflective photoelectric sensors use special polarized filters so that the receiver accepts only light reflected by the reflector and not by another reflective object, such as the metallic paint of a car. Thus, it is possible to detect translucent and reflective objects as well.

A big advantage of these polarized retro-reflective sensors is that they are not susceptible to false detections. Do you want to delve further into the types of photoelectric retro-reflective sensors? Read more here!
