Photoelectric switch control by infrared radiation as an approach sensor, including a transmitter and receiver in it.

A retroreflective arrangement places the transmitter and receiver at the same location and uses a reflector to bounce the light beam back from the transmitter to the receiver.

An object is sensed when the beam is interrupted and fails to reach the receiver.
