With retro-reflective sensors, the transmitter and receiver are located in one housing and combined with a prismatic reflector. The reflector reflects the emitted light beam and if the light is interrupted by an object, the sensor switches. Retro-reflective photoelectric sensor consists of light projector and light receiver in one, has long effective distance range with the help of reflective board.
