DI-Soric OR21-PS-0.3T3, Retroreflective light barrier O-21, P\n: 212987

The transmitter and receiver are in one housing. The emitted light is reflected back by a reflector and evaluated in the retroreflective sensor. Polarization filters also allow the detection of reflecting objects. Retroreflective sensors make long ranges possible, with simple assembly and a high degree of system availability.
