The Balluff through-beam sensors serve to detect objects reliably, regardless of surface, colour, material even with a heavy gloss finish. They consist of separate transmitter and receiver units that are attuned to each other. When an object interrupts the light beam, this causes a change in the output signal in the receiver. This sensor provides absolute reliability.
