Through-beam sensors from Balluff are used for reliable object detection, regardless of surface, color, material - and even in the case of strong gloss. They consist of separate transmitter and receiver units that are aligned with one another. If an object interrupts the light beam, this causes a change in the output signal in the receiver. Absolutely reliable.
