Through Beam

The transmitter and the receiver are enclosed in separate housings with Through Beam Sensors. These are mounted so that the light beam emitted by the transmitter strikes the lens at the receiver. wenglor Through Beam Sensors are available with laser light, red light or infrared light. If the active light beam between the transmitter and the receiver is interrupted, the output is switched. Transmitters are equipped with a test input and can thus be checked for correct functioning. The controller works together with the light barriers SA250/EA250 and avoids a mutual influence of the sensors.
