Through-beam sensor, transmitter and receiver

Through-beam sensor, transmitter and receiver

Optical proximity sensors consist of two primary modules, i.e. a transmitter and a receiver. In the case of the through-beam sensor, these are housed in two separate housings. The receiver receives the red light emitted by the transmitter in the visible spectral range. If the emitted light path is interrupted by an object, the switching status of the electrical output changes. The object to be detected can reflect any amount of light, but must only let through a minimal amount. In the case of transparent, light-permeable objects, the sensitivity of the receiver can be set to a certain extent using a potentiometer.

The electrical connection is made with sockets for 4 mm safety plugs. The components are fastened to the profile plate by the Quick-Fix fastening system. The components can be moved in the direction of the groove.
