These sensors, which function as two-unit through-beam systems, combine a sender and receiver in a single housing. The distance between the sender and receiver is determined by the shape of the housing and is referred to as the fork width.

The emitted light, in the form of a precisely concentrated beam, and the high detection accuracy mean that even minute differences in light attenuation can be detected.
