Photoelectric fork sensors / angle sensors

As is the case with through-beam sensors transmitter and receiver are arranged face to face. Both components are permanent parts of a fork or an angle, i.e. they do not have to be aligned towards each other.
If an object enters the detection zone, the light beam is interrupted and a switching signal is generated. Optical fork and angle sensors use a particularly fine light beam and are thus suitable for the detection of tiny objects.
