Reflex Mode (One-Way System)
In reflex mode (one-way system), the transmitter and receiver are in one housing. The light from the transmitter is reflect-
ed back to the receiver by a reflector. The switching function is triggered when the light beam is interrupted.

2.2.3
Reflex Mode (Two-Way System)
In reflex mode (two-way system), the transmitter and receiver of the one-way light barrier are housed in physically sep-
arate fiber-optic heads. The transmitter (S) beams light onto the object to be detected and the object reflects the light in
the direction of the receiver. In this context, the surface structure or presence of an object can be detected, for example.
