Function description
The receiver receives the parallel light beam bundle generated by the transmitter. The light
beam bundle is enclosed by the illuminated target area. The lens on the receiver only de-
tects light that runs parallel to the optical axis. This guarantees stability against diffused
light.
The detection zone between transmitter and receiver is monitored and evaluated. The pro-
tected field is the cross section of the detection zone. It consists of several segments.

The shape and size of the protected field depend on the bending function and the machine-
dependent overrun. A reduced protected field is possible for box bending and/or back
gauge mode (see Protected field modes).

NOTICE
Do not use optical aids (e.g. lenses) to look at the light from the trans-
mitter.
This could damage the eye. If you do not use optical aids, there is no
danger to the eye.
