Functional principle

The SGS multi-beam safety light barrier is a
two-part system consisting of an active trans­mitter/receiver unit and a passive reflector
unit.

Models are available in 2-beam (500 mm res­olution), 3-beam (400 mm resolution) or 4­beam (300 mm and 400 mm resolution) ver­sions.

The detection range extends from 0.5 m to 6.5
m (8 m) and is reduced when using deflection
mirrors.

The SGS system can be configured for trip
output (automatic start/restart) or latch output
(manual start/restart).

If the light beams are interrupted, two redun­dant safety outputs (OSSDs) switch off.

The transceiver has a 7-segment diagnostic
indicator and individual LEDs for continuous
indication of the operating status, configura­tion and error conditions.
