Functional principle

The SGS multi-beam safety light barrier with
integrated muting 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 connected sensors are monitored redun­dantly via the separate muting sensor connec­tion on the transceiver and automatically inter­rupt the protective function of the multi-beam
safety light barrier during the safe part of the
machine cycle.

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