Schmersal SLC/SLG445 safety light curtains and light grids

The SLC/SLG 445 series of safety light curtains and safety light grids are multifunctional devices. The functional diversity allows the individual application requirements to be more flexible, with the aim of achieving high productivity and safety.

The Multi-Scan function offers multiple evaluations of the protection zone. This increases the availability of the safety light curtain by suppressing temporary disturbances like flying burrs, steam clouds and flying insects, thus preventing false triggering.

The Mute function allows safe time-limited bridging of the safety light curtain for objects to be transported into or out of the danger zone. Up to four muting sensors can be connected easily via a field distributor with integrated cable, reducing effort and increasing the availability of the system.

Other features include fixed blanking, floating blanking, fixed blanking with movable edge region, double reset, contactor control (EDM), automatic mode, restart mode and beam coding. Set-up is simplified as selection and configuration of functions is made via a single push-button and the seven-segment display, so there is no need for software and a PC.

The compact construction in a rugged and weight-saving 28 x 23 mm profile allows the series to be used in tight installation situations. They are suitable for use in safety circuits up to Type 4 to EN 61496-1, PLe (EN 13849-1) or SIL3 (EN 62061).
