Schmersal SLC440COM safety light curtains and SLG440COM safety light grids

Schmersal’s SLC440COM Series safety light curtains and SLG440COM Series safety light grids are an economical, compact solution that are said to offer the highest protection for the user, and incorporate highly visible status signalling in a rugged housing.

The series safety light curtains are available with resolutions of 14, 30 or 35 mm and protection field heights between 330 and 1770 mm, and are also available as safety light grids (SLG440COM) with two, three or four beams for perimeter guarding. Both series are suited for use in safety circuits up to PLe (EN 13849) or SIL3 (IEC 61508). The profile length corresponds to the protective field height to allow for optimal installation with the application.

Operating status can be seen from a distance. The end cap of the receiver unit is moulded from a semitransparent plastic that is illuminated by LEDs. It shows green for proper operation and red when the protected field has been interrupted or flashing red to indicate fault conditions.

The SLC440COM series features a one-piece extruded, reinforced housing in a compact 28 x 33 mm rectangular profile. This housing profile has proven to be less susceptible to mechanical damage and misalignment from torsion or bending.
