Safety light curtains are a non-separating guard used for the protection of hazardous areas. They detect the passage of objects and direct the machine to stop the hazard. Because they do not provide a physical barrier, consideration must be made to place them a suitable distance from the hazard point to ensure the hazard is stopped in time.

Schmersal’s safety light curtains feature a one-piece extruded reinforced housing. This housing profile has proven to be less susceptible to mechanical damage and misalignment from torsion or bending because it does not rely on the lens for structural integrity. They are suitable for use in safety circuits up to PLe (EN 13849) or SIL3 (IEC 61508).

They are also available as safety light grids (SLG) with 2, 3, or 4 beams, for perimeter guarding.
