Schmersal SLC/SLG440 IP69K safety light curtains and grids

Schmersal has released the SLC/SLG440 IP69K range of IP69K safety light curtains and light grids. Suitable for use in hygiene-sensitive sectors including food, pharmaceuticals, meat and milk processing, the range is resistant to all daily cleaning processes prevalent in such industries.

Its design protects against ingress of water during close-range high-pressure and high-temperature spray. Based on strict requirements, the seals of the SLC/SLG440 series can withstand frequent cleaning with water, alkali solutions, foam, hot steam or high-pressure jets.

The SLC/SLG 440 IP69K locking caps are manufactured in stainless steel (V4A) as are the cable inlet and the fastening parts. Transparent protective tubes are made of polycarbonate, offer high resistance to cleaning agents and can withstand strong mechanical loads. If spray lances should accidentally strike the SLC/SLG 440 IP69K’s enclosure during pressure washing in food production or there is impact with the enclosure, the safety and protection function will continue to work due to the robust protective tubes.

The SLC440 IP69K range is available in lengths from 170 to 1920 mm and two resolutions of 14 and 30 mm, and as 2, 3 and 4 light beam grids. They are suitable for use in safety circuits up to PLe (EN 13849) or SIL3 (IEC 61508).
