Hygienic and extremely robust
Schmersal has developed a new enclosure for our safety light curtains and grids which withstands daily cleaning processes prevalent in hygiene-sensitive applications of the food industry, pharmaceuticals, and meat and milk processing.
Thanks to a sophisticated, detailed design, this enclosure achieves an ingress protection rating of IP69 (to IEC 60529), preventing water damage during close-range high-pressure and high-temperature spray downs. The independent testing laboratory Ecolab has also verified the high resistance to common cleaning agents. This means that the seals on the safety light curtain housing meets very strict requirements and are able to withstand frequent cleaning with water, alkali solutions, foam, hot steam, or high-pressure jets.
Made of polycarbonate (PC), the transparent protective tubes not only offer high resistance to cleaning agents, but also tolerates strong mechanical loads. If spray lances should accidentally strike the enclosure during pressure washing in food production or a transport should collide with the enclosure, the safety and protection function will continue to work thanks to the robust protective tubes.
The endcaps can be ordered in stainless steel (SH) or polyamide (PH).
The enclosure offers a greater availability and a long service life for safety light curtains and grids, all in a compact 50 mm diameter design. This hygienic and robust enclosure is available for SLC440COM and SLC440 safety light curtains and grids, in protection heights up to 1770 mm.
