Thus, systems that comply with IEC 61496 Safety Category 2, can be used wherever processes involve major temperature fluctuations, and cleaning with steam or aggressive detergents, e.g. in the food industry.
This protected safety technology has already been implemented successfully on cheese and meat processing machines.
The C 2000 and M 2000 series of safety light curtains are employed for safeguarding hazardous areas. A newly developed protective housing, a PMMA acrylic pipe with V4A stainless steel end-caps, now also allows them to be used under extreme environmental conditions.
The housing is compactly built so that no inaccessible recesses are formed. The housing materials are resistant to all common standard cleaning processes and detergents.
A Goretex PreVent membrane is integrated in the end-caps to ensure that the devices do not "fog up". This prevents temperature fluctuations and the ingress of dampness.
The cable inlet is achieved using industrially tried-and-tested PG screw fittings.
