Schmersal N-Series hygienic IP69K operator devices

Schmersal’s N-Series IP69K range of signalling devices has been designed and tested specifically for hygiene-sensitive environments. The range consists of command and signalling devices including emergency stop mushroom buttons, push-buttons, illuminated push-buttons and pilot lights, selector switches and main switches.

Constructed using the ‘hygienic design’ principle, there are no corners or edges, which prevents contamination and allows the device to be cleaned and maintained easily.

The series is UV and ozone resistant, and is also resistant to cleaning agents typically used in the food processing industry. Special seals prevent the penetration of product residue in the gaps between the fixed and moving parts, effectively preventing the formation of bacteria that are hard to reach for cleaning.

Blue sealing bellows have also been added to the push-button range for detection by optical sensors. Since the colour blue is not a natural food colour, it is the most effective colour to contrast against food products when detecting foreign objects.
