The BNS 33S is a non-contact, electronic safety sensor designed to monitor the closed position of hinged, sliding or removable safety guards with the aid of a coded actuator. This non-contact design limits mechanical wear on the switch and allows for toleration of guard misalignments.
The BNS 33S features a stainless steel housing which is highly resistant to corrosion and chemical agents found in aggressive cleaning agents. The housing is sealed to protection class IP69K standards, allowing it to withstand high temperature and high pressure wash down conditions. Due to these features, the BNS 33S can be used in many applications of the food-processing industry as well as in the chemical and the pharmaceutical industry or anywhere stringent hygienic requirements have to be met.
