The mounting plates of the BRÜHL-SN-S trip cam system are rounded laser edge parts made of robust, galvanized steel. The trip cam profile has a powder-coated surface in door color. Two roller lever switches (design 1) for safe two-signal interrogation can be mounted on the trip cam system in a manufacturer-independent and precisely fitting manner, which can have a positive effect on the performance level or on the safety category as part of the risk assessment. Suppliers of suitable safety switches include the companies Bernstein, Euchner, Rockwell Automation, Schmersal, Sick and Siemens.
