Schmersal BNS 36-02Z-ST-R is a magnetic safety interlock switch from the BNS 36 family, designed to monitor guarded openings on industrial equipment. It features two normally closed contacts (2 NC), a fiberglass-reinforced thermoplastic housing with screw mounting, and an IP67 enclosure rated for harsh environments. The unit operates on a nominal 75 V DC supply and withstands temperatures from -25 to 70 °C, making it suitable for demanding factory floors. Used as part of a guarding circuit, it interfaces with safety relays or controllers to ensure the machine stops when a guard is opened.
