Euchner Safety switch w/o door monitoring contact Part number 091746

This Euchner STP1 safety switch operates on the closed-circuit current principle, with guard locking maintained by spring force and released by applying voltage to the guard locking solenoid. It provides slow-action switching with 2 NC and 2 NO contacts, plus guard lock monitoring via positively driven and NO contacts, giving reliable status feedback for the interlocking circuit. The switch features a reinforced thermoplastic housing with silver alloy, gold-flashed contacts, an IP67 degree of protection and an ambient temperature range of -20 to 55°C, suiting it to demanding industrial guarding applications where any mounting orientation is required.
