Schmersal ZS 236-11Z-M20 is a safety position switch with a roller plunger actuator and a single changeover contact (1 NO / 1 NC), designed for guarding and door-interlock applications in safety circuits. It features a thermoplastic enclosure reinforced with glass fiber, a cable entry sized M20, and snap-action contacts rated up to 4 A at 230 VAC. The roller plunger detects guard position and interfaces with safety relays to help ensure immediate machine shutdown when a guard is opened. This model is well-suited for compact, robust installations in machine guarding where reliable monitoring of door or gate positions is required.
