Schmersal AZ152VRK-M16 Safety Interlock Switch

Schmersal AZ16 ZVRK-M16 safety interlock switch is a key‑operated guard interlock with a separate actuator, designed to secure access doors on automated machinery. It provides two safety contacts (NC + NO) for monitored safety circuits, housed in a fibreglass‑reinforced thermoplastic enclosure with IP67 protection and three cable entries for flexible installation. The device uses a 16 mm actuator interface (M16) and employs a positive‑break mechanism to ensure the safety function interrupts the circuit when the guard is opened or closed. Typical applications include guarding access to presses, conveyors, and robot work cells where a robust interlock is required for fail‑safe door control.
