Schmersal AZ 15 ZVRK-M20 Safety Switch

Schmersal AZ 15 ZVRK-M20 is a safety switch with a separate actuator for machine guarding, featuring a normally closed SPST-NC contact rated up to 4 A and compatible with 230 VAC or 24 VDC control circuits. Encased in a thermoplastic housing measuring 52 x 75 x 30 mm, it is double insulated and IP67-rated for dust and water protection, with three M20 x 1.5 cable entries to accommodate wiring flexibility. As part of the AZ 15 family, it offers universal coding, a large wiring compartment, and mounting versatility with both slotted holes for adjustment and circular holes for location, while its design is described as insensitive to soiling. Typical applications include guarding access doors on presses, conveyors, and other automated machinery, where a robust, codable interlock is required to meet safety standards and integrate with Schmersal actuators and safety relays.
