Schmersal AZ16-ZVK-M20 Industrial Safety Switch

The Schmersal AZ 16 ZVK-M20 is a safety switch with a separate actuator designed to safeguard machine guarding—such as sliding, hinged, or removable guards—so that the guarding must be closed to energize the safety circuit. It uses a thermoplastic, double‑insulated enclosure in the AZ 16 family, performing with compact dimensions around 52 x 90 x 30 mm and M20 cable entry for straightforward wiring. The device is built for EN ISO 14119 type 2 interlocking devices, delivering reliable interlock performance in industrial environments. This model ships with a separate actuator and the AZ 15 16‑B1‑2053 key, enabling keyed operation and secure manual reset when safety conditions permit. In line with the AZ 16 family, it offers universal coding, long service life, and high reliability at low voltages and currents, and it is designed to be resistant to soiling in demanding workplaces. Common applications include safeguarding access points on presses, conveyors, and packaging machines, where the guard must be closed to allow operation. Whether used as a standalone interlock or integrated into a broader safety system, AZ 16 ZVK-M20 combines straightforward installation with certified safety performance and compatibility within Schmersal’s safety portfolio.
