Schmersal AZ16-12VRK-M20 is a keyed safety interlock switch from the AZ16 family, designed to secure access doors on industrial machinery and ensure the safety circuit is interrupted when a guard is opened. It features a fiberglass-reinforced thermoplastic housing and a NO/2NC contact arrangement for the safety circuit, with three M20 cable-entry points for wiring and compatibility with Schmersal AZ16 actuators and mating hardware. The AZ16-12VRK-M20 designation identifies the specific variant of the AZ16 series (12 variant with a keyed actuator) and its M20 wiring configuration.
