Schmersal 101157379 AZ 16 ZVRK-M20 – Safety Door Switch with Separate Actuator and Latching
The Schmersal 101157379 (AZ 16 ZVRK-M20) is an electromechanical safety switch from the Schmersal AZ 16 series, used with a separate actuator. It monitors the position of hinged, sliding and removable safety guards: when the guard is opened and the actuator is withdrawn, the positive-break NC contact opens.
This version has:
- Increased latching force of 30 N, which holds the guard closed against vibration or light rebound.
- Three M20 × 1.5 cable entries.
- High contact reliability at low voltages and currents.
- Compact housing: 52 × 90 × 30 mm, double-insulated thermoplastic, IP67.
