Schmersal 101143124 AZ 16 ZVRK-ST – Safety Door Switch with M12 Connector and Latching
The Schmersal 101143124 (AZ 16 ZVRK-ST) 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 When the guard is opened and the actuator is withdrawn, the positive-break NC contact opens.
What this version adds:
- M12 connector: 4-pole plug at the bottom, for quick plug-in wiring.
- Increased latching force: 30 N, which holds the guard closed against vibration or light rebound.
The housing is compact (52 × 90 × 30 mm), made of double-insulated thermoplastic and rated IP67.
