Why Choose the Pizzato NX B52AZ1SMK RFID Safety Switch?
The Pizzato NX B52AZ1SMK is a compact RFID safety switch with guard locking from the Pizzato NX Series, designed for monitoring movable guards and controlling access to hazardous areas of industrial machinery. It combines non-contact RFID actuator recognition with high-force bistable electromagnetic locking and electronic safety monitoring.
This configuration operates in Mode 1, with safety outputs OS1 and OS2 active when the actuator is inserted and locked. The switch also incorporates an EDM feedback input I5 for external device monitoring, alongside dedicated outputs for actuator-inserted and actuator-locked status.
The NX B52AZ1SMK is supplied without an actuator and provides reprogrammable actuator recognition, allowing a compatible NX-series RFID actuator to be associated with the switch. It delivers a maximum holding force of 6000 N, features a front hexagonal-key auxiliary release, a 12-pole M12 connector, RGB LED status indication and IP67 / IP69K environmental protection.
Key Advantages
- Combines RFID guard monitoring and bistable electromagnetic guard locking in one compact device.

Reliable RFID Guard Locking with EDM Monitoring
The Pizzato NX B52AZ1SMK is designed for machinery where the safety system must monitor both guard position and the locked condition before permitting hazardous machine operation. Mode 1 provides a locking safety function in which OS1 and OS2 are active with the actuator inserted and locked, with a safety capability up to PL e / SIL 3 when correctly integrated into the specified safety architecture.
The additional EDM feedback input I5 distinguishes this configuration from corresponding NX variants without EDM monitoring. Together with its 6000 N holding force, dedicated O3 and O4 status outputs, front auxiliary release, M12 connection and RGB LED indication, the NX B52AZ1SMK provides a comprehensive solution for modern guarded machinery.
Typical Applications
- Machine safety doors and movable guards.
- Robotic cells and guarded automation systems.
- Automated manufacturing and assembly machinery.
- Packaging and processing equipment.
- Conveyor and material handling systems.
- Machinery with hazardous run-down or residual movement.
- Safety systems requiring external device monitoring via EDM feedback.
