Why Choose the Pizzato NX B42AZ1SPK RFID Safety Switch?
The Pizzato NX B42AZ1SPK is a compact RFID safety switch with guard locking designed for monitoring and controlling access through movable guards, safety doors and protected areas on industrial machinery. Part of the Pizzato NX Series, it combines non-contact RFID actuator recognition, bistable electromagnetic locking and electronic safety outputs in a compact machine-safety device.
This base configuration is supplied without an actuator and uses reprogrammable RFID actuator recognition, allowing a compatible NX-series actuator to be selected separately. Mode 1 operation activates both OS1 and OS2 safety outputs when the actuator is inserted and securely locked, making the switch suitable for applications where the safety function depends on both guard position and lock status.
The NX B42AZ1SPK provides a maximum guard-locking force of 6000 N and features a front hexagonal-key auxiliary release. An 8-pole M12 connector supports stand-alone electrical connection, while the illuminated multicolour RGB LED cover provides clear visual status indication. Environmental protection is rated IP67 according to EN 60529 and IP69K according to ISO 20653.

Reliable RFID Guard Locking for Industrial Machinery
The Pizzato NX Series provides non-contact RFID guard detection together with electromagnetic locking for machinery where access must remain restricted until safe conditions have been established. The NX B42AZ1SPK uses Mode 1 operation so that its two safety outputs are activated when the RFID actuator is correctly inserted and the guard is locked.
With a maximum locking force of 6000 N, compact construction and a dedicated O3 actuator-status output, the NX B42AZ1SPK provides a robust solution for modern machine guarding. Its front auxiliary release supports authorised intervention, while the 8-pole M12 connection and RGB status indication simplify installation, commissioning and diagnostics.
