NX B42AZ1SQ0.2 Pizzato NX Series RFID safety switch

Why Choose the Pizzato NX B42AZ1SQ0.2 RFID Safety Switch?

The Pizzato NX B42AZ1SQ0.2 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 on industrial machinery. Its non-contact RFID technology provides coded actuator recognition while the integrated locking mechanism ensures the guard can be retained until the machine safety system permits access.

This configuration uses Mode 1 bistable electromagnetic locking. The OS1 and OS2 safety outputs are activated when the compatible RFID actuator is inserted and locked, providing direct monitoring of the safe guard condition. The actuator recognition system is reprogrammable, allowing the appropriate compatible NX-series actuator to be associated with the switch.

The NX B42AZ1SQ0.2 provides a maximum actuator holding force of 6000 N and incorporates a front hexagonal-key auxiliary release. Electrical integration is provided by an 8-pole M12 connector on a 0.2 m cable, specifically intended for series connection using Y-connectors. The NX platform also provides IP67 / IP69K environmental protection for demanding industrial machine-safety applications.

Reliable RFID Guard Locking for Industrial Machinery

The Pizzato NX Series is designed for machinery where a hazardous condition can remain after a stop command, such as equipment containing rotating components, hot processes or pressurised systems. RFID actuator recognition allows the guard position to be detected without conventional mechanical contact, while the locking mechanism prevents access until the safety-control system determines that opening is permitted.

With Mode 1 operation, the NX B42AZ1SQ0.2 provides safety outputs when the actuator is both inserted and locked. Its 6000 N holding capability, dedicated guard and lock status outputs and series-connection architecture make it particularly suitable for automated machinery containing multiple monitored access points.

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 conditions.
• Machines requiring multiple safety switches connected in series.
