Why Choose the Pizzato NX B42AZ1SE2 RFID Safety Switch?
The Pizzato NX B42AZ1SE2 is a compact RFID safety switch with guard locking designed for reliable monitoring and controlled locking of movable guards on industrial machinery. As part of the advanced Pizzato NX series, it combines non-contact RFID actuator recognition, bistable guard locking and redundant electronic safety outputs in a compact format suited to machine-building and automation applications.
This configuration operates in Mode 1 with a bistable solenoid, with safety outputs OS1 and OS2 activated when the actuator is inserted and locked. It provides two safety outputs, an actuator-inserted signalling output, two solenoid activation inputs and a programming/reset input, giving machine designers a comprehensive interface for guard monitoring and safety control.
The NX B42AZ1SE2 features a 2 m halogen-free PUR integrated cable, a front auxiliary release operated with a hexagonal key and an illuminated RGB LED cover for multicolour status signalling. It provides IP67 and IP69K protection and a maximum locked-actuator holding force of 6000 N, while this particular model is supplied without an actuator.

Reliable RFID Guard Locking for Industrial Machinery
RFID safety switches such as the Pizzato NX series combine coded non-contact guard detection with mechanical guard locking. This makes them particularly suitable for machines where a hazardous condition can remain after a stop command, such as equipment containing rotating components, high-temperature parts or pressurised processes.
The NX B42AZ1SE2 uses a bistable operating principle and provides dedicated safety, signalling and solenoid-control connections for integration into machine safety systems. Its high holding force, compact construction, robust environmental protection and visual status signalling make it well suited to modern automated equipment where reliable access control and straightforward diagnostics are required.
Typical Applications
- Machine guard doors and protective access panels.
- Industrial automation and robotic cells.
- Packaging and processing machinery.
- Production and assembly equipment.
- Machinery with hazardous residual movement after shutdown.
- Equipment containing hot or pressurised process areas.
- Guarded machinery requiring controlled operator access.
- Industrial safety systems requiring RFID guard monitoring and locking.
