Why Choose the Pizzato NXB42AZ1SB2-F61 RFID Safety Switch with Lock?
The Pizzato NXB42AZ1SB2-F61 is a high-performance RFID safety switch with guard locking from the Pizzato Elettrica NX series, designed to provide secure access control and reliable safety monitoring for industrial machinery and automation systems. Combining advanced RFID-coded actuator technology with a bistable solenoid locking mechanism, this safety switch delivers dependable protection for machines where hazardous movement must be controlled before access is permitted.
The NX series is developed for modern industrial safety applications requiring high coding levels, tamper resistance and simple integration with safety controllers. The NXB42AZ1SB2-F61 provides electronic safety outputs, diagnostic signalling and robust construction, making it suitable for machine guards, robotic cells, production lines and automated equipment.
Featuring Mode 1 bistable solenoid operation, the device activates the safety outputs only when the RFID actuator is correctly inserted and locked. Its compact design, RGB LED status indication and IP67/IP69K protection allow reliable operation in demanding industrial environments.

Reliable RFID Guard Locking for Industrial Safety
The Pizzato NX series uses RFID technology to provide secure actuator identification and prevent unauthorised bypassing of machine safety systems. Each actuator provides high coding security, allowing reliable monitoring of safety guards and access points in automated machinery.
The bistable locking mechanism improves system efficiency by maintaining the locked or unlocked condition without continuous solenoid power consumption. This reduces heat generation and supports reliable operation in modern industrial automation environments.
Typical Applications
Machine guard locking and safety interlocking systems.
Robotic cells and automated production lines.
Packaging and processing machinery.
Industrial conveyors and material handling equipment.
CNC machines and manufacturing systems.
Machines with hazardous residual movement after shutdown.
