Why Choose the Pizzato NXB42AZ1SPK RFID Safety Switch?
The Pizzato NXB42AZ1SPK is an advanced RFID coded safety switch with guard locking designed for reliable machine safety interlocking in industrial automation applications. Part of the innovative Pizzato NX series, this compact safety device combines RFID actuator recognition with a secure locking mechanism to provide dependable protection for safety doors, machine guards and restricted access points.
The NX series is engineered for demanding industrial environments where high safety performance, compact installation and resistance against actuator manipulation are required. The NXB42AZ1SPK uses electronic RFID technology to identify coded actuators without physical contact, helping prevent unauthorised bypassing while maintaining reliable machine protection.
Featuring Mode 1 bistable solenoid operation, the safety outputs are activated when the actuator is inserted and locked. The device provides two safety outputs, a signalling output, dual solenoid activation inputs, programming/reset input and an M12 8-pole connector for stand-alone safety system connections.
