Why Choose the Pizzato NXB42CE1SMK RFID Safety Switch?
The Pizzato NXB42CE1SMK is an advanced RFID coded safety switch with guard locking designed for reliable machine safety interlocking in industrial automation environments. Part of the innovative Pizzato NX series, this compact safety device combines RFID actuator recognition with a bistable solenoid locking system to provide secure protection for safety doors, machine guards and restricted access points.
The NX series is engineered for applications requiring high safety performance, tamper-resistant actuator recognition and flexible integration into modern safety circuits. The NXB42CE1SMK uses electronic RFID technology to identify coded actuators without physical contact, helping prevent unauthorised bypassing while maintaining dependable machine protection.
Featuring Mode 1 bistable solenoid operation, the switch activates its safety outputs only when the actuator is correctly inserted and locked. With dual safety inputs, dual safety outputs, diagnostic signalling outputs and an M12 12-pole connector, the NXB42CE1SMK provides a complete safety solution for industrial machinery applications.
