NX B42AZ1SMK Pizzato NX Series IP67 RFID safety switch

Why Choose the NXB42AZ1SMK

The Pizzato Elettrica NXB42AZ1SMK is an advanced NX series RFID safety switch with lock designed for safety interlocking and machine guarding applications in demanding industrial environments. Utilising Mode 1 of bistable solenoid operation, this switch activates its safety outputs (OS1 and OS2) when the actuator is inserted and locked, providing robust access control and tamper resistance in safety circuits.

Equipped with a 12-pole M12 connector for straightforward installation, the device offers multiple safety and signalling I/O channels and carries comprehensive third-party approvals for use in applications up to IP67 and IP69K ratings, according to EN 60529 and ISO 20653.
