Pizzato NX series RFID safety switch

Click2Contact

The NX series safety switch from Pizzato is based on RFID technology, bistable operation and three actuator entries. The safety switch also features a robust metal head to reach the PL e and SIL 3 safety levels.

With compact dimensions of 30x30x94.5 mm, the safety switch is suitable for applications in confined spaces. The switch is also equipped with an illuminated RGB-LED cover that enables immediate diagnosis of the function states of the inputs and outputs. As a result, this display can easily be read from a distance and from all viewing angles.

The safety switches of the NX series are designed as bistable switches. The internal solenoid (with which the device is locked or unlocked) operates in the bistable mode, ie, the solenoid is activated by short electrical impulses that move it to the locked or unlocked position.

The housing is made of two materials: the metal head provides resistance to impacts from the actuator and resistance to pulling when the door is locked, while the technopolymer body provides flexibility in the design.

The safety switch is always mounted using the two front M5 screws with a hole spacing of 20 mm, whereby it does not matter whether the doors open to the right or left or if they are sliding or hinged doors. The switch is equipped with an auxiliary release that can be actuated with an allen key.
