New NX series RFID safety switch with lock


Maximum technology in the minimum volume:
The smallest RFID safety switch with lock in the world

The new NX series RFID safety switch with lock marks a significant breakthrough in industrial safety.
Due to its small size, it distinguishes itself as the world's smallest safety switch with lock and RFID technology. 


Maximum technology
in the minimum volume

The company's many years of experience in the field of safety switches coupled with the new design approach has resulted in a device with dimensions of just 30x30x94.5 mm.  

This makes it the smallest switch in the world with a volume of only 85 cm3, thus providing the ideal solution for installations in very confined spaces. 

High safety standards guaranteed 

This switch offers all the well-established features of the Pizzato brand, such as the RFID technology installed in the actuator and the highest guaranteed safety levels PL e and SIL 3, thereby providing a high degree of safety. 


Metal head and
technopolymer body

The housing of the NX series switch is made of two different materials: the metal head ensures maximum impact and tensile strength when the door is locked, and the technopolymer body ensures the lightweight and flexible construction of the device. 


Fast diagnosis of
operational state

A distinctive feature of the NX switch is the illuminated cap positioned on the head of the device, allowing the operator to quickly and immediately diagnose the functional states of inputs and outputs with the help of the incorporated RGB LEDs.

Bistable operating principle 

This new operating method activates the internal solenoid by means of short electrical impulses that stabilise its position in either the unlocked or locked state. The most significant advantage resulting from this is the considerable reduction in energy consumption and warming up of the switch. 

Straightforward mounting 

Mounting the NX switch on a guard is carried out using just two M5 screws on the front with a hole spacing of 20 mm, whereby it plays no role whether the doors open to the right or left or if they are sliding or hinged doors.

This is achieved by the presence of three entry openings for the actuator, which eliminate the need to rotate the head or the switch. 


Technical features and other advantages 

Further aspects of the device are: 

  • Auxiliary release via hexagonal key 
  • Actuator can be rotated 90° 
  • Jointed actuator for inaccurately closing guards
