Why Choose the Pizzato NSG4AZ1SPK-F40 Safety Interlock Switch?
The Pizzato NSG4AZ1SPK-F40 is a reliable RFID safety interlock switch with solenoid guard locking, designed for industrial machine safety applications where controlled access, actuator detection, and dependable locking performance are essential. Manufactured by Pizzato Elettrica, it ensures machinery remains safely secured until hazardous conditions have been fully eliminated.
This model belongs to the Pizzato NS series safety interlock switches featuring RFID-coded actuator recognition and integrated solenoid locking technology. It is widely used in OEM machinery, robotic safety cells, and automated production systems where consistent guarding protection and flexible installation are required.
The NSG4AZ1SPK-F40 operates in a G working method configuration, meaning the actuator is locked using a de-energised 24 Vdc solenoid. Safety outputs are enabled only when the guard is closed and the actuator is correctly detected, ensuring safe and controlled machine operation. {index=1}
