Why Choose the Pizzato NSG3AZ1SQK-F40 Safety Interlock Switch?
The Pizzato NSG3AZ1SQK-F40 is a robust RFID safety interlock switch with solenoid guard locking, designed for industrial machine safety applications where reliable door monitoring, actuator detection, and controlled access are required. Manufactured by Pizzato Elettrica, it ensures machinery remains safely secured until all hazardous conditions have been eliminated.
This model belongs to the Pizzato NS series of safety locking switches featuring RFID-coded actuator recognition and integrated solenoid locking. It is widely used in OEM machinery, robotic cells, and automated production systems where dependable guard safety and flexible installation are essential.
The NSG3AZ1SQK-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 properly closed and the actuator is correctly detected. The F40 actuator provides a low-coded universal solution suitable for standard industrial applications. {index=1}
