Why Choose the Pizzato NSG4AZ1SMK-F40 Safety Interlock Switch?
The Pizzato NSG4AZ1SMK-F40 is a compact and reliable RFID safety interlock switch with solenoid guard locking, designed for industrial machine safety applications where secure door monitoring, actuator detection, and controlled access are required. Manufactured by Pizzato Elettrica, it ensures machinery remains safely locked until all hazardous conditions are eliminated.
This model belongs to the Pizzato NS series of safety locking switches with RFID-coded actuator recognition and integrated solenoid locking. It is widely used in OEM machinery, robotic systems, and automated production environments where consistent safety performance and flexible installation are required.
The NSG4AZ1SMK-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 reliable machine protection during operation. {index=1}

Reliable Guard Locking for Industrial Systems
The Pizzato NSG4AZ1SMK-F40 ensures safe machine operation by keeping protective guards locked until safe conditions are confirmed. The RFID system detects the correct actuator presence, reducing risks of bypass or unintended machine access.
Safety outputs integrate with PLCs or safety controllers, enabling continuous monitoring of guard status, actuator insertion, and lock condition in automated production environments.
Typical Applications
- Industrial automation systems.
- Robotic safety enclosures.
- Packaging and processing machinery.
- Machine tools with safety guarding.
- OEM equipment manufacturing.
- Material handling and conveyor systems.
