Why Choose the Pizzato NSD4AZ1SMK-F40 Safety Interlock Switch?
The Pizzato NSD4AZ1SMK-F40 is a reliable RFID safety interlock switch with solenoid guard locking, designed for industrial machine safety applications where dependable access control and actuator monitoring are required. Manufactured by Pizzato Elettrica, it ensures that hazardous machinery remains securely locked until all safety conditions are satisfied.
This model belongs to the Pizzato NS series of safety locking switches with integrated RFID actuator detection and de-energised solenoid locking. It is widely used in OEM machinery, robotics, and automation systems where safe guarding and simplified wiring architecture are essential.
The NSD4AZ1SMK-F40 operates in a D working method configuration, meaning the actuator is locked with a de-energised solenoid and safety outputs are enabled only when the guard is correctly closed and secured. The F40 actuator version uses a low-coded universal actuator, making it suitable for standard industrial applications where flexibility is required. {index=1}

Reliable Guard Locking for Industrial Safety Systems
The Pizzato NSD4AZ1SMK-F40 is designed to prevent access to hazardous machinery until safe conditions are met. Its RFID-based system detects actuator presence and position, while the solenoid locking mechanism ensures the guard remains closed during unsafe machine states.
The integrated safety outputs allow connection to safety controllers or PLC systems, enabling continuous monitoring of guard status, actuator insertion, and lock condition in real time.
Typical Applications
- Industrial robotic safety enclosures.
- Automated production machinery.
- Packaging and processing systems.
- Machine tools with safety guarding.
- OEM industrial automation systems.
- Material handling and conveyor safety systems.
