Why Choose the Pizzato NSD4AZ1SM3 Safety Locking Switch?
The Pizzato NSD4AZ1SM3 is an industrial RFID safety interlock switch with guard locking designed to monitor and secure movable machine guards, doors and access points. Part of the Pizzato NS safety locking switch series, it combines contactless RFID actuator detection with electromagnetic guard locking and electronic safety monitoring for integration into modern machinery safety systems.
The NS series is intended for applications where a guard must remain secured until hazardous machine conditions have ceased. Its electronic architecture monitors guard and locking conditions through safety outputs, while RFID technology provides reliable non-contact detection of a compatible coded actuator without conventional mechanical safety contacts.
The NSD4AZ1SM3 uses a robust technopolymer construction and the NS series locking mechanism provides a maximum actuator holding force of 2,100 N. This SM3 configuration provides a 3 m connection cable, making it suitable for fixed wiring into machine control and safety systems where a factory-fitted cable is preferred.

Reliable Guard Locking for Industrial Machinery
Safety interlock switches with guard locking are used where opening a movable guard before hazardous machine movement has stopped could expose personnel to risk. The Pizzato NSD4AZ1SM3 combines RFID actuator detection with monitored locking so that a machine safety system can supervise the condition of the guard before allowing hazardous functions or controlled access.
The NS series is particularly suited to automated machinery requiring dependable electronic safety monitoring and robust guard retention. Its RFID technology, high holding force and integrated diagnostic indication help machine builders create practical safety solutions for production equipment, robotic cells and other guarded machinery.
Typical Applications
- Industrial machine guard doors and access panels.
- Robotic cells and automated manufacturing equipment.
- Packaging and processing machinery.
- Machines with hazardous residual or run-down movement.
- Automated assembly and production lines.
- Conveyor and material handling systems.
- OEM machinery and integrated machine safety systems.
