Why Choose the Pizzato NG 2D1D511A-F31 Safety Switch?
The Pizzato NG 2D1D511A-F31 is a robust NG series RFID safety switch with guard locking, designed for reliable monitoring and controlled access through movable guards and protective doors on industrial machinery. It combines electronically coded actuator detection, monitored guard locking and safety-related electronic outputs in a heavy-duty metal device for modern machine safety systems.
This configuration uses the D operating principle, meaning the actuator is locked while the solenoid is de-energised, and includes a sealable auxiliary release device. The NG 2D1D511A-F31 provides two IS1–IS2 safety inputs, two OS1–OS2 safety outputs, separate O3 and O4 signalling outputs and an I5 EDM feedback input for external device monitoring.
The switch operates in Mode 1, with safety outputs OS1 and OS2 active when the actuator is inserted and locked. It is supplied with the VN NG-F31 high-level coded RFID actuator, which is uniquely coded and associated with the switch, helping provide a high level of protection against actuator substitution in accordance with EN ISO 14119.

Reliable RFID Guard Locking with EDM Monitoring
Guard-locking safety switches are used where a movable protective guard must remain secured until hazardous machine conditions have ended. The Pizzato NG 2D1D511A-F31 monitors actuator insertion and locking status and provides safety outputs that become active only when the actuator is inserted and locked, making it suitable for machines with hazardous elements that may have residual movement or inertia.
The additional EDM input distinguishes this configuration from the corresponding standard NG 2D1D411A version by allowing feedback from external switching devices to be monitored. Combined with the uniquely coded F31 RFID actuator, high locking force and robust metal construction, the NG 2D1D511A-F31 provides a sophisticated safety solution for demanding automated machinery.
Typical Applications
- Machine guard doors and movable protective guards.
- Robotic cells and automated manufacturing systems.
- Packaging and processing machinery.
- Automated production and assembly equipment.
- Conveyor and material handling systems.
- Machinery requiring external device monitoring through EDM feedback.
- OEM machinery and factory automation installations.
