Why Choose the Pizzato NG 2D1D321C-F31 Safety Switch with Guard Locking?
The Pizzato NG 2D1D321C-F31 is an advanced NG series RFID safety switch with guard locking and integrated control devices, designed for monitoring and locking movable guards on industrial machinery. It combines electronically coded actuator detection, electronic safety outputs, solenoid-controlled locking and local operator controls in a robust metal-bodied unit.
This model uses the D working method, meaning the actuator remains locked when the solenoid is de-energised. Its safety outputs operate in activation mode 2, so the OS1 and OS2 outputs become active when the actuator is inserted, while dedicated signalling outputs separately report actuator insertion and lock status.
The NG 2D1D321C-F31 features a rotating head, a metal housing with three M20 × 1.5 threaded conduit entries and an integrated control-device cover. It is supplied complete with the VN NG-F31 high-coding-level actuator, providing a dependable solution for guarded machinery where coded access monitoring, controlled locking and local operator interaction are required.
Key Advantages
- RFID-coded guard monitoring provides dependable actuator recognition.

RFID Guard Monitoring with Integrated Operator Control
The NG 2D1D321C-F31 uses RFID technology to identify the coded actuator and monitor the guard position electronically. Its two safety outputs provide the safety-related switching function, while separate O3 and O4 signalling outputs allow the machine control system to distinguish between the actuator being inserted and the guard being mechanically locked.
With activation mode 2, the safety outputs become active when the actuator is inserted, while the lock status remains independently available through the signalling output. The integrated control-device cover allows operator functions to be positioned directly at the guarded access point, helping reduce the need for separate control stations on suitable machinery.
Typical Applications
- Machine guard doors requiring monitored locking.
- Robotic cells and automated production systems.
- Packaging and processing machinery.
- Machine tools and manufacturing equipment.
- Conveyor and material handling systems.
- Guarded access points requiring local operator controls.
- Industrial machinery requiring RFID-coded guard monitoring.
