Why Choose the Pizzato NG 2D7D411A-F31 Safety Switch with Lock?
The Pizzato NG 2D7D411A-F31 is a robust NG series RFID safety switch with guard locking, designed to monitor movable machine guards while preventing access to hazardous areas until safe conditions are established. It combines non-contact coded actuator detection, electronically monitored locking and safety outputs in a heavy-duty metal housing for industrial machinery and automation systems.
This model uses the Pizzato D working method, meaning the actuator remains locked when the solenoid is de-energised. Its rotating head incorporates an escape pushbutton, while two safety inputs, two safety outputs and dedicated actuator and lock-status signalling outputs support integration with modern machine safety controllers.
The NG 2D7D411A-F31 operates in Mode 1, with the OS1 and OS2 safety outputs active only when the actuator is inserted and locked. It is supplied complete with the VN NG-F31 high-coding-level actuator, provides a maximum holding force of 9750 N, and offers IP67 and IP69K protection for demanding industrial environments.
Key Advantages
- Combines RFID guard monitoring and monitored guard locking in one industrial safety device.
- 9750 N maximum holding force provides secure retention of guarded machine access points.
- VN NG-F31 high-coding-level actuator supports enhanced protection against actuator substitution.
- D working method keeps the actuator locked when the solenoid is de-energised.
- Two safety inputs and two electronic safety outputs simplify safety-system integration.
- Separate signalling outputs provide actuator-inserted and actuator-locked status information.
- IP67 and IP69K protection supports use in demanding industrial environments.
- Rotating head with escape pushbutton provides an emergency egress function from inside a guarded area.

Reliable RFID Guard Locking for Industrial Machinery
Guard-locking safety switches are used where personnel must be prevented from entering a hazardous machine area until dangerous movement or another residual hazard has ceased. The Pizzato NG series combines RFID-based actuator detection with electronically monitored guard locking, allowing the guard condition to be incorporated into the machine's safety-related control architecture.
For the NG 2D7D411A-F31, Mode 1 operation requires the actuator to be both inserted and locked before the OS1 and OS2 safety outputs become active. The high-coding-level F31 actuator provides individual coding, while separate O3 and O4 signalling outputs provide useful guard and lock-status information for machine diagnostics and control.
Typical Applications
- Industrial machine safety doors and movable guards.
- Robotic cells and automated production areas.
- Packaging and processing machinery.
- Machine tools with residual hazardous movement.
- Automated assembly and manufacturing equipment.
- Conveyor and material handling systems.
- Guarded areas requiring an internal escape release function.
- OEM machinery and industrial automation systems.
