Why Choose the Pizzato NG 2D1D311H-F31 Safety Switch with Guard Locking?
The Pizzato NG 2D1D311H-F31 is an advanced NG series RFID safety switch with guard locking and integrated control device, designed for monitoring and locking movable guards on industrial machinery. It combines electronically coded actuator detection, safety outputs, solenoid-controlled locking and an integrated pushbutton within a robust metal-bodied safety device.
This configuration uses the D working principle, meaning the actuator remains locked when the solenoid is de-energised. The safety outputs are activated only when the actuator is both inserted and locked, providing guard-position and lock-state supervision for machinery where access must remain prevented until hazardous movement or processes have stopped.
The NG 2D1D311H-F31 features a rotating head, metal housing with three M20 × 1.5 threaded cable entries and an integrated white 1NO + 1NC pushbutton. It is supplied complete with the VN NG-F31 high-coding-level actuator and provides IP65 protection according to EN 60529 for dependable installation on industrial machine guards and access doors.

RFID Guard Monitoring with Solenoid-Controlled Locking
The NG 2D1D311H-F31 combines RFID actuator recognition with electronically monitored guard locking. When the high-coding-level VN NG-F31 actuator enters the switch head, the device can identify its presence and monitor the locking condition independently. In activation mode 1, the OS1 and OS2 safety outputs become active only when the actuator has been correctly inserted and locked.
The D working principle provides locking with the solenoid de-energised, making the switch suitable for machinery where the guard must remain locked until a controlled release is permitted. Dedicated signalling outputs provide actuator-inserted and actuator-locked status information, while the integrated white 1NO + 1NC pushbutton allows an additional machine-control function to be incorporated directly at the guard access point.
Typical Applications
- Machine guard doors requiring monitored locking.
- Automated production and assembly machinery.
- Robotic cells and guarded automation systems.
- Packaging and processing machinery.
- Machine tools and manufacturing equipment.
- Conveyor and material handling systems with guarded access points.
- Industrial machinery requiring RFID-coded guard monitoring and operator controls.
