Why Choose the Pizzato NG 2D7D412U-F31 Safety Switch?
The Pizzato NG 2D7D412U-F31 is an advanced RFID safety switch with guard locking and integrated control devices, designed for monitoring and securing movable guards on industrial machinery. Part of the Pizzato NG series, this configuration combines electronically coded guard monitoring, high-strength mechanical locking and local operator controls within a robust metal assembly.
The integrated control station incorporates two operator pushbuttons, with a yellow 1NO pushbutton in position 1 and a white 1NO pushbutton in position 2. The switch is supplied complete with the VN NG-F31 high-level coded RFID actuator, providing individual actuator recognition and enhanced protection against manipulation of the machine guarding system.
The NG 2D7D412U-F31 uses the D working principle, keeping the actuator locked while the electromagnet is de-energised. Its locking mechanism provides a maximum actuator holding force of 9750 N, while Mode 1 safety-output operation activates OS1 and OS2 when the actuator is inserted and locked. An orientable head with escape pushbutton provides an internal release function for guarded areas.
Key Advantages
- Combines RFID guard monitoring, high-strength guard locking and integrated operator controls within one device.
- Integrated yellow and white 1NO pushbuttons provide convenient local machine-control functions.
- Supplied with a VN NG-F31 high-level coded RFID actuator for enhanced anti-tampering protection.
- Maximum actuator holding force of 9750 N supports demanding guard-locking applications.
- D working principle keeps the actuator locked while the electromagnet is de-energised.
- Mode 1 safety outputs confirm that the actuator is inserted and the locking mechanism is engaged.
- Dedicated O3 and O4 signalling outputs provide separate actuator-inserted and actuator-locked status information.
- Orientable head with escape pushbutton provides an internal release function for guarded areas.
- Integrated controls can reduce the need for a separate operator-control enclosure at the machine access point.

Integrated Guard Locking and Operator Control
The Pizzato NG 2D7D412U-F31 combines machine-guard interlocking with local operator controls, making it particularly useful where machine functions need to be positioned directly alongside a guarded access point. Its yellow and white 1NO pushbuttons provide two local control inputs, while the RFID safety system electronically monitors the supplied high-level coded actuator and the mechanical locking system retains the guard when access must remain prevented.
With Mode 1 operation, the OS1 and OS2 safety outputs are active when the actuator is inserted and locked, allowing the safety-control system to verify the required guard condition before hazardous machine functions are enabled. Separate O3 and O4 signalling outputs communicate actuator-inserted and actuator-locked status, providing useful diagnostic information for machine controllers and automation systems.
Typical Applications
- Industrial machine guard doors and access gates.
- Robotic cells and automated manufacturing systems.
- Packaging and processing machinery.
- Automated assembly and production lines.
- Conveyor and material-handling systems.
- Machine tools with hazardous or high-inertia movement.
- Guarded access points requiring integrated local operator controls.
- Machinery requiring an internal escape-release function.
- OEM machinery and integrated industrial safety systems.
