Why Choose the Pizzato NG 2D1D412P-F31 Safety Switch with Lock and Integrated Control Devices?
The Pizzato NG 2D1D412P-F31 is an advanced NG series safety switch with solenoid guard locking, integrated control devices and a high-level coded actuator designed for monitoring and controlling access to hazardous areas of industrial machinery. It combines electronic safety monitoring, high-strength mechanical guard locking and local operator controls within a robust metal-bodied safety device.
The NG 2D1D412P-F31 uses the D working principle, meaning the actuator remains locked when the electromagnet is de-energised. Its Mode 1 safety configuration activates the OS1 and OS2 safety outputs when the actuator is correctly inserted and locked, while dedicated O3 and O4 signalling outputs provide separate actuator-inserted and actuator-locked status information to the machine control system.
This configuration incorporates two integrated pushbuttons, comprising one white 1NO pushbutton in position 1 and one blue 1NO pushbutton in position 2. It is supplied complete with the VN NG-F31 high-level coded actuator and features a rotating head, metal housing, three M20 × 1.5 threaded conduit entries, auxiliary release and a locking force of 9750 N.
Key Advantages
- Combines safety monitoring, guard locking and local operator controls in one device.
- Integrated white and blue pushbuttons provide two convenient local machine-control functions.
- Each integrated pushbutton provides a 1NO contact.
- Power-to-unlock operation keeps the actuator locked when the electromagnet is de-energised.
- High locking force of 9750 N provides strong mechanical guard retention.
- Supplied complete with the VN NG-F31 high-level coded actuator.
- High-level actuator coding provides enhanced protection against foreseeable manipulation.
- Separate signalling outputs indicate actuator inserted and actuator locked conditions.
- Auxiliary release provides an additional means of mechanically releasing the guard lock when required.

Integrated Guard Locking and Local Operator Control
Guard-locking safety switches are used where opening a machine guard before hazardous movement or processes have stopped could expose personnel to risk. The Pizzato NG 2D1D412P-F31 combines electronic actuator monitoring with mechanical guard locking, allowing the safety control system to verify that the actuator is correctly inserted and securely locked before the safety outputs become active.
The integrated white and blue 1NO pushbuttons provide two local operator-control functions directly at the guarded access point, helping reduce the need for separate control stations. Combined with the VN NG-F31 high-level coded actuator, 9750 N locking force, auxiliary release and separate O3 and O4 status outputs, this configuration provides a comprehensive guard-locking and local-control solution for industrial machinery.
Typical Applications
- Machine guard doors and access panels.
- Robotic cells and automated manufacturing systems.
- Packaging and processing machinery.
- Automated production and assembly lines.
- Machining centres and industrial machine tools.
- Conveyor and material handling equipment.
- Guarded access points requiring two local operator pushbuttons.
- Industrial machinery requiring high-level coded guard locking.
