Why Choose the Pizzato NG 2D1D411F-F31 Safety Switch with Lock and Integrated Control Devices?
The Pizzato NG 2D1D411F-F31 is an advanced NG series safety switch with solenoid guard locking, integrated control devices and 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 housing.
The NG 2D1D411F-F31 uses the D working method, meaning the actuator remains locked when the solenoid 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 green 1NO+1NC pushbutton and one red 1NO+1NC pushbutton, and is supplied complete with the VN NG-F31 high-level coded actuator. The switch features a rotating head, three M20 × 1.5 threaded conduit entries and a maximum actuator holding force of 9750 N, with IP65 protection for industrial installations.
Key Advantages
- Combines safety monitoring, guard locking and local operator controls in one device.
- Integrated green and red pushbuttons reduce the need for separate operator-control components.
- Each integrated pushbutton provides 1NO+1NC contacts.
- Power-to-unlock operation keeps the actuator locked when the solenoid is de-energised.
- Maximum actuator holding force of 9750 N provides strong mechanical guard retention.
- Supplied complete with 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.

High-Level Coded Guard Locking with Integrated Operator Controls
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 2D1D411F-F31 combines electronic actuator monitoring with mechanical guard locking, allowing the machine safety system to verify that the actuator is correctly inserted and securely locked before the safety outputs become active.
The integrated green and red 1NO+1NC pushbuttons provide two local operator-control functions directly at the guarded access point. Combined with the VN NG-F31 high-level coded actuator, this configuration provides guard locking, enhanced actuator coding and operator controls in one assembly, while dedicated O3 and O4 outputs provide clear actuator insertion and locking status.
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 local green and red operator pushbuttons.
- Industrial machinery requiring high-level coded guard locking.
