Why Choose the Pizzato NG 2D1D411E-F31 Safety Switch with Lock?
The Pizzato NG 2D1D411E-F31 is an advanced NG series safety switch with guard locking and integrated control devices, designed for monitoring and locking movable guards, doors and access points on industrial machinery. It combines electronic safety monitoring, a robust metal housing, integrated operator controls and a high-coding-level actuator in a single machine-safety device.
The switch uses the D working method, in which the actuator is locked when the solenoid is de-energised. Its safety outputs are activated when the actuator is both inserted and locked, supporting applications where access to hazardous machine areas must remain restricted until the required safe condition has been achieved.
The NG 2D1D411E-F31 is supplied complete with the VN NG-F31 high-coding-level actuator. The switch incorporates two safety inputs, two safety outputs, actuator-inserted and actuator-locked signalling outputs, solenoid activation inputs and an actuator programming/reset input, while two integrated pushbuttons provide convenient local machine-control functionality.
Key Advantages
- Combines guard monitoring, guard locking and integrated control devices in one unit.
- Supplied complete with a VN NG-F31 high-coding-level actuator.
- D working method keeps the actuator locked with the solenoid de-energised.
- Two safety inputs and two safety outputs OS1-OS2 support integration into machine safety systems.
- Separate signalling outputs indicate actuator inserted and actuator locked conditions.
- Two integrated pushbuttons reduce the need for separate operator-control devices around the guard.
- Durable metal housing with three threaded M20 × 1.5 conduit entries.
- Rotating head provides installation flexibility on industrial machinery.

Integrated Guard Locking and Safety Monitoring
Safety switches with guard locking are used where opening a machine guard before hazardous movement or processes have reached a safe condition could expose personnel to risk. The Pizzato NG series combines coded actuator detection, guard locking and electronic safety outputs to provide reliable monitoring of safety guards in automated machinery.
On the NG 2D1D411E-F31, the OS1-OS2 safety outputs become active when the actuator is inserted and locked. Dedicated O3 and O4 signalling outputs provide separate actuator-inserted and actuator-locked status information, while the integrated white and black pushbuttons allow local operator commands to be incorporated directly into the guard-locking assembly.
Typical Applications
- Industrial machine guard doors and access gates.
- Automated manufacturing and assembly machinery.
- Robotic cells and safeguarded production areas.
- Packaging and processing machinery.
- Material handling and conveyor systems.
- Machine tools and automated production equipment.
- Applications requiring guard locking with integrated operator controls.
