Why Choose the Pizzato NG 2D6D421E-F31 Safety Switch with Lock?
The Pizzato NG 2D6D421E-F31 is an advanced NG series safety switch with guard locking and integrated control devices, supplied with the VN NG-F31 high-level coded actuator. Designed for industrial machine guarding, it combines electronic actuator detection, monitored guard locking and local operator controls in one robust assembly for doors, gates and other safety-critical access points.
This configuration incorporates two integrated control devices, providing operator functions directly at the guarded access point. By combining local controls with the safety interlock, the NG 2D6D421E-F31 provides machine builders and automation engineers with a compact solution for machinery where reliable access monitoring and convenient operator interaction are required.
The NG 2D6D421E-F31 uses Principle D operation, meaning the actuator remains locked when the solenoid is de-energised. Its Mode 2 safety-output configuration activates the OS safety outputs when the actuator is inserted, while dedicated O3 and O4 signalling outputs provide separate indication of actuator-inserted and actuator-locked conditions.
Key Advantages
- Combines guard locking, electronic safety monitoring and integrated operator controls in one assembly.
- Supplied complete with the VN NG-F31 high-level coded actuator.
- High-level actuator coding helps protect against inappropriate actuator substitution.
- Principle D operation keeps the actuator locked with the solenoid de-energised.
- Mode 2 safety logic activates the safety outputs when the actuator is inserted.
- Dual safety inputs and dual safety outputs support integration with compatible safety controllers.
- Dedicated signalling outputs separately indicate actuator inserted and actuator locked.
- Integrated controls provide convenient operator functions directly at the machine guard.
- Robust metal construction is designed for demanding industrial automation environments.

Reliable Guard Locking with Electronic Safety Monitoring
The Pizzato NG 2D6D421E-F31 is designed for machinery where access through a movable protective guard must be reliably monitored and controlled. Its 9,750 N maximum locking force provides robust guard retention, while Principle D operation maintains the locked condition when the solenoid is de-energised.
Mode 2 safety logic allows the OS1-OS2 safety outputs to become active when the actuator is inserted, while O3 and O4 provide independent information about actuator presence and locking status. Combined with the high-level coded VN NG-F31 actuator, integrated controls and auxiliary and escape-release functionality, the switch provides a versatile safety solution for sophisticated automated machinery.
Typical Applications
- Industrial machine guard doors and safety gates.
- Robotic cells and automated manufacturing systems.
- Packaging and processing machinery.
- Automated assembly and production lines.
- Material handling and conveyor equipment.
- Machine tools and manufacturing centres.
- Guarded machinery requiring integrated local operator controls.
- Safety-critical access points requiring monitored guard locking.
