Why Choose the Pizzato NG 2D6D421C-F31 Safety Switch with Lock?
The Pizzato NG 2D6D421C-F31 is an advanced NG series safety switch with guard locking and integrated control devices, supplied complete with the VN NG-F31 high-level coded actuator. Designed for industrial machine guarding, it combines electronic safety monitoring, controlled guard locking and local operator controls in one robust metal assembly.
This exact configuration incorporates three integrated control devices: a white pushbutton with 1NO+1NC contacts, a yellow pushbutton with 1NO+1NC contacts and a red emergency-stop pushbutton with rotational release and 2NC contacts. This allows important operator functions to be positioned directly alongside the guarded access point, providing a compact solution for automated machinery and production equipment.
The NG 2D6D421C-F31 uses Principle D operation, with the actuator locked when the electromagnet is de-energised. Its Mode 2 safety-output configuration activates the OS safety outputs when the actuator is inserted. Dedicated O3 and O4 signalling outputs separately indicate actuator-inserted and actuator-locked conditions, supporting detailed machine-status monitoring.
Key Advantages
- Combines guard locking, electronic safety monitoring and three integrated control devices in one assembly.
- Supplied complete with the VN NG-F31 high-level coded actuator.
- Integrated white and yellow pushbuttons provide convenient local operator functions.

Reliable Guard Locking with Integrated Machine Controls
The Pizzato NG 2D6D421C-F31 provides a comprehensive solution for machinery where a movable protective guard must be monitored and locked while operator controls are required directly at the access point. Its robust locking mechanism provides up to 9,750 N holding force, while Principle D operation maintains the locked condition when the electromagnet is de-energised.
The switch's Mode 2 electronic safety architecture activates OS1-OS2 when the actuator is inserted, while O3 and O4 provide separate signalling for actuator insertion and confirmed locking. Combined with the high-level coded VN NG-F31 actuator, three integrated controls, auxiliary release and anti-panic function, this makes the NG 2D6D421C-F31 particularly suitable for sophisticated automated machinery and guarded production systems.
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 an integrated emergency-stop function.
