Why Choose the Pizzato NG 2D6D321C-F31 Safety Switch with Lock?
The Pizzato NG 2D6D321C-F31 is a robust NG series safety switch with guard locking and integrated control devices, supplied complete with a high-coded actuator for industrial machine guarding applications. Designed to combine guard monitoring, guard locking and operator controls in one assembly, it provides a practical safety solution for machinery where controlled access to hazardous areas is required.
This configuration features 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 essential machine-control and emergency-stop functions to be positioned directly alongside the guard-locking device, helping simplify operator interfaces and machine installation.
The NG 2D6D321C-F31 uses Principle D locking, meaning the actuator remains locked while the electromagnet is de-energised. It provides two safe inputs IS1-IS2, two safe outputs OS1-OS2 and dedicated signalling outputs for actuator-inserted and actuator-locked status. The switch is supplied with the VN NG-F31 high-coded actuator and incorporates an orientable head with key release and anti-panic escape release.
Key Advantages
- Combines guard locking, safety monitoring and operator controls in one industrial device.
- Supplied with a VN NG-F31 high-coded actuator for secure guard detection.
- High 9,750 N locking force for demanding machine-guard applications.

Reliable Guard Locking with Integrated Operator Control
Safety switches with guard locking are used where hazardous machine movement requires a protective guard to remain closed and locked during operation. The Pizzato NG series combines coded actuator monitoring and electronic safety outputs with a robust mechanical locking system, allowing the machine safety circuit to monitor guard status and control access to hazardous areas.
By integrating two operator pushbuttons and an emergency-stop control into the same assembly, the NG 2D6D321C-F31 can also reduce the need for separate control stations around guarded machinery. Its high locking force, coded actuator, dedicated status outputs and escape-release facilities make it particularly suitable for automated production equipment and safety-critical access points.
Typical Applications
- Industrial machine guard doors and access gates.
- Robotic cells and automated production lines.
- Packaging and processing machinery.
- Material handling and conveyor systems.
- Machine tools and manufacturing equipment.
- Guarded machinery requiring local operator pushbuttons.
- Safety access points requiring integrated emergency-stop control.
