NG 2D1D321H-F31 Pizzato NG series safety switch with lock and integrated control devices, with actuator

Why Choose the Pizzato NG2D1D321H-F31 Safety Switch with Lock?

The Pizzato NG2D1D321H-F31 is an advanced NG series safety switch with guard locking and an integrated control device, designed for monitoring and securing movable guards, doors and access points on industrial machinery. It combines electronic safety monitoring, a robust locking mechanism and a local operator control within one metal-bodied device, helping simplify machine guarding installations.

This configuration uses Pizzato's D working method, meaning the actuator is locked when the solenoid is de-energised. It provides two safety inputs IS1-IS2, two safety outputs OS1-OS2, dedicated signalling outputs for actuator-inserted and actuator-locked status, solenoid activation inputs and an I3 reset input for integration with industrial safety control systems.

The NG2D1D321H-F31 features an integrated white 1NO+1NC pushbutton and uses activation mode 2, in which the safety outputs become active when the actuator is inserted. It is supplied complete with the VN NG-F31 high-coding-level actuator, while its rotating head, metal housing and three M20 × 1.5 threaded conduit entries provide a robust and flexible solution for industrial machine guarding.

Key Advantages

• Combines electronic guard monitoring, guard locking and an operator control in one device.
• D working method keeps the actuator locked with the solenoid de-energised.
• High-coding-level VN NG-F31 actuator supports enhanced protection against inappropriate actuator substitution.
• Integrated white 1NO+1NC pushbutton provides a convenient local machine-control function.
• Two safety inputs and two safety outputs enable integration with compatible machine safety controllers.
• Dedicated signalling outputs provide separate actuator inserted and actuator locked status information.

Reliable Guard Locking and Safety Monitoring

The Pizzato NG2D1D321H-F31 provides electronic monitoring of the actuator together with electrically controlled guard locking. Its separate signalling outputs allow the control system to distinguish between an actuator that has been inserted and one that is mechanically locked, providing useful status information for machine sequencing and safety-system diagnostics.

With activation mode 2, the OS1-OS2 safety outputs become active when the actuator is inserted, while the separate O4 output reports the locking condition. The de-energised-solenoid locking principle and high-coding-level actuator make this configuration particularly suitable for industrial access points requiring robust guard retention, coded actuator detection and local operator control.

Typical Applications

• Machine guard doors and access panels.
• Robotic cells and automated production systems.
• Packaging and processing machinery.
• Machine tools and machining centres.
• Assembly and manufacturing equipment.
• Guarded conveyor and material handling systems.
• Industrial access points requiring guard locking and local operator control.
