Why Choose the Pizzato NG 2D1D419P-F31 Safety Switch?
The Pizzato NG 2D1D419P-F31 is an advanced NG series safety switch with lock and integrated control devices, designed for reliable monitoring and locking of movable guards, doors and protected access points on industrial machinery. It combines electronic safety monitoring, guard locking and local operator controls within one robust assembly, making it particularly suitable for sophisticated machine safety and factory automation systems.
This NG configuration uses the D working principle, with the actuator locked while the electromagnet is de-energised. It provides two IS1–IS2 safety inputs and two OS1–OS2 safety outputs, together with dedicated O3 and O4 signalling outputs for actuator-inserted and actuator-locked status. The safety outputs operate in Mode 1, becoming active when the actuator is inserted and locked.
The NG 2D1D419P-F31 incorporates three operator devices: a white 1NO pushbutton, a blue 1NO pushbutton and a red emergency-stop pushbutton with rotational release and 2NC + 1NO contacts. Its metal housing has three threaded M20 × 1.5 cable entries and an orientable head, while the supplied VN NG-F31 high-level coded actuator supports dependable guard identification in demanding safety applications.

Reliable Guard Locking and Local Control for Industrial Machinery
Guard-locking safety switches are used where a movable protective guard must remain secured until hazardous machine conditions have ended. The Pizzato NG 2D1D419P-F31 monitors both actuator insertion and locking status, allowing a suitable safety-related control system to verify the condition of the guard before hazardous machine operation is permitted.
The integrated pushbuttons and emergency-stop device provide local operator functions directly at the guarded access point, reducing the need for separate control enclosures in suitable installations. Combined with its high-level coded actuator, metal housing and electronic safety outputs, the NG 2D1D419P-F31 provides a comprehensive solution for machine guarding, access control and operator interaction.
Typical Applications
- Machine guard doors and movable protective guards.
- Robotic cells and automated manufacturing systems.
- Packaging and processing machinery.
- Automated production and assembly equipment.
- Conveyor and material handling systems.
- Machinery requiring local emergency-stop and operator-control functions.
- OEM machinery and factory automation installations.
