Why Choose the Pizzato NG 2D7D412N-F31 Safety Switch with Lock?
The Pizzato NG 2D7D412N-F31 is an NG series safety switch with guard locking and integrated control devices, designed for safety monitoring of movable machine guards and controlled access to hazardous areas. It combines electronic guard monitoring, a high-force locking mechanism and local operator-control functionality in a robust metal housing for industrial machinery and automated equipment.
This configuration uses the D working principle, meaning the actuator remains locked when the electromagnet is de-energised. It provides two safety inputs IS1–IS2, two safety outputs OS1–OS2 and separate O3 and O4 signalling outputs for actuator-inserted and actuator-locked status, together with inputs for electromagnet activation and actuator programming/reset.
The NG 2D7D412N-F31 provides a locking force of 9750 N and operates in Mode 1, with the safety outputs active when the actuator is inserted and locked. It is supplied complete with the VN NG-F31 high-coding-level actuator and incorporates an orientable head with an anti-panic escape pushbutton for applications requiring an internal emergency release facility.
Key Advantages
- Combines guard monitoring, guard locking and integrated control devices in one industrial safety assembly.
- 9750 N locking force provides robust retention of guarded machine access points.
- VN NG-F31 high-coding-level actuator helps protect against inappropriate actuator substitution.
- D working principle keeps the actuator locked while the electromagnet is de-energised.
- Two safety inputs and two electronic safety outputs support integration with suitable machine safety systems.
- Separate O3 and O4 signalling outputs provide actuator-presence and locking-status information.
- Orientable head with anti-panic escape pushbutton provides an internal emergency release facility.
- Metal housing with three M20 × 1.5 cable entries provides a robust installation platform.

High-Force Guard Locking with Integrated Machine Controls
The Pizzato NG 2D7D412N-F31 is intended for machinery where a movable guard must remain secured while hazardous conditions are present. Its D working principle keeps the actuator locked with the electromagnet de-energised, while Mode 1 operation requires the actuator to be inserted and locked before the OS1 and OS2 safety outputs become active.
The integrated-control configuration allows local machine-control functions to be incorporated into the guard-locking assembly, while the supplied VN NG-F31 actuator provides a high coding level. Separate O3 and O4 outputs communicate actuator-presence and locking status, supporting diagnostics and integration with the wider machine-control architecture.
Typical Applications
- Industrial machine safety doors and movable guards.
- Robotic cells and automated production areas.
- Packaging and processing machinery.
- Machine tools with hazardous residual movement.
- Automated assembly and manufacturing equipment.
- Conveyor and material handling systems.
- Guarded areas requiring an internal anti-panic release.
- OEM machinery requiring guard locking and integrated local controls.
