Why Choose the Pizzato NG 2D7D411L-F31 Safety Switch with Lock?
The Pizzato NG 2D7D411L-F31 is an NG series safety switch with guard locking and three integrated control devices, designed to combine machine guard monitoring, controlled access and local operator functions in one robust assembly. Its integrated controls comprise a green pushbutton, a red pushbutton and a red emergency-stop pushbutton, making it particularly suitable for guarded machinery where operational and emergency controls are required directly at the access point.
The switch uses the D working principle, with the actuator locked when the electromagnet is de-energised. It provides two safety inputs IS1–IS2, two electronic safety outputs OS1–OS2 and separate O3 and O4 signalling outputs for actuator-inserted and actuator-locked status. Mode 1 operation means the safety outputs are active when the actuator is inserted and locked.
With a 9750 N locking force, metal housing, three threaded M20 × 1.5 conduit entries and an orientable head with anti-panic escape pushbutton, the NG 2D7D411L-F31 is engineered for demanding industrial guarding applications. It is supplied complete with the VN NG-F31 high-coding-level actuator for enhanced protection against inappropriate actuator substitution.
Key Advantages
- Combines guard locking, safety monitoring and three operator-control devices in one assembly.
- 9750 N locking force provides strong retention of guarded machine access points.
- Integrated green and red pushbuttons provide convenient local machine-control functions.
- Integrated red emergency-stop pushbutton with rotary release and 2NC contacts provides an emergency control directly at the guard.
- VN NG-F31 high-coding-level actuator supports enhanced protection against foreseeable manipulation.
- D working principle keeps the actuator locked when the electromagnet is de-energised.
- Separate signalling outputs provide actuator-presence and locking-status information.
- Orientable head with anti-panic escape pushbutton supports emergency egress from inside a guarded area.

Guard Locking with Integrated Operator and Emergency Controls
The Pizzato NG 2D7D411L-F31 provides a compact way to combine safety-related guard locking with the controls needed at a guarded machine access point. Its green and red 1NO+1NC pushbuttons can support local machine commands, while the red 2NC emergency-stop pushbutton provides an immediately accessible emergency control without requiring a separate control enclosure.
Mode 1 operation requires the actuator to be inserted and locked for the OS1 and OS2 safety outputs to become active. Separate O3 and O4 outputs provide information on actuator presence and locking status, while the high-coding-level VN NG-F31 actuator helps reduce the possibility of defeating the interlocking function through substitution with another actuator.
Typical Applications
- Industrial machine safety doors and movable guards.
- Robotic cells and automated production areas.
- Packaging and processing machinery.
- Automated assembly and manufacturing equipment.
- Machine tools with guarded hazardous areas.
- Conveyor and material handling systems.
- Guarded work areas requiring local emergency-stop functionality.
- OEM machinery requiring integrated operator controls and guard locking.
