Why Choose the Pizzato NG 2D1D412V-F31 Safety Switch with Lock?
The Pizzato NG 2D1D412V-F31 is an advanced NG series safety switch with guard locking and integrated control devices, designed for monitoring and securing movable guards, doors and access points on industrial machinery. It combines electronic safety monitoring, robust guard locking and local operator-control functionality within a durable industrial safety-switch assembly.
The switch uses Pizzato's D working method, in which the actuator is locked when the solenoid is de-energised. Its two OS1-OS2 safety outputs use activation mode 1 and become active when the actuator is inserted and locked, making the device suitable for machinery where guarded access must remain restricted until the required safe condition has been achieved.
The NG 2D1D412V-F31 is supplied complete with the VN NG-F31 high-coding-level actuator. Its integrated controls comprise a white 1NO + 1NC pushbutton, a blue 1NC + 1NO pushbutton and a red turn-to-release emergency stop button with 2NC contacts, combining guard monitoring, locking and operator functions in one convenient assembly.
Key Advantages

Integrated Guard Locking and High-Coding-Level Safety Monitoring
Safety switches with guard locking are used where access to hazardous machinery must remain restricted until the machine or process has reached the required safe condition. The Pizzato NG series combines coded electronic actuator detection with electromechanical guard locking, allowing both guard position and locking status to be incorporated into the machine's safety-related control system.
The NG 2D1D412V-F31 combines this guard-monitoring technology with three local operator controls. The white and blue pushbuttons can provide machine-control commands, while the red turn-to-release emergency stop button provides 2NC contacts for emergency-stop functionality. The F31 actuator provides a high coding level for applications requiring enhanced protection against actuator substitution.
Typical Applications
- Industrial machine guard doors and access gates.
- Robotic cells and safeguarded automation areas.
- Automated manufacturing and assembly machinery.
- Packaging and processing equipment.
- Material handling and conveyor systems.
- Machine tools and automated production equipment.
- Production cells requiring local emergency-stop functionality.
- Applications requiring high-coding-level guard monitoring and integrated operator controls.
