Why Choose the Pizzato NG 2D5D416B-F31 Safety Switch with Lock?
The Pizzato NG 2D5D416B-F31 is an advanced NG series safety switch with guard locking and integrated control devices, supplied complete with a high-coded actuator. Designed for industrial machine guarding, it combines electronic safety monitoring, electromagnetic guard locking and local operator controls within a robust metal housing.
This configuration uses the D working principle, meaning the actuator is locked while the locking electromagnet is de-energised. Its Mode 1 safety logic activates the OS1 and OS2 safety outputs when the actuator is inserted and locked, while dedicated O3 and O4 signalling outputs provide actuator-inserted and actuator-locked status information.
The NG 2D5D416B-F31 incorporates a green pushbutton with 1NO + 1NC contacts, a blanking plug in the second control position and a red emergency-stop pushbutton with turn-to-release action and 2NC contacts. It also features an orientable head with auxiliary key release and is supplied with the VN NG-F31 high-coding-level actuator.

Guard Monitoring with De-Energised Locking and Integrated Emergency Stop
The Pizzato NG 2D5D416B-F31 combines electronic actuator monitoring with electromagnetic guard locking so that a machine-safety system can supervise a movable guard while controlling access to hazardous areas. Its D working principle retains the actuator while the locking electromagnet is de-energised, and Mode 1 logic activates the OS1 and OS2 safety outputs when the actuator is both inserted and locked.
The orientable head incorporates an auxiliary key release for manual unlocking when required by the machine design. Combined with the VN NG-F31 high-coded actuator, integrated green pushbutton, red emergency-stop control and independent actuator-status outputs, this configuration provides a comprehensive guard-access and operator-control solution for automated industrial machinery.
Typical Applications
- Industrial machine guard doors and access panels.
- Robotic cells and automated manufacturing systems.
- Packaging and processing machinery.
- Automated assembly and production lines.
- Conveyor and material-handling systems.
- Machine tools and production equipment.
- Guarding systems requiring de-energised electromagnetic locking.
- Machinery requiring auxiliary key-release functionality.
- Applications requiring integrated local operator and emergency-stop controls.
- Machine-safety systems requiring a high-coding-level actuator.
