Why Choose the Pizzato NG 2D7E418Z-F31 Safety Switch with Lock?
The Pizzato NG 2D7E418Z-F31 is an advanced safety switch with guard locking and integrated control devices designed for monitoring and securing movable guards, doors and access points on industrial machinery. Part of the Pizzato NG series, it combines coded actuator detection, monitored guard locking and operator controls within a robust metal housing.
This configuration incorporates three integrated control devices: a white 1NO + 1NC pushbutton, a black 1NO + 1NC pushbutton and a red emergency pushbutton with turn-to-release action and 2NC contacts. Two safety inputs and two safety outputs support integration with modern machine safety systems, while dedicated signalling outputs provide actuator-inserted and actuator-locked status information.
The NG 2D7E418Z-F31 uses the D working method, meaning the actuator is locked with the solenoid de-energised. It is supplied complete with the VN NG-F31 high-level coded actuator and uses a 19-pin M23 connector, providing a comprehensive guard-locking and local-control solution for demanding automated machinery.

Reliable Guard Locking and Local Machine Control
Guard-locking safety switches are used where a protective guard must remain secured while hazardous machine movement or processes are present. The Pizzato NG series combines coded actuator monitoring with controlled locking, allowing the safety system to supervise whether the guard actuator is inserted and whether it is securely locked before permitting appropriate machine operation.
The NG 2D7E418Z-F31 further integrates two standard pushbuttons and a red emergency pushbutton directly into the switch assembly. This arrangement can reduce the need for separate operator-control enclosures at guarded access points while providing safety outputs, status signalling and guard-lock control through a single machine-safety device.
Typical Applications
- Industrial machine guard doors and access gates.
- Robotic cells and automated manufacturing systems.
- Packaging and processing machinery.
- Machine tools and production equipment.
- Automated assembly and manufacturing lines.
- Conveyor and material handling systems.
- Guarded access points requiring local pushbutton and emergency-control functions.
