Why Choose the Pizzato NG 2D7E311C-F31 Safety Switch with Lock?
The Pizzato NG 2D7E311C-F31 is an industrial NG series safety switch with guard locking and integrated control devices designed for monitoring protected machine access points while providing local operator controls. Its electronic safety architecture combines coded actuator recognition, monitored guard locking and safety outputs within a robust metal-bodied device.
This configuration incorporates three control devices: a white pushbutton with 1NO+1NC contacts, a yellow pushbutton with 1NO+1NC contacts and a red emergency-stop pushbutton with turn-to-release operation and 2NC contacts. This allows common operator and emergency functions to be positioned directly at the guarded access point, reducing the need for separate control enclosures.
The NG 2D7E311C-F31 uses the E working principle, with the actuator locked when the electromagnet is energised. It is supplied with the VN NG-F31 high-level coded actuator, features a rotating head with escape pushbutton and provides a maximum holding force of 9750 N, making it suitable for demanding industrial machine-guarding applications.
Key Advantages
- Combines guard monitoring, guard locking and three operator control devices in one assembly.
- Supplied complete with a VN NG-F31 high-level coded actuator.
- Provides a maximum guard-locking holding force of 9750 N.

Integrated Guard Locking and Local Machine Control
The Pizzato NG 2D7E311C-F31 combines RFID actuator recognition with electronically monitored guard locking and local operator controls. Its Mode 1 configuration activates the OS1 and OS2 safety outputs when the actuator is inserted and locked, while separate O3 and O4 signalling outputs provide information about actuator insertion and locking status to the machine control system.
The three-device cover places two control pushbuttons and an emergency-stop control directly at the protected access point. Together with its 9750 N holding force, E working principle and escape-release head, this integrated arrangement makes the NG 2D7E311C-F31 well suited to machinery requiring guard locking, local control and emergency functionality within a single assembly.
Typical Applications
- Industrial machine safety doors and movable guards.
- Robotic cells and automated manufacturing systems.
- Packaging and processing machinery.
- Material handling and conveyor installations.
- Assembly and production equipment.
- Machine tools and protected manufacturing cells.
- Guarded machinery requiring integrated local controls and emergency-stop functionality.
