Why Choose the Pizzato NG 2D7D312K-F31 Safety Switch with Lock?
The Pizzato NG 2D7D312K-F31 is an industrial safety switch with guard locking and integrated control devices designed for monitoring and controlling access to hazardous areas of machinery. As part of the advanced Pizzato NG series, it combines coded actuator detection, guard locking, safety outputs and operator controls within a robust metal-bodied device.
This model uses principle D operation, with the actuator locked when the electromagnet is de-energised. It incorporates two safe inputs, two safe outputs and dedicated signalling outputs for actuator insertion and locking status, supporting integration into modern machine safety control systems. A status indication function, auxiliary release and emergency release further enhance usability in demanding industrial applications.
The NG 2D7D312K-F31 is supplied complete with the VN NG-F31 high-level coded actuator. Its orientable head incorporates a panic release, while the metal enclosure provides three threaded M20 × 1.5 cable entries. Two integrated control devices provide convenient local machine control directly at the guard access point.

Reliable Guard Locking for Industrial Machinery
Guard-locking safety switches help prevent access to hazardous machine areas until the safety control system permits the guard to be opened. The Pizzato NG series combines coded actuator monitoring with electronically controlled safety functions, allowing guard position and locking status to be incorporated into a machine's safety-related control architecture.
The NG 2D7D312K-F31 further combines these safety functions with local pushbutton controls. Its de-energised locking principle is particularly useful where the guard must remain mechanically locked if power to the locking electromagnet is removed, while the integrated panic and auxiliary release functions provide additional access-management capabilities.
Typical Applications
- Machine guard doors and access gates.
- Automated production and assembly machinery.
- Packaging and processing equipment.
- Robotic cells and automated manufacturing systems.
- Conveyors and material handling installations.
- Machining centres and industrial machine tools.
- Safety enclosures requiring local operator controls.
