Why Choose the Pizzato NG 2D7D511A-F31 Safety Switch with Lock?
The Pizzato NG 2D7D511A-F31 is a high-performance NG series safety switch with guard locking designed for reliable monitoring and controlled locking of movable guards, access doors and protective enclosures on industrial machinery. Supplied complete with the VN NG-F31 high-coding-level actuator, it uses RFID technology to provide dependable coded actuator recognition for safety-related machine applications.
The NG 2D7D511A-F31 uses the D working principle, in which the actuator remains locked while the electromagnet is de-energised. It provides two safe inputs and two safe outputs together with dedicated signalling outputs for actuator-inserted and actuator-locked status, enabling effective integration with compatible safety controllers and safety PLCs.
Designed for demanding industrial installations, the switch has a metal housing with three M20×1.5 threaded cable entries, a rotating head with escape pushbutton and a high locking force of 9750 N. Protection to IP67 according to EN 60529 and IP69K according to ISO 20653 supports reliable operation in harsh machine environments.

Reliable Guard Locking for Industrial Machinery
Guard-locking safety switches are particularly important on machines where hazardous conditions can remain after a stop command, such as equipment with rotating components, mechanical inertia, pressure or elevated temperatures. The Pizzato NG 2D7D511A-F31 allows the protective guard to remain locked until the machine safety system determines that access can be permitted.
Its RFID actuator recognition, high locking force and electronic safety architecture provide a robust solution for modern machine builders. The two safety inputs and outputs also support connection with other compatible safety devices, while dedicated status and EDM signals provide useful information for machine-control and diagnostic functions.
Typical Applications
- Automated production machinery and manufacturing cells.
- Robotic cells and perimeter guarding systems.
- Packaging and processing machinery.
- Machine tools with hazardous run-down movement.
- Conveyor and material-handling equipment.
- Automated assembly and production lines.
- Guards protecting rotating or high-inertia machinery.
- Industrial equipment requiring high-force controlled guard locking.
