Why Choose the Pizzato NG 2D7D41AP-F31 Safety Switch with Lock?
The Pizzato NG 2D7D41AP-F31 is an advanced NG series safety switch with guard locking and integrated control devices, designed for reliable monitoring and locking of movable guards, doors and access points on industrial machinery. Supplied complete with the VN NG-F31 high-coding-level actuator, it combines coded actuator detection, electronic safety outputs, guard locking and local operator controls within one robust device.
This NG series configuration features a rotating head with escape pushbutton and operates according to the D working principle, meaning the actuator remains locked while the electromagnet is de-energised. Two safe inputs and two safe outputs provide integration with compatible safety controllers and safety PLCs, while dedicated signalling outputs indicate actuator insertion and locking status.
The NG 2D7D41AP-F31 incorporates a three-device cover configuration and a durable metal housing with three threaded M20×1.5 cable entries. Its IP65 protection rating according to EN 60529, high-coded actuator and integrated escape-release facility make it a versatile solution for demanding machine-safety installations where controlled access and local operator functionality are required.

Reliable Guard Locking for Industrial Machinery
Safety switches with guard locking are designed to keep access guards closed when hazardous machine conditions remain present. The Pizzato NG series combines electronic actuator detection with controlled locking and safety outputs, allowing a machine safety system to monitor both the position of the guard and whether the actuator is securely locked.
The NG 2D7D41AP-F31 extends this functionality by incorporating three control-device positions and an escape pushbutton into the switch assembly. Its high-coded actuator helps increase resistance to interlock bypassing, while the dedicated status outputs provide useful information to the machine-control system for diagnostics and process management.
Typical Applications
- Automated production machinery and manufacturing cells.
- Robotic cells and perimeter guarding systems.
- Packaging and processing machinery.
- Machine-tool access doors and protective enclosures.
- Conveyor and material-handling systems.
- Automated assembly and production lines.
- Guarded areas requiring an internal escape-release facility.
- Industrial machinery requiring integrated local operator controls.
