Why Choose the Pizzato NG 2D7D411H Safety Switch with Lock?
The Pizzato NG 2D7D411H is an industrial NG series safety switch with guard locking and an integrated control device designed for monitoring movable guards and controlling access to hazardous areas of machinery. It combines coded electronic guard monitoring, solenoid-operated locking, safety inputs and outputs, status signalling and local operator control within a robust metal housing.
This NG configuration uses principle D operation, meaning the actuator is locked when the locking solenoid is de-energised. The switch architecture provides two safety inputs IS1–IS2, two safety outputs OS1–OS2 and dedicated signalling outputs for actuator-inserted and actuator-locked status, allowing straightforward integration with modern safety controllers and automated machinery.
The NG 2D7D411H incorporates a single white pushbutton with 1NO + 1NC contacts. Its metal housing provides three threaded M20 × 1.5 conduit entries, while the rotating head incorporates an escape pushbutton for additional personnel-release functionality within guarded machine areas.
Key Advantages
- Combines guard monitoring, guard locking and local operator control in one device.

Reliable Guard Locking for Industrial Machinery
Guard-locking safety switches are used where a protective guard must remain closed until hazardous machine conditions have ended. The Pizzato NG platform combines electronic actuator monitoring with mechanical guard retention, enabling the machine safety system to supervise both guard position and locking status before allowing machinery to operate or personnel to gain access.
The de-energised locking principle of the NG 2D7D411H is particularly useful where a guard should remain retained when power to the locking solenoid is removed. Its integrated pushbutton provides a convenient local operator command, while the rotating head and escape pushbutton support flexible installation and personnel-release requirements around guarded machinery.
Typical Applications
- Machine guard doors and safety access gates.
- Robotic cells and automated manufacturing systems.
- Packaging and processing machinery.
- Machine tools with hazardous run-down times.
- Conveyor and material handling systems.
- Automated assembly and production equipment.
- Guarded machinery requiring an integrated local control pushbutton.
