Why Choose the Pizzato NG 2D7D411H-LP60 Safety Switch with Lock?
The Pizzato NG 2D7D411H-LP60 is an industrial NG series safety switch with guard locking and integrated control devices designed for monitoring movable guards and controlling access to hazardous machine areas. It combines coded electronic guard monitoring, solenoid-operated locking, safety inputs and outputs and local operator control functionality within a robust metal-bodied assembly.
This NG series configuration uses principle D operation, in which the actuator is retained when the locking solenoid is de-energised. The platform provides two safe inputs IS1–IS2, two safe outputs OS1–OS2 and dedicated signalling outputs for actuator-inserted and actuator-locked status, supporting straightforward integration with modern safety controllers and machine automation systems.
The NG 2D7D411H-LP60 features a single integrated white pushbutton with 1NO + 1NC contacts. Its metal housing has three threaded M20 × 1.5 cable entries, while the rotating head incorporates an escape pushbutton to provide an additional means of release from inside a protected machine area.
Key Advantages
- Combines guard monitoring, guard locking and local operator control in one safety device.
- Principle D locking operation retains the actuator with the locking solenoid de-energised.
- Provides 2 safe inputs and 2 safe outputs for safety-related control-system integration.
- Dedicated outputs signal actuator inserted and actuator locked conditions.
- Integrated white 1NO + 1NC pushbutton provides convenient local machine control.
- Robust metal housing with three M20 × 1.5 threaded cable entries.
- Rotating head with escape pushbutton supports safer access to guarded machinery.

Reliable Guard Locking for Industrial Machinery
Guard-locking safety switches are used where opening a protective guard before hazardous machine conditions have ended could expose personnel to risk. The Pizzato NG platform combines electronic actuator monitoring with mechanical guard retention, allowing the machine safety system to supervise both guard position and locking status.
The de-energised locking principle used by the NG 2D7D411H-LP60 is suited to applications where the guard must remain mechanically retained when the locking solenoid is not energised. Its integrated pushbutton can provide a convenient local operator command, while the escape pushbutton offers an additional release function for personnel inside guarded areas.
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 installations.
- Automated assembly and production equipment.
- Guarded machine areas requiring an integrated local pushbutton.
