Why Choose the Pizzato NG 2D1D411E Safety Switch with Lock?
The Pizzato NG 2D1D411E is an advanced NG series safety switch with guard locking and integrated control devices, designed for monitoring and locking movable guards, doors and access points on industrial machinery. Its combination of electronic safety monitoring, robust metal construction and integrated operator controls makes it particularly suitable for modern automated machinery and safety-related control systems.
The switch uses Pizzato's D working method, with the actuator locked when the solenoid is de-energised. Its OS1-OS2 safety outputs use activation mode 1 and become active when an actuator is inserted and locked, supporting applications where a machine guard must remain secured until the required safe condition has been achieved.
The NG 2D1D411E incorporates two safety inputs, two safety outputs and separate actuator-status signalling outputs, together with solenoid activation and actuator programming/reset inputs. Two integrated pushbuttons provide convenient local operator-control functionality, while the rotating head and three M20 × 1.5 threaded conduit entries provide flexibility when installing the switch on industrial equipment. This version is supplied without an actuator and without a connector.
Key Advantages
- Combines guard monitoring, guard locking and integrated control devices in one assembly.
- D working method locks the actuator with the solenoid de-energised.
- Two safety inputs and two OS1-OS2 safety outputs for integration with safety-related control systems.
- Separate outputs provide actuator-inserted and actuator-locked status signalling.
- Two integrated pushbuttons reduce the requirement for separate operator-control devices around the guard.
- Robust metal housing designed for industrial machine applications.
- Rotating head provides flexibility when positioning the switch around machine guards.
- Three M20 × 1.5 threaded conduit entries support flexible field wiring.

Integrated Guard Locking and Safety Monitoring
Safety switches with guard locking are used where access to hazardous machinery must remain restricted until the machine or process has reached the required safe condition. The Pizzato NG series combines electronic guard monitoring with an electromechanical locking system, allowing the position and locking condition of a machine guard to be incorporated into a safety-related control system.
On the NG 2D1D411E, the OS1-OS2 safety outputs become active when the actuator is inserted and locked. Dedicated O3 and O4 signalling outputs provide separate information about actuator insertion and locking status, while the integrated white and black pushbuttons allow local operator commands to be incorporated directly into the safety-switch assembly.
Typical Applications
- Industrial machine guard doors and access gates.
- Automated manufacturing and assembly machinery.
- Robotic cells and safeguarded production areas.
- Packaging and processing machinery.
- Material handling and conveyor systems.
- Machine tools and automated production equipment.
- Applications requiring guard locking with integrated operator controls.
