Why Choose the Pizzato NG 2D1D411A Safety Switch with Lock?
The Pizzato NG 2D1D411A is an advanced NG series RFID safety switch with solenoid guard locking designed for monitoring and securing guards, doors and access points on industrial machinery. It combines non-contact RFID actuator detection with high-strength mechanical locking and electronic safety outputs, providing dependable guard monitoring for modern automated equipment and machine safety systems.
The NG 2D1D411A uses the D working method, meaning the actuator remains mechanically locked when the solenoid is de-energised. Its Mode 1 safety configuration activates the OS1 and OS2 safety outputs only when a compatible actuator has been correctly inserted and locked, making the switch particularly suitable for machinery where access must remain prevented until hazardous movement or processes have stopped.
This base NG 2D1D411A configuration is supplied without an actuator and without a connector, allowing the appropriate NG actuator and connection arrangement to be selected separately for the installation. The switch features a robust metal housing, rotating head, three M20 × 1.5 threaded conduit entries and IP67 / IP69K environmental protection for demanding industrial applications.
Key Advantages
- Advanced RFID safety switch with solenoid guard locking.

Reliable RFID Guard Locking for Industrial Machine Safety
Guard-locking safety switches are used where opening a machine guard before hazardous movement or processes have stopped could expose personnel to risk. The Pizzato NG 2D1D411A combines electronic RFID actuator monitoring with mechanical guard locking, allowing the machine safety system to verify both the position and locking condition of the guard before enabling the safety outputs.
The D working principle provides a power-to-unlock configuration, keeping a compatible actuator mechanically locked while the solenoid is de-energised. Separate O3 and O4 signalling outputs allow the control system to distinguish between actuator insertion and confirmed locking, while the base switch configuration provides flexibility to select the appropriate compatible actuator and wiring arrangement separately.
Typical Applications
- Machine guard doors and access panels.
- Robotic cells and automated manufacturing systems.
- Packaging and processing machinery.
- Automated production and assembly lines.
- Machining centres and industrial machine tools.
- Conveyor and material handling equipment.
- Guarded hazardous areas requiring controlled access.
- Industrial machinery requiring guard locking until safe conditions are reached.
