Why Choose the Pizzato NG 2D1D411A-F31 Safety Switch with Lock?
The Pizzato NG 2D1D411A-F31 is a robust RFID safety switch with solenoid guard locking and high-level coded actuator designed for monitoring and securing guards, doors and access points on industrial machinery. Part of the Pizzato NG series, it combines RFID actuator recognition with high-strength mechanical locking and electronic safety outputs for dependable machine guarding.
The NG 2D1D411A-F31 uses the D working method, meaning the actuator remains locked when the solenoid is de-energised. Its Mode 1 safety configuration activates both OS1 and OS2 safety outputs only when the 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 model is supplied complete with the VN NG-F31 high-level coded RFID actuator, which is individually coded for enhanced protection against foreseeable manipulation. The switch features a durable metal housing, rotating head, three M20 × 1.5 threaded conduit entries and an actuator holding force of 9750 N, with IP67 and IP69K protection for demanding industrial environments.

High-Level Coded RFID Guard Locking for Machine Safety
Guard-locking safety switches are used where opening a machine guard before hazardous movement has stopped could expose personnel to risk. The Pizzato NG 2D1D411A-F31 combines RFID actuator monitoring with mechanical guard locking, allowing the safety control system to verify that the guard is correctly closed and that the actuator is securely locked before the safety outputs become active.
The supplied VN NG-F31 high-level coded actuator is individually coded, so the associated switch recognises its programmed actuator rather than any interchangeable actuator of the same type. Combined with the de-energised-to-lock operating principle, high 9750 N holding force and separate inserted and locked status outputs, this provides a comprehensive solution for controlled access to hazardous machinery.
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 high-level coded actuators.
- Industrial machinery requiring locked access until safe conditions are reached.
