Why Choose the Pizzato NG 2D6D431A Safety Switch with Lock?
The Pizzato NG 2D6D431A is an advanced NG series RFID safety switch with guard locking designed for monitoring movable guards, doors and access gates on industrial machinery. This switch-only configuration combines electronic actuator detection, monitored locking and dual safety outputs in a robust metal housing, providing a dependable solution for safety-critical machine access points.
The NG 2D6D431A uses D working method, meaning the actuator is locked with the solenoid de-energised. Its rotating head incorporates a lock auxiliary release device and escape pushbutton, providing controlled unlocking for authorised intervention together with an escape-release function for personnel inside a guarded area.
A defining feature of the NG 2D6D431A is its Mode 3 safety-output configuration. OS1 becomes active when the actuator is inserted and locked, while OS2 becomes active when the actuator is inserted. This provides differentiated electronic information about guard and locking conditions for integration with compatible safety-control systems. The NG 2D6D431A is supplied without actuator and without connector, allowing the appropriate NG actuator and connection arrangement to be selected for the installation.
Key Advantages
- Combines RFID guard monitoring and robust guard locking in one industrial safety switch.
- Mode 3 safety logic provides differentiated monitoring of actuator insertion and confirmed locking.
- OS1 safety output becomes active with the actuator inserted and locked.
- OS2 safety output becomes active with the actuator inserted.
- D working method keeps the actuator locked when the solenoid is de-energised.
- 9,750 N maximum holding force supports demanding guard-locking applications.
- Dedicated O3 and O4 signalling outputs provide separate guard and lock status information.
- Rotating head with key-operated auxiliary release and escape pushbutton supports practical access requirements.

Reliable Mode 3 Guard Monitoring and Locking
The Pizzato NG 2D6D431A is particularly useful where the safety-control system needs differentiated information about guard position and confirmed locking. In Mode 3, OS1 is active when the actuator is inserted and locked, while OS2 is active when the actuator is inserted. Dedicated O3 and O4 signalling outputs additionally communicate actuator-inserted and actuator-locked conditions.
Its metal housing, 9,750 N maximum holding force, IP67/IP69K protection and rotating head make the NG 2D6D431A suitable for demanding machine environments. Because this model is supplied without an actuator, the appropriate compatible NG actuator can be selected separately according to the required coding level and installation requirements.
Typical Applications
- Industrial machine guard doors and safety gates.
- Robotic cells and automated manufacturing systems.
- Packaging and processing machinery.
- Automated assembly and production lines.
- Material handling and conveyor equipment.
- Machine tools and manufacturing centres.
- Guarded machinery requiring separate guard and lock status monitoring.
- Safety-critical access points requiring monitored guard locking.
