NG 2D1D621A-F31 Pizzato NG series safety switch with lock, with actuator

Why Choose the Pizzato NG 2D1D621A-F31 Safety Switch?

The Pizzato NG 2D1D621A-F31 is a robust RFID safety switch with guard locking designed for monitoring protected access points on industrial machinery and automated equipment. As part of the Pizzato NG series, it combines electronic actuator detection, monitored guard locking and electronic safety outputs within a durable metal housing for demanding machine safety applications.

The NG 2D1D621A-F31 uses working method D, meaning the actuator is locked when the electromagnet is de-energised. Its OS1 and OS2 safety outputs operate according to activation mode 2 and are active when the actuator is inserted. Separate signalling outputs provide actuator inserted status through O3 and fault status through O4, supporting integration with compatible machine safety controllers and automation systems.

Supplied complete with the VN NG-F31 high-coding-level RFID actuator, this configuration provides enhanced protection against inappropriate actuator substitution. The switch also offers a substantial 9750 N locking force, auxiliary release, a rotating head, metal housing and three threaded M20 × 1.5 conduit entries, making it suitable for heavy-duty industrial machine guarding applications.

High-Coding-Level Guard Protection for Industrial Machinery

Safety switches with guard locking are used on machinery where access through a guard or safety door must be monitored and controlled. The Pizzato NG 2D1D621A-F31 combines RFID-based actuator detection with a 9750 N locking mechanism, providing robust guard retention while allowing a compatible safety system to monitor the protected access point electronically.

The high-coding-level VN NG-F31 actuator provides increased protection against inappropriate actuator substitution, while activation mode 2 allows the OS1 and OS2 safety outputs to become active when the actuator is inserted. Dedicated O3 actuator-status and O4 fault outputs provide additional diagnostic information for machine control systems, helping support effective integration into modern industrial safety architectures.
