NG 2D5D521A-F31 Pizzato NG series safety switch with lock, with actuator

Why Choose the Pizzato NG 2D5D521A-F31 Safety Switch with Lock?

The Pizzato NG 2D5D521A-F31 is an NG series RFID safety switch with guard locking and high-coded actuator designed for monitoring protected access points on industrial machinery. It combines electronic actuator detection with a high-strength mechanical locking system, providing reliable guard monitoring and controlled access for automated equipment and machine safety applications.

This configuration uses Pizzato's D working principle, meaning the actuator is locked when the electromagnet is de-energised. The robust metal housing incorporates three M20 × 1.5 threaded conduit entries, while the orientable head includes a key-operated auxiliary release. The switch provides IP67 protection according to EN 60529 and IP69K according to ISO 20653.

The NG 2D5D521A-F31 is supplied with a high-coding-level F31 actuator and includes an I5 EDM feedback input for monitoring external devices. Its Mode 2 configuration activates the OS1 and OS2 safety outputs when the actuator is inserted, while separate O3 and O4 signalling outputs indicate actuator insertion and locking status.

Key Advantages

• Combines RFID actuator detection and high-strength guard locking.
• Supplied with a high-coding-level F31 actuator.
• High 9,750 N maximum holding force for robust guard retention.

Reliable RFID Guard Monitoring with EDM Feedback

The Pizzato NG platform combines RFID actuator detection with mechanical guard locking to provide dependable monitoring of protected machinery access points. On the NG 2D5D521A-F31, Mode 2 operation means the OS1 and OS2 electronic safety outputs are active when the high-coded actuator is inserted, allowing compatible safety-control equipment to monitor the guard condition.

The additional I5 EDM feedback input supports monitoring of external switching devices within the machinery safety architecture. Combined with the 9,750 N maximum holding force, high-coded actuator, auxiliary release and dedicated actuator and lock-status outputs, the NG 2D5D521A-F31 provides a comprehensive solution for sophisticated automated machinery.
