Why Choose the Pizzato NG 2D7E321A-F31 Safety Switch?
The Pizzato NG 2D7E321A-F31 is an advanced RFID safety switch with guard locking designed for secure monitoring and controlled access to movable guards, doors and protective barriers on industrial machinery. Part of the Pizzato NG series, it combines coded non-contact actuator detection, electronic safety monitoring and guard locking within a robust industrial safety device.
This model uses the E working method, with the actuator locked when the electromagnet is energised. Its electronic safety architecture provides two safety inputs and two safety outputs, together with dedicated signalling outputs for actuator insertion and actuator locking. This allows the switch to communicate essential guard status information to compatible safety controllers and machine automation systems.
The NG 2D7E321A-F31 is supplied with the VN NG-F31 high-coding-level RFID actuator. The F31 actuator provides a high coding level according to EN ISO 14119, helping protect the safety function against actuator substitution. The switch features a rotating head with an escape pushbutton and a metal housing with three M20 × 1.5 threaded cable entries for industrial installation.

Reliable Safety Control for Industrial Machinery
RFID safety locking switches such as the Pizzato NG series are designed for machinery where protective guards must be monitored and secured while hazardous machine conditions are present. RFID actuator recognition provides coded electronic guard detection without mechanical contact, while the locking mechanism prevents the associated guard from being opened when the safety system requires continued protection.
The NG 2D7E321A-F31 uses the E working method, meaning the actuator is locked when the electromagnet is energised. Its two safety inputs, two electronic safety outputs and dedicated actuator and lock-status signalling allow compatible safety controllers to coordinate guard access with machine operation. The high-coding-level F31 actuator provides additional protection against inappropriate actuator substitution.
