Why Choose the Pizzato NG 2D1E421A-F31 Safety Switch with Lock?
The Pizzato NG 2D1E421A-F31 is an advanced RFID safety switch with guard locking and high-level coded actuator designed for monitoring and controlling access to hazardous areas of industrial machinery. As part of the Pizzato NG series, it combines electronic RFID actuator detection, guard locking and OSSD safety outputs in a robust device for demanding machine safety applications.
This version uses operating principle E, meaning that the actuator is locked when the solenoid is energised. It is configured for activation mode 2, in which the OS1 and OS2 safety outputs are active when the actuator is inserted, providing electronic guard-position monitoring for integration with compatible safety controllers.
The NG 2D1E421A-F31 is supplied with the VN NG-F31 uniquely coded RFID actuator, providing a high coding level according to EN ISO 14119. A metal housing, rotating head, three M20 × 1.5 threaded cable entries, maximum actuator holding force of 9750 N and IP67 / IP69K protection make it suitable for robust industrial guard-locking installations.

RFID Guard Monitoring with Controlled Guard Locking
RFID safety switches use coded electronic actuator recognition to monitor whether a machine guard is correctly positioned. The uniquely coded VN NG-F31 actuator provides a high coding level, helping prevent the safety function from being easily defeated by an alternative actuator and making the system suitable for sophisticated industrial safeguarding applications.
The NG 2D1E421A-F31 adds electromechanical locking to RFID guard monitoring. With operating principle E, energising the solenoid locks the actuator, while dedicated signalling outputs provide information about actuator insertion and locking status. This combination allows compatible machine safety systems to monitor guard position while controlling access to hazardous machinery.
Typical Applications
- Guard locking on automated production machinery.
- Robotic cells and automated manufacturing systems.
- Packaging and processing machinery.
- Machine tools and hazardous production equipment.
- Hinged and sliding industrial safety guards.
- OEM machinery requiring high-level coded RFID interlocking.
