Why Choose the Pizzato NG 2D1E321D-F31 Safety Switch with Lock?
The Pizzato NG 2D1E321D-F31 is an advanced RFID safety switch with guard locking and integrated control devices designed for monitoring and controlling access to hazardous areas of industrial machinery. Part of the Pizzato NG series, this configuration combines electronically coded actuator detection, energised guard locking and three integrated operator controls within a robust metal housing.
The NG 2D1E321D-F31 uses the E working principle, meaning the actuator is locked when the electromagnet is energised. Its electronic architecture provides two IS1–IS2 safety inputs, two OS1–OS2 safety outputs, an O3 signalling output for actuator-inserted status and an O4 signalling output for actuator-locked status. Mode 2 operation activates OS1 and OS2 when the actuator is inserted, while the separate O4 output communicates the locking condition.
Three integrated controls provide local machine operation directly at the guarded access point: a white 1NO+1NC pushbutton in position 1, a black 1NO+1NC pushbutton in position 2 and a red emergency stop button with turn-to-release operation and 2NC contacts in position 3. The switch is supplied complete with the VN NG-F31 high-level coded RFID actuator and provides a maximum holding force of 9,750 N.
Key Advantages
- Combines RFID guard monitoring, guard locking and three integrated operator controls within one assembly.
- White 1NO+1NC pushbutton provides a versatile local operator command.
- Black 1NO+1NC pushbutton provides a second independent operator command.
- Red 2NC emergency stop button with turn-to-release operation provides an integrated emergency control function.
- Supplied with a VN NG-F31 high-level coded RFID actuator for enhanced protection against actuator substitution.
- 9,750 N maximum holding force supports secure retention of protective machine guards.
- Energised locking principle locks the actuator when the electromagnet is energised.
- Mode 2 safety logic activates OS1 and OS2 when the actuator is inserted.

Reliable Guard Monitoring and Integrated Operator Control
The Pizzato NG 2D1E321D-F31 combines coded RFID guard detection with energised mechanical guard locking and redundant electronic safety outputs. Its Mode 2 configuration activates OS1 and OS2 when the coded actuator is inserted, while the dedicated O4 signalling output independently communicates the actuator-locking condition to the machine control system.
The integrated white and black control pushbuttons provide convenient local operator commands, while the red 2NC emergency stop button adds an emergency control directly at the guarded access point. This integrated arrangement can simplify machine layouts, reduce separate operator-control components and provide essential machine functions alongside the guard interlock.
Typical Applications
- Machine guard doors and protective access panels.
- Automated production and assembly machinery.
- Robotic cells and safeguarded manufacturing areas.
- Packaging and processing equipment.
- Conveyor and material handling systems.
- Machine tools and automated manufacturing equipment.
- Industrial machinery requiring RFID guard monitoring, energised guard locking and integrated operator controls.
