Why Choose the Pizzato NG 2D1E311A-F31 Safety Switch with Lock?
The Pizzato NG 2D1E311A-F31 is an advanced RFID safety switch with guard locking and coded actuator designed for monitoring and controlling access to hazardous areas of industrial machinery. Part of the Pizzato NG series, this exact configuration features a robust metal housing, orientable head and high-strength locking mechanism, with no integrated control devices on the cover.
Unlike de-energised locking NG variants, the NG 2D1E311A-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 1 operation activates OS1 and OS2 when the actuator is both inserted and locked.
The switch is supplied complete with the VN NG-F31 high-level coded RFID actuator, which is individually associated with the switch for enhanced resistance to actuator substitution. With a maximum holding force of 9,750 N, IP67 and IP69K protection and three M20 × 1.5 cable entries, the NG 2D1E311A-F31 provides a durable guard-locking solution for demanding automated machinery.
Key Advantages
- Combines RFID coded guard monitoring and high-strength guard locking within one safety device.
- Supplied with a VN NG-F31 high-level coded RFID actuator for enhanced protection against actuator substitution.
- 9,750 N maximum holding force provides secure retention of protective machine guards.
- Energised locking principle locks the actuator when the electromagnet is energised.
- Mode 1 safety logic requires the actuator to be inserted and locked before OS1 and OS2 become active.
- Dedicated O3 and O4 signalling outputs provide separate actuator-inserted and actuator-locked status information.
- IP67 and IP69K protection supports use in demanding industrial environments.
- Metal housing and orientable head provide robust construction and flexible installation.

Reliable Guard Monitoring and Locking for Industrial Machinery
The Pizzato NG 2D1E311A-F31 combines non-contact RFID actuator detection with electronically controlled mechanical guard locking. Its Mode 1 configuration requires the coded actuator to be both inserted and locked before the OS1 and OS2 safety outputs become active, allowing the machine safety system to verify a secure guard condition before hazardous operation is permitted.
Dedicated O3 and O4 signalling outputs separately communicate actuator insertion and locking status, providing useful information for machine logic and diagnostics. The energised locking principle makes this configuration suitable for applications where guard locking is intentionally established by energising the electromagnet, while the robust metal housing and high environmental protection support demanding industrial installations.
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 coded guard monitoring and energised guard locking.
