NG 2D1D421F-F31 Pizzato NG series safety switch with lock and integrated control devices, with actuator

Why Choose the Pizzato NG 2D1D421F-F31 Safety Switch with Lock?

The Pizzato NG 2D1D421F-F31 is an advanced RFID safety switch with guard locking and integrated control devices designed for monitoring and securing protective guards, doors and access points on industrial machinery. Part of the Pizzato NG series, it combines electronically coded actuator detection, high-strength mechanical guard locking and local operator functionality within a robust industrial assembly.

This model uses the D working principle, meaning the actuator remains locked while the locking electromagnet is de-energised. Its electronic architecture provides two IS1–IS2 safety inputs, two OS1–OS2 safety outputs and dedicated O3 and O4 signalling outputs for actuator-inserted and actuator-locked status. The 421 configuration uses Mode 2, with OS1 and OS2 active when the actuator is inserted.

The NG 2D1D421F-F31 is supplied complete with the VN NG-F31 high-level coded RFID actuator, providing enhanced resistance to actuator substitution and manipulation. Integrated control devices allow operator functions to be positioned directly at the guarded access point, while the NG locking mechanism provides a maximum actuator holding force of 9,750 N for demanding machine safety applications.

Key Advantages

• Combines RFID guard monitoring, mechanical guard locking and integrated operator controls within one assembly.
• Supplied with a VN NG-F31 high-level coded RFID actuator for enhanced protection against actuator substitution.
• Mode 2 safety output operation activates OS1 and OS2 when the actuator is inserted.
• 9,750 N maximum actuator holding force provides secure retention of protective machine guards.
• De-energised locking principle keeps the actuator locked while the locking electromagnet is not energised.
• Two electronic safety inputs and two safety outputs support integration with modern safety controllers.
• Separate O3 and O4 signalling outputs provide guard-position and guard-locking status information.
• Integrated control devices help reduce the requirement for separate operator control stations.

Reliable Guard Monitoring and Operator Control for Industrial Machinery

The Pizzato NG 2D1D421F-F31 combines RFID guard detection with mechanical guard locking and electronic safety signals for integration into modern machine safety systems. Its Mode 2 configuration activates the OS1 and OS2 safety outputs when the actuator is inserted, while dedicated signalling allows the control system to monitor actuator insertion and locking status separately.

Integrated operator control devices allow machine functions to be positioned directly alongside the guard interlock, helping simplify control-station layouts and reduce separate machine components. Combined with the high-level coded F31 actuator and robust NG locking system, this makes the switch suitable for automated equipment requiring controlled access and reliable guard monitoring.

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 coded guard monitoring, secure locking and integrated operator controls.
