NG 2D5D411H-F31 Pizzato NG series safety switch with lock and integrated control devices, with actuator

Why Choose the Pizzato NG 2D5D411H-F31 Safety Switch with Lock?

The Pizzato NG 2D5D411H-F31 is an advanced NG series RFID safety switch with guard locking and an integrated control device, supplied complete with a high-coded actuator. Designed for industrial machine guarding, it combines non-contact RFID actuator detection, electromagnetic guard locking and local operator control within a robust metal housing.

This configuration uses the D working principle, meaning the actuator is locked while the locking electromagnet is de-energised. Its Mode 1 safety logic activates the OS1 and OS2 safety outputs when the actuator is inserted and locked, while separate O3 and O4 signalling outputs provide actuator-inserted and actuator-locked status information.

The NG 2D5D411H-F31 incorporates a single white pushbutton with 1NO + 1NC contacts and features an orientable head with auxiliary key release. Supplied complete with the VN NG-F31 high-coding-level actuator, it provides a maximum holding force of 9750 N for demanding guarded machinery and automated production equipment.

Key Advantages

• Combines RFID guard monitoring, electromagnetic locking and local operator control in one device.
• Supplied complete with the VN NG-F31 high-coding-level actuator.
• 9750 N maximum holding force provides robust guard retention.
• D working principle retains the actuator while the locking electromagnet is de-energised.
• Mode 1 safety logic requires the actuator to be inserted and locked for safety-output activation.
• Integrated white 1NO + 1NC pushbutton provides convenient local operator control.
• Auxiliary key release provides a means of manually releasing the locking mechanism when required by the machine design.

RFID Guard Monitoring with De-Energised Locking

The Pizzato NG 2D5D411H-F31 combines RFID actuator detection with electromagnetic guard locking so that a machine-safety system can monitor a movable guard while controlling access to hazardous areas. Its D working principle retains the actuator while the locking electromagnet is de-energised, and its Mode 1 configuration enables the safety outputs when the actuator is both inserted and locked.

An auxiliary key-release mechanism is incorporated into the orientable head to provide manual release of the locking mechanism when required by the machine design. Together with the VN NG-F31 high-coded actuator, integrated white pushbutton and independent actuator-status outputs, this configuration provides a comprehensive guard-access solution for automated industrial machinery.

Typical Applications

• Industrial machine guard doors and access panels.
• Robotic cells and automated manufacturing systems.
• Packaging and processing machinery.
• Automated assembly and production lines.
• Conveyor and material-handling systems.
• Machine tools and production equipment.
• Guarding systems requiring de-energised electromagnetic locking.
• Applications requiring high-coded RFID actuator monitoring.
• Machinery requiring auxiliary key-release functionality.
• Guarded access points requiring an integrated local pushbutton.
