NG 2D7D411F-F31 Pizzato NG series safety switch with lock and integrated control devices, with actuator

Why Choose the Pizzato NG 2D7D411F-F31 Safety Switch?

The Pizzato NG 2D7D411F-F31 is an advanced RFID safety switch with guard locking and integrated control devices, designed for monitoring and securing movable guards on industrial machinery. Part of the Pizzato NG series, this exact configuration combines high-strength guard locking with two integrated operator pushbuttons, providing guard monitoring, locking and local machine-control functions within a single robust assembly.

The integrated control station features a green 1NO+1NC pushbutton in position 1 and a red 1NO+1NC pushbutton in position 2. The switch is supplied complete with the VN NG-F31 high-level coded RFID actuator, providing individual actuator recognition and enhanced protection against manipulation in accordance with the high coding level principles of EN ISO 14119.

The NG 2D7D411F-F31 uses the D working method, with the actuator locked while the solenoid is de-energised, and provides a maximum actuator holding force of 9750 N. Its Mode 1 safety configuration activates OS1 and OS2 when the actuator is inserted and locked, while separate O3 and O4 signalling outputs communicate actuator-inserted and actuator-locked status to the machine control system.

Key Advantages

• Combines RFID guard monitoring, high-strength locking and integrated operator controls in one device.
• Integrated green 1NO+1NC and red 1NO+1NC pushbuttons provide convenient local machine-control functions.
• Supplied with a VN NG-F31 high-level coded RFID actuator for enhanced anti-tampering protection.
• Maximum actuator holding force of 9750 N supports demanding guard-locking applications.
• D working method keeps the actuator locked while the solenoid is de-energised.
• Mode 1 safety outputs provide confirmation that the actuator is inserted and locked.
• Dedicated O3 and O4 outputs provide separate actuator-inserted and actuator-locked status information.
• Rotating head with escape pushbutton supports release from inside a protected area.
• Integrated controls reduce the requirement for separate operator-control stations around the machine guard.

Integrated Guard Locking and Operator Control

The Pizzato NG 2D7D411F-F31 combines machine-guard interlocking with local operator controls, making it particularly useful where start, stop or other machine-control functions need to be positioned directly alongside a guarded access point. Its green and red pushbuttons each provide 1NO+1NC contacts, while the RFID safety system independently monitors the coded actuator and locking condition.

Mode 1 operation means the OS1 and OS2 safety outputs are active when the actuator is inserted and locked, allowing the safety system to verify the required guard condition before hazardous machine functions are enabled. The de-energise-to-lock D working method, 9750 N holding force and integrated escape pushbutton make the switch well suited to demanding automated machinery and guarded production areas.

Typical Applications

• Industrial machine guard doors and access gates.
• Robotic cells and automated manufacturing systems.
• Packaging and processing machinery.
• Automated assembly and production lines.
• Conveyor and material-handling systems.
• Machine tools with hazardous or high-inertia movement.
• Guarded areas requiring local green and red operator pushbuttons.
• Machinery requiring an internal escape-release function.
• OEM machinery and integrated industrial safety systems.
