NG 2D7D411R-F31 Pizzato NG series safety switch with lock and integrated control devices, with actuator

Why Choose the Pizzato NG 2D7D411R-F31 Safety Switch?

The Pizzato NG 2D7D411R-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 three integrated operator controls, providing safety interlocking and convenient local machine-control functions within a single robust metal assembly.

The integrated control station features a white 1NO pushbutton in position 1, a blue 1NO pushbutton in position 2 and a red emergency pushbutton 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, providing individually coded electronic guard detection and enhanced protection against manipulation.

The NG 2D7D411R-F31 uses the D working principle, keeping the actuator locked while the electromagnet is de-energised. Its locking mechanism provides a maximum actuator holding force of 9750 N, while Mode 1 safety-output operation activates OS1 and OS2 when the actuator is inserted and locked. A rotating head with escape pushbutton provides an additional internal release function for guarded areas.

Key Advantages

• Combines RFID guard monitoring, high-strength guard locking and three integrated control devices in one assembly.
• Integrated white and blue operator pushbuttons provide convenient local machine-control functions.
• Includes a red emergency pushbutton with turn-to-release operation and 2NC contacts.
• 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 principle keeps the actuator locked while the electromagnet is de-energised.
• Mode 1 safety outputs confirm that the actuator is inserted and the guard locking mechanism is engaged.
• Separate O3 and O4 signalling outputs provide actuator-inserted and actuator-locked status.
• Rotating head with escape pushbutton supports release from inside the protected area.

Integrated Guard Locking and Operator Control

The Pizzato NG 2D7D411R-F31 combines machine-guard interlocking with local operator and emergency controls, making it particularly useful where machine-control functions need to be positioned directly alongside a guarded access point. The white and blue pushbuttons provide local control inputs, while the red turn-to-release emergency pushbutton provides two normally closed contacts for integration into the appropriate control architecture.

Mode 1 operation means the OS1 and OS2 safety outputs become active when the high-level coded actuator is inserted and locked, allowing the safety-control system to verify both guard position and locking status before hazardous machine functions are enabled. The 9750 N holding force, de-energise-to-lock D principle and integrated escape pushbutton make this configuration particularly suitable for demanding automated machinery and enclosed 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 access points requiring integrated operator and emergency controls.
• Machinery requiring an internal escape-release function.
• OEM machinery and integrated industrial safety systems.
