NG 2D6D424X-F31 Pizzato NG series safety switch with lock and integrated control devices, with actuator

Why Choose the Pizzato NG 2D6D424X-F31 Safety Switch?

The Pizzato NG 2D6D424X-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, it combines electronically coded RFID actuator detection, robust mechanical guard locking and operator control functions within a single heavy-duty device.

The NG 2D6D424X-F31 uses a high-level coded VN NG-F31 RFID actuator, allowing the switch to recognise its individually programmed actuator and helping protect machinery against deliberate or accidental defeat of the guard-monitoring system. The NG platform provides redundant electronic safety architecture capable of achieving PL e and SIL 3 with appropriate system design, while its safety inputs and outputs support straightforward integration with safety PLCs and safety modules.

This model uses the D working method, keeping the actuator locked with a de-energised solenoid, and incorporates a rotating head with lock auxiliary release and escape pushbutton. Its heavy-duty interlocking system provides a maximum actuator holding force of 9750 N, while the integrated control-device housing provides a practical all-in-one solution for guarded machinery and automated production equipment.

Reliable Guard Control for Industrial Machinery

Safety locking switches such as the Pizzato NG 2D6D424X-F31 are designed for machinery where opening a guard before hazardous movement has stopped could expose personnel to risk. The switch combines RFID guard detection with mechanical locking, allowing the safety-control system to monitor the actuator while keeping the associated door or guard secured when required.

The NG series' electronic safety architecture provides dedicated safety inputs and outputs together with actuator and lock-status signalling. Compatible NG devices can be connected in series in correctly engineered systems, enabling machine builders to create sophisticated multi-guard installations while retaining safety performance up to PL e.

Typical Applications

• Industrial machine guard doors and access gates.
• Robotic cells and automated manufacturing systems.
• Packaging and processing machinery.
• Assembly and production lines.
• Conveyor and material-handling systems.
• Machinery with rotating components or residual mechanical movement.
• Guarded equipment requiring integrated operator controls.
• OEM machinery and industrial safety-control systems.
