NG 2D5D421C-F31 Pizzato NG series safety switch with lock and integrated control devices, with actuator

Why Choose the Pizzato NG 2D5D421C-F31 Safety Switch with Lock?

The Pizzato NG 2D5D421C-F31 is a robust RFID safety switch with guard locking and integrated control devices designed for monitoring and securing movable machine guards in demanding industrial safety applications. As part of the advanced Pizzato NG series, it combines non-contact RFID actuator detection, electromagnetic guard locking and integrated operator controls within a heavy-duty metal housing.

This safety switch uses a digitally coded RFID actuator to provide reliable guard detection while helping prevent straightforward substitution of the actuator. The supplied VN NG-F31 high-coding-level actuator supports applications requiring enhanced tamper resistance in accordance with modern machine safety principles, while redundant electronic safety architecture enables integration into high-performance safety circuits.

The NG 2D5D421C-F31 features a 9750 N maximum actuator holding force, three M20 × 1.5 cable entries and integrated control devices including white and yellow pushbuttons plus a red emergency control device. Its metal construction and IP65 protection rating with integrated controls make it suitable for machinery, automated production systems and guarded industrial equipment.

Reliable Guard Monitoring and Locking for Industrial Machinery

RFID safety switches such as the Pizzato NG series monitor the presence of a machine guard using electronically coded, non-contact actuator detection. When combined with electromagnetic locking, the switch can prevent access to hazardous machine areas while dangerous movement or stored energy remains present.

The NG 2D5D421C-F31 further integrates operator control devices into the switch housing, reducing the number of separate components required around a guarded access point. Its safety inputs, redundant safety outputs and signalling outputs allow straightforward integration with safety PLCs, relays and machine control systems.

Typical Applications

• Guard doors on automated production machinery.
• Industrial robots and robotic manufacturing cells.
• Packaging and processing machinery.
• Conveyor and material handling systems.
• Machine tools and automated assembly equipment.
• Applications requiring high-coding-level RFID guard monitoring.
