NG 2D6D521A-F31 Pizzato NG series safety switch with lock, with actuator

Why Choose the Pizzato NG 2D6D521A-F31 Safety Switch?

The Pizzato NG 2D6D521A-F31 is a heavy-duty RFID safety switch with guard locking, designed for monitoring and securing movable guards on industrial machinery and automated equipment. Part of the advanced Pizzato NG series, it combines high-level coded RFID actuator detection, robust mechanical guard locking and electronic safety outputs within a durable metal housing.

This configuration is supplied complete with a VN NG-F31 high-level coded RFID actuator, providing enhanced protection against manipulation of the guard-monitoring system. The switch incorporates two safe inputs and two semiconductor safety outputs, together with dedicated signalling outputs for actuator-inserted and actuator-locked status. An EDM feedback input also supports monitoring of external devices within appropriately designed machinery safety systems.

The NG 2D6D521A-F31 uses the D working principle, meaning the actuator remains locked while the electromagnet is de-energised. Its heavy-duty locking mechanism provides a maximum actuator holding force of 9750 N, while the orientable head incorporates an auxiliary key release and escape pushbutton. With no integrated control devices on the cover, this model provides a dedicated high-performance guard-locking solution for demanding industrial safety applications.

Reliable Guard Control for Industrial Machinery

Safety locking switches such as the Pizzato NG 2D6D521A-F31 are designed for machinery where a movable guard must remain secured while hazardous movement or other dangerous operating conditions are present. RFID actuator detection electronically monitors the position of the guard, while the mechanical locking system prevents withdrawal of the actuator until access can safely be permitted.

The NG series combines semiconductor safety outputs with detailed status signalling and feedback functionality for integration into modern machinery safety architectures. The high-level coded VN NG-F31 actuator provides additional protection against guard-system manipulation, while the auxiliary key release and escape pushbutton provide flexible access and emergency-release functionality.

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 and guarded manufacturing equipment.
• Machinery with residual hazardous movement requiring guard locking.
• OEM machinery and integrated industrial safety systems.
