NG 2D5D412F-F31 Pizzato NG series safety switch with lock and integrated control devices, with actuator

Why Choose the Pizzato NG 2D5D412F-F31 Safety Switch?

The Pizzato NG 2D5D412F-F31 is an advanced RFID safety switch with guard locking, three integrated control devices and high-level coded actuator, designed for reliable monitoring and locking of movable guards on industrial machinery. Part of the Pizzato NG series, it combines electronically coded guard detection, high-force locking, electronic safety outputs and local operator controls within one robust industrial assembly.

This configuration incorporates three integrated control devices: a red emergency-stop push button with rotation release and 2NC contacts, a white push button with 1NO contact, and a two-position key selector with 1NO contact. The switch uses working principle D, meaning the actuator remains locked when the electromagnet is de-energised, while the orientable head includes a key-operated auxiliary release.

The NG 2D5D412F-F31 is supplied complete with the VN NG-F31 high-level coded actuator and provides a holding force of 9750 N. Its metal housing, three M20 × 1.5 threaded cable entries, IP65 protection for the integrated-control configuration and comprehensive electronic safety interface make it suitable for demanding automated machinery and safety-critical production equipment.

Key Advantages

• Combines RFID guard monitoring, guard locking and three operator controls within one device.
• Supplied with VN NG-F31 high-level coded actuator for enhanced resistance to interlock manipulation.
• 9750 N holding force supports secure retention of industrial machine guards.
• Power-to-release working principle D keeps the actuator locked when the electromagnet is de-energised.
• Integrated emergency stop, push button and key selector consolidate important operator functions at the guarded access point.
• Key-operated auxiliary release provides controlled manual release of the locking mechanism.

Reliable Guard Monitoring for Industrial Machinery

RFID safety locking switches such as the Pizzato NG series are designed for machinery where movable guards must be electronically monitored and physically retained while hazardous functions remain active. High-level coded actuator recognition helps resist manipulation of the safety interlock, while the power-to-release locking mechanism keeps the access point mechanically secured while the electromagnet is de-energised.

The NG 2D5D412F-F31 combines this safety architecture with three useful operator controls directly on the switch assembly. The emergency-stop button, white push button and key-operated selector reduce the need for separate control stations around the guarded access point, while dedicated safety and signalling outputs provide comprehensive integration with the machine safety system.

Typical Applications

• Industrial machine guard doors and access panels.
• Robotic cells and automated production equipment.
• Packaging and processing machinery.
• Automated manufacturing and assembly lines.
• CNC machines and industrial machine tools.
• Conveyor and material handling systems.
• Machinery requiring guard locking, emergency stopping and local operator controls at a single access point.
