NG 2D5D419Z-F31 Pizzato NG series safety switch with lock and integrated control devices, with actuator

Why Choose the Pizzato NG 2D5D419Z-F31 Safety Switch?

The Pizzato NG 2D5D419Z-F31 is an advanced RFID safety switch with guard locking, three integrated control devices and a high-level coded actuator, designed for monitoring and securing movable guards on industrial machinery. Part of the Pizzato NG series, it combines electronically coded guard detection, high-force guard locking, electronic safety outputs and local operator controls within one robust assembly.

This exact configuration incorporates three integrated operator controls: a green 1NO push button in position 1, a blue 1NO push button in position 2 and a red illuminable emergency-stop push button with rotation release and 2NC contacts in position 3. The switch uses working principle D, meaning the actuator remains locked when the electromagnet is de-energised, providing a power-to-release guard-locking arrangement.

The NG 2D5D419Z-F31 is supplied complete with the VN NG-F31 high-level coded actuator and provides a holding force of 9750 N. Its powder-coated metal housing, orientable head with key-operated auxiliary release, three M20 × 1.5 threaded cable entries and IP65 protection for the integrated-control configuration make it suitable for demanding automated machinery and production equipment.

Key Advantages

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

Reliable Guard Monitoring for Industrial Machinery

Pizzato NG RFID safety locking switches are designed for machinery where movable guards must be electronically monitored and physically retained while hazardous functions remain active. High-level coded actuator recognition provides reliable guard detection with enhanced resistance to manipulation, while the power-to-release locking mechanism keeps the access point mechanically secured while the electromagnet is de-energised.

The NG 2D5D419Z-F31 combines this safety architecture with dedicated actuator and lock-status signals and three integrated operator controls. The green and blue push buttons can support local machine functions, while the red illuminable emergency-stop button provides an immediately accessible stopping control at the guarded access point. The key-operated auxiliary release further supports controlled intervention when manual unlocking is required.

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, local operator controls and an integrated emergency-stop function.
