Why Choose the Pizzato NG 2D5D311A-F31 Safety Switch?

The Pizzato NG 2D5D311A-F31 is a robust RFID safety switch with guard locking, key-operated auxiliary release and high-level coded actuator, designed for reliable monitoring and locking of movable guards on industrial machinery. As part of the Pizzato NG series, it combines electronically coded guard detection, high-force locking, electronic safety outputs and clear status signalling within a durable metal housing.

This configuration uses working principle D, meaning the actuator remains locked when the locking electromagnet is de-energised. This power-to-release operating principle is particularly suitable for machinery where the guard should remain mechanically locked if power to the locking circuit is removed. A key-operated auxiliary release provides controlled manual unlocking when required for servicing or machine access.

The NG 2D5D311A-F31 is supplied complete with the VN NG-F31 high-level coded actuator. It operates from a 24 V DC supply and provides an actuator holding force of 9750 N, while its IP67 / IP69K protection, orientable head and robust construction make it suitable for demanding industrial machine-guarding applications.

Key Advantages

  • Combines RFID guard monitoring and high-force guard locking within one robust safety device.
  • Supplied with VN NG-F31 high-level coded actuator for enhanced resistance to manipulation.
  • 9750 N actuator 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.
  • Key-operated auxiliary release provides controlled manual release of the locking mechanism.
  • IP67 and IP69K protection supports installation in demanding industrial environments.

Key Features

  • Pizzato NG series RFID safety locking switch.
  • VN NG-F31 high-level coded actuator included.
  • Working principle D, actuator locked with de-energised electromagnet.
  • 24 V DC supply voltage.
  • 9750 N actuator holding force.
  • Two safe inputs IS1 and IS2.
  • Two safe electronic outputs OS1 and OS2.
  • O3 signalling output for actuator-inserted status.
  • O4 signalling output for actuator-locked status.
  • Electromagnet-control inputs for integration with the machine safety system.
  • I3 reset / programming input.
  • Mode 1 safety-output operation with outputs active when the actuator is inserted and locked.
  • Key-operated auxiliary release.
  • Integrated LED status indication and orientable head.

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 reliably monitored and physically retained while hazardous functions remain active. The electronically coded actuator allows the switch to verify the guard condition while providing increased resistance to deliberate manipulation compared with conventional low-coding interlock arrangements.

The NG 2D5D311A-F31 combines high-level coded detection with power-to-release guard locking. Its dual safe inputs and electronic safety outputs, separate actuator and lock-status signals, high holding force and key-operated auxiliary release provide machine builders with a comprehensive solution for safety-critical access points on automated industrial equipment.

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 high-level coded, power-to-release guard locking.
