Why Choose the Pizzato NG 2D5D311D-F31 Safety Switch with Lock?

The Pizzato NG 2D5D311D-F31 is an advanced NG series safety switch with guard locking and integrated control devices, supplied complete with a high-coded actuator. Designed for industrial machine guarding, it combines electronic safety monitoring, robust guard locking and local operator controls within a durable metal housing.

This model uses the D working principle, with the actuator locked when the electromagnet is de-energised. It provides two safety inputs and two safety outputs, together with dedicated signalling outputs for actuator-inserted and actuator-locked status. Its orientable head also incorporates an auxiliary key release for applications requiring a means of manually releasing the locking mechanism.

The NG 2D5D311D-F31 incorporates a white pushbutton with 1NO + 1NC contacts, a black pushbutton with 1NO + 1NC contacts and a red emergency-stop pushbutton with turn-to-release action and 2NC contacts. It is supplied complete with the VN NG-F31 high-coding-level actuator and provides a maximum holding force of 9750 N.

Key Advantages

  • Combines guard monitoring, guard locking and three integrated control devices in one unit.
  • Supplied complete with the VN NG-F31 high-coding-level actuator.
  • 9750 N maximum holding force provides robust guard retention.
  • D working principle keeps the actuator locked while the locking electromagnet is de-energised.
  • Integrated white and black pushbuttons provide convenient local machine controls.
  • Integrated red turn-to-release emergency-stop pushbutton with 2NC contacts.
  • Auxiliary key release provides a means of manually releasing the guard-locking mechanism.
  • Separate O3 and O4 signalling outputs provide actuator-position and locking-status information.
  • Robust metal housing and orientable head support demanding industrial installations.

Key Features

  • Pizzato NG series RFID safety switch with guard locking.
  • VN NG-F31 high-coding-level actuator included.
  • D working principle – actuator locked with electromagnet de-energised.
  • 9750 N maximum holding force.
  • Position 1: white pushbutton, 1NO + 1NC.
  • Position 2: black pushbutton, 1NO + 1NC.
  • Position 3: red emergency-stop pushbutton, turn to release, 2NC.
  • 2 safety inputs: IS1 and IS2.
  • 2 safety outputs: OS1 and OS2.
  • Mode 1 safety-output activation: outputs active with actuator inserted and locked.
  • O3 signalling output indicates actuator inserted.
  • O4 signalling output indicates actuator locked.
  • I4 or IE1-IE2 inputs provide electromagnet activation control.
  • I3 provides the actuator programming / reset input.
  • Orientable head with auxiliary key release.
  • Metal housing with three M20 × 1.5 threaded cable entries.
  • IP65 protection according to EN 60529 for this integrated-control configuration.

De-Energised Guard Locking with Auxiliary Release

The Pizzato NG 2D5D311D-F31 uses the D working principle, in which the actuator remains locked while the locking electromagnet is de-energised. Its Mode 1 safety logic activates the OS1 and OS2 safety outputs only when the actuator is both inserted and locked, allowing the safety-control system to supervise the guard and locking condition.

An auxiliary key release is incorporated into the orientable head to provide a manual means of releasing the locking mechanism when required by the machine design. Combined with the high-coded VN NG-F31 actuator, integrated pushbuttons and emergency-stop control, this configuration provides a comprehensive guard-access solution for automated industrial machinery.

Typical Applications

  • Industrial machine guard doors and access panels.
  • Robotic cells and automated manufacturing systems.
  • Packaging and processing machinery.
  • Automated assembly and production lines.
  • Conveyor and material handling systems.
  • Machine tools and manufacturing equipment.
  • Guarding systems requiring de-energised electromagnetic locking.
  • Machinery requiring an auxiliary key-release facility.
  • Applications requiring integrated operator and emergency-stop controls.

Frequently Asked Questions

What is the Pizzato NG 2D5D311D-F31 used for?

The NG 2D5D311D-F31 is designed to monitor and lock guards and access points on industrial machinery while providing integrated operator controls and emergency-stop functionality.

Is an actuator included with the NG 2D5D311D-F31?

Yes. The switch is supplied complete with the VN NG-F31 high-coding-level actuator.

How does the locking principle of the NG 2D5D311D-F31 operate?

It uses the D working principle, meaning the actuator is locked while the locking electromagnet is de-energised.

What controls are integrated into the NG 2D5D311D-F31?

It incorporates a white 1NO + 1NC pushbutton, a black 1NO + 1NC pushbutton and a red turn-to-release emergency-stop pushbutton with 2NC contacts.

When are the safety outputs active?

The NG 2D5D311D-F31 uses Mode 1 safety-output activation, so its OS1 and OS2 outputs are active when the actuator is inserted and locked.

Does the NG 2D5D311D-F31 have an auxiliary release?

Yes. Its orientable head incorporates an auxiliary key release that provides a means of manually releasing the locking mechanism when required by the machine design.

What is the maximum holding force of the NG 2D5D311D-F31?
