Why Choose the Pizzato NG 2D1E421A-F31 Safety Switch with Lock?

The Pizzato NG 2D1E421A-F31 is an advanced RFID safety switch with guard locking and high-level coded actuator designed for monitoring and controlling access to hazardous areas of industrial machinery. As part of the Pizzato NG series, it combines electronic RFID actuator detection, guard locking and OSSD safety outputs in a robust device for demanding machine safety applications.

This version uses operating principle E, meaning that the actuator is locked when the solenoid is energised. It is configured for activation mode 2, in which the OS1 and OS2 safety outputs are active when the actuator is inserted, providing electronic guard-position monitoring for integration with compatible safety controllers.

The NG 2D1E421A-F31 is supplied with the VN NG-F31 uniquely coded RFID actuator, providing a high coding level according to EN ISO 14119. A metal housing, rotating head, three M20 × 1.5 threaded cable entries, maximum actuator holding force of 9750 N and IP67 / IP69K protection make it suitable for robust industrial guard-locking installations.

Key Advantages

  • Combines RFID guard monitoring and electromechanical guard locking in one industrial safety device.
  • Supplied with a VN NG-F31 high-level uniquely coded actuator.
  • Operating principle E locks the actuator when the solenoid is energised.
  • Mode 2 safety-output operation activates OS1 and OS2 when the actuator is inserted.
  • Maximum 9750 N actuator holding force for robust guard locking.
  • IP67 and IP69K protection for demanding industrial environments.

Key Features

  • Pizzato NG series RFID safety switch with lock.
  • VN NG-F31 high-level coded RFID actuator included.
  • 2 safety inputs IS1–IS2.
  • 2 OSSD safety outputs OS1–OS2.
  • O3 signalling output for actuator-inserted status.
  • O4 signalling output for actuator-locked status.
  • I3 input for actuator programming / reset.
  • Solenoid activation inputs for guard-lock control.
  • Rotating head for installation flexibility.
  • Metal housing with three M20 × 1.5 threaded cable entries.

RFID Guard Monitoring with Controlled Guard Locking

RFID safety switches use coded electronic actuator recognition to monitor whether a machine guard is correctly positioned. The uniquely coded VN NG-F31 actuator provides a high coding level, helping prevent the safety function from being easily defeated by an alternative actuator and making the system suitable for sophisticated industrial safeguarding applications.

The NG 2D1E421A-F31 adds electromechanical locking to RFID guard monitoring. With operating principle E, energising the solenoid locks the actuator, while dedicated signalling outputs provide information about actuator insertion and locking status. This combination allows compatible machine safety systems to monitor guard position while controlling access to hazardous machinery.

Typical Applications

  • Guard locking on automated production machinery.
  • Robotic cells and automated manufacturing systems.
  • Packaging and processing machinery.
  • Machine tools and hazardous production equipment.
  • Hinged and sliding industrial safety guards.
  • OEM machinery requiring high-level coded RFID interlocking.

Frequently Asked Questions

What is the Pizzato NG 2D1E421A-F31 used for?

The NG 2D1E421A-F31 is an RFID safety switch with guard locking used to monitor and control access through movable guards on industrial machinery.

Is an actuator included with the NG 2D1E421A-F31?

Yes. This -F31 version is supplied with the VN NG-F31 uniquely coded RFID actuator, which provides a high coding level according to EN ISO 14119.

How does the locking function of the NG 2D1E421A-F31 operate?

The switch uses operating principle E, meaning the actuator is locked when the electromagnetic solenoid is energised.

When are the safety outputs active on this model?

The NG 2D1E421A-F31 uses activation mode 2, so its OS1 and OS2 safety outputs are active when the actuator is inserted.

What safety outputs does the NG 2D1E421A-F31 provide?

The switch provides two OSSD safety outputs, OS1 and OS2, together with signalling outputs for actuator-inserted and actuator-locked status.

What is the maximum holding force of the Pizzato NG series lock?

The NG series provides a maximum actuator holding force of 9750 N, supporting robust guard-locking applications.

What ingress protection does the NG 2D1E421A-F31 provide?

The switch provides IP67 protection according to EN 60529 and IP69K protection according to ISO 20653, making it suitable for demanding industrial environments.
