Why Choose the Pizzato NG 2D5D511A Safety Switch?

The Pizzato NG 2D5D511A is a robust RFID safety switch with guard locking designed for secure monitoring and locking of movable guards, access doors and protective panels on industrial machinery. As part of the advanced Pizzato NG series, it combines non-contact RFID actuator detection, electronic safety outputs and high-strength mechanical guard locking in a durable metal housing.

Designed for demanding machine safety applications, the NG 2D5D511A uses a digitally coded RFID actuator system to provide reliable guard detection while supporting high safety performance. Its electronic architecture provides two safety inputs and two OSSD safety outputs, together with dedicated signalling outputs for actuator insertion and locking status, allowing straightforward integration with safety PLCs and machine control systems.

The NG 2D5D511A uses the D working principle, meaning the actuator is locked while the electromagnet is de-energised. With an actuator holding force of up to 9750 N, a rotating head with key-operated auxiliary release and a rugged metal housing with three M20 × 1.5 threaded cable entries, it provides dependable protection for industrial machinery where access must remain prevented until hazardous conditions have ended.

Key Advantages

  • Advanced RFID safety switch with mechanical guard locking.
  • High actuator holding force of up to 9750 N for demanding guard applications.
  • D working principle keeps the actuator locked with the electromagnet de-energised.
  • Electronic OSSD safety outputs support modern safety controllers and PLC systems.
  • Dedicated outputs provide clear actuator inserted and actuator locked status.
  • RFID technology enables reliable, non-contact guard position detection.
  • Robust metal housing designed for industrial environments.
  • Rotating head provides installation flexibility around machinery and guard structures.

Key Features

  • Pizzato NG series safety locking switch.
  • Non-contact guard detection using RFID technology.
  • Digitally coded actuator recognition.
  • 9750 N maximum actuator holding force.
  • 2 safety inputs IS1-IS2.
  • 2 electronic safety outputs OS1-OS2.
  • O3 signalling output for actuator inserted status.
  • O4 signalling output for actuator locked status.
  • I3 actuator programming/reset input.
  • I5 external device monitoring feedback input.
  • Electromagnet activation inputs for controlled guard release.
  • Safety outputs activated when the actuator is inserted and locked.
  • Rotating head with key-operated auxiliary release.
  • Metal housing with three M20 × 1.5 threaded cable entries.
  • Designed to support high-performance machine safety architectures.

Reliable Guard Locking for Industrial Machinery

Safety locking switches are used where opening a machine guard before hazardous movement has stopped could expose personnel to risk. The Pizzato NG series combines RFID-based guard detection with a high-strength mechanical locking system, enabling the safety controller to verify both that the guard is correctly positioned and that the actuator is securely locked before machinery operates.

The NG 2D5D511A provides electronic safety inputs and OSSD outputs for integration into modern industrial safety systems. Separate signalling outputs for actuator insertion and locking status improve machine diagnostics, while the auxiliary release and rotating head provide practical flexibility for installation, commissioning and maintenance.

Typical Applications

  • Industrial machine guard doors and access panels.
  • Robotic cells and automated production systems.
  • Packaging and processing machinery.
  • Conveyor and material handling equipment.
  • CNC machines and machine-tool guarding.
  • Automated assembly and manufacturing lines.
  • OEM machinery requiring RFID guard monitoring and locking.

Frequently Asked Questions

What is the Pizzato NG 2D5D511A used for?

The NG 2D5D511A is used to monitor and lock movable machine guards, access doors and protective panels, helping prevent access to hazardous machinery until safe conditions have been established.

How does the NG 2D5D511A locking system operate?

This model uses the D working principle, which keeps the actuator mechanically locked while the electromagnet is de-energised and allows controlled release through the machine safety system.

What is the holding force of the Pizzato NG 2D5D511A?

The NG series locking mechanism provides a maximum actuator holding force of up to 9750 N, making it suitable for demanding industrial guard-locking applications.

Does the NG 2D5D511A include an actuator?

No. The NG 2D5D511A is the safety switch version without an actuator; compatible NG actuators are available separately, including F30 low-level coded and F31 high-level coded versions.

What safety outputs does the NG 2D5D511A provide?

The switch provides two electronic safety outputs, OS1 and OS2, together with signalling outputs for actuator inserted and actuator locked status for integration with industrial safety control systems.
