NG 2D5D511A Pizzato NG series safety switch with lock

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.

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.
