Why Choose the Pizzato NG 2D5D521A Safety Switch with Lock?
The Pizzato NG 2D5D521A is an NG series RFID safety switch with guard locking designed for monitoring and retaining movable guards on industrial machinery. It combines electronic actuator detection with a high-strength locking mechanism and electronic safety outputs, providing a robust solution for controlled access to hazardous machine areas.
This exact configuration uses Pizzato's D working principle, meaning the actuator is locked when the electromagnet is de-energised. The switch features a metal housing with three M20 × 1.5 threaded conduit entries and an orientable head with key-operated auxiliary release, while environmental protection is rated IP67 according to EN 60529 and IP69K according to ISO 20653.
The NG 2D5D521A provides two safety inputs, two safety outputs, separate signalling outputs for actuator insertion and locking, actuator programming/reset and an I5 EDM feedback input. It uses Mode 2 safety-output activation, with OS1 and OS2 active when a compatible actuator is inserted. This base configuration is supplied without an actuator.
Key Advantages
- Combines RFID actuator monitoring and high-strength guard locking.
- High 9,750 N holding force for robust machine-guard retention.

Reliable RFID Guard Monitoring with EDM Feedback
The Pizzato NG platform combines RFID actuator detection with mechanical guard locking to provide dependable monitoring of protected machinery access points. With a holding force of 9,750 N, the NG 2D5D521A is designed to retain compatible actuators securely while electronic outputs communicate guard and locking conditions to the machine safety system.
The I5 EDM feedback input enables external device monitoring to be incorporated into the safety architecture. Mode 2 operation activates OS1 and OS2 when the compatible actuator is inserted, while the separate O3 and O4 signalling outputs allow the control system to distinguish between actuator insertion and the mechanically locked condition.
Typical Applications
- Industrial machine guard doors and access gates.
- Robotic cells and automated manufacturing systems.
- Packaging and processing machinery.
- Automated assembly and production lines.
- Machine tools and manufacturing equipment.
- Material handling and conveyor systems.
- OEM machinery requiring RFID guard locking with EDM feedback monitoring.
