NG 2D5D421A Pizzato NG series safety switch with lock

Why Choose the Pizzato NG 2D5D421A Safety Switch with Lock?

The Pizzato NG 2D5D421A is an NG series RFID safety switch with guard locking designed for monitoring movable guards and access doors on industrial machinery. It combines electronic actuator detection with a high-strength locking mechanism, providing machine builders with a robust solution for applications requiring reliable guard monitoring and controlled access.

This configuration uses Pizzato's D working method, with the actuator locked when the solenoid is de-energised. The switch incorporates a metal housing with three M20 × 1.5 threaded conduit entries and an orientable head with key-operated auxiliary release, while environmental protection reaches IP67 according to EN 60529 and IP69K according to ISO 20653.

The NG 2D5D421A operates in Mode 2, meaning the OS1 and OS2 safety outputs are active when a compatible actuator is inserted. Dedicated O3 and O4 signalling outputs separately indicate actuator insertion and locking status. This base version is supplied without an actuator, allowing the appropriate compatible Pizzato NG actuator to be selected separately.

Key Advantages

• Combines RFID actuator monitoring and high-strength guard locking.
• 9,750 N holding force provides robust retention of machine guards.
• De-energised-to-lock working principle supports controlled machinery access.
• Mode 2 safety-output operation with outputs active when the actuator is inserted.
• Two electronic safety inputs and two safety outputs for compatible safety-control systems.
• Separate signalling outputs indicate actuator insertion and confirmed locking.
• Key-operated auxiliary release supports controlled manual unlocking.
• IP67 / IP69K protection for demanding industrial environments.

Reliable RFID Guard Monitoring and Locking

The Pizzato NG platform combines electronic actuator detection with mechanical guard locking to provide dependable monitoring of protected machinery access points. With 9,750 N of holding force and separate electronic outputs for actuator insertion and locking status, the NG 2D5D421A enables compatible machine-control systems to monitor important guard conditions.

Mode 2 operation activates the OS1 and OS2 safety outputs when the compatible actuator is inserted, while the O4 signalling output independently indicates the locked condition. The base NG 2D5D421A is supplied without an actuator, providing flexibility to select the appropriate compatible NG actuator and coding arrangement for the installation.

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 electronic guard monitoring and high-strength locking.
