NG 2D5D411A Pizzato NG series safety switch with lock

Why Choose the Pizzato NG 2D5D411A Safety Switch with Lock?

The Pizzato NG 2D5D411A is an advanced NG series RFID safety switch with guard locking designed for reliable monitoring and retention of movable guards on industrial machinery. Its electronic safety architecture combines non-contact actuator detection with a robust locking mechanism, making it suitable for machine builders and automation engineers requiring dependable access protection.

This configuration uses the Pizzato D working method, meaning the actuator is locked when the solenoid is de-energised. It incorporates two safety inputs, two electronic safety outputs and dedicated signalling outputs for actuator insertion and locking status. In activation mode 1, the OS1 and OS2 safety outputs become active when the actuator is both inserted and locked.

The NG 2D5D411A features a metal housing with three M20 × 1.5 threaded conduit entries, a rotating head with key-operated auxiliary release and protection to IP67 and IP69K. This base version is supplied without an actuator and without a connector, allowing the appropriate compatible NG actuator and connection arrangement to be selected separately for the application.

Key Advantages

• Advanced RFID guard monitoring with integrated locking for industrial machinery.
• 9,750 N maximum holding force for robust guard retention.

Reliable RFID Guard Locking for Industrial Machinery

The Pizzato NG series combines RFID-based actuator detection with mechanical guard locking to provide precise monitoring of protected machinery access points. For the NG 2D5D411A, the safety outputs are activated only when the associated actuator is detected in the inserted and locked condition, enabling the machine safety system to monitor the required guard state.

Its de-energised-to-lock operating principle keeps the actuator mechanically locked when the solenoid is not energised. Dedicated status outputs allow the control system to distinguish between actuator insertion and confirmed locking, while the auxiliary key release provides a controlled means of releasing the locking mechanism when required for authorised intervention.

Typical Applications

• Industrial machine guard doors and access gates.
• Robotic cells and automated manufacturing systems.
• Packaging and processing machinery.
• Machine tools and production equipment.
• Automated assembly and manufacturing lines.
• Material handling and conveyor installations.
• OEM machinery requiring monitored guard locking.
