NG 2D6D411A Pizzato NG series safety switch with lock

Why Choose the Pizzato NG 2D6D411A Safety Switch?

The Pizzato NG 2D6D411A is an advanced RFID safety switch with guard locking designed for secure monitoring and locking of movable guards, access doors and protective panels on industrial machinery. Part of the Pizzato NG series, it combines non-contact RFID actuator recognition, electronic safety outputs and high-strength mechanical guard locking within a robust metal housing.

This model uses the D working method, meaning the actuator remains locked while the solenoid is de-energised. Its rotating head incorporates a key-operated auxiliary release device and escape pushbutton, providing both controlled release and an emergency means of unlocking the guard from within a protected area. The switch provides two safety inputs, two OSSD safety outputs and dedicated signalling outputs for actuator insertion and locking status.

The NG 2D6D411A is supplied without an actuator, allowing the appropriate compatible NG series RFID actuator to be selected separately for the required coding level. With a maximum actuator holding force of 9750 N, a metal housing with three M20 × 1.5 threaded conduit entries and IP67 / IP69K protection, it provides a robust safety solution for demanding industrial machinery.

Reliable Guard Locking for Industrial Machinery

Safety switches with guard locking are used where access to hazardous machine areas must remain prevented until dangerous movement or processes have stopped. The Pizzato NG series combines RFID-based actuator recognition with mechanical locking, enabling the machine safety system to verify that a guard is correctly positioned and securely locked before hazardous operation is permitted.

The NG 2D6D411A also provides practical release functionality through its key-operated auxiliary release and escape pushbutton. Its dual electronic safety outputs and dedicated diagnostic signals support integration with modern safety PLCs and controllers, while the separately selected actuator allows machine builders to choose the coding arrangement appropriate to the application.

Typical Applications

• Industrial machine guard doors and access points.
• Robotic cells and automated production systems.
• Guarded areas requiring an emergency escape facility.
• Packaging and processing machinery.
• Conveyor and material handling systems.
• CNC machines and machine-tool guarding.
• Automated assembly and manufacturing lines.
• OEM machinery requiring RFID guard monitoring and high-strength locking.
