NG 2D7D611C Pizzato NG series safety switch with lock

Why Choose the Pizzato NG 2D7D611C Safety Switch with Lock?

The Pizzato NG 2D7D611C is an advanced NG series safety switch with guard locking and integrated control devices, designed for reliable monitoring and controlled access on industrial machinery. This configuration combines electronic safety monitoring, a high-force locking mechanism and three operator control devices within a robust metal housing, providing a compact solution for guarded machine access points.

The NG 2D7D611C uses the D working principle, meaning the actuator is locked while the electromagnet is de-energised. It provides 2 safe inputs IS1–IS2 and 2 safe outputs OS1–OS2, together with signalling outputs for actuator-inserted and fault status. The safety outputs operate when the actuator is correctly inserted and locked, supporting integration with compatible safety controllers and safety PLCs.

This model features a three-device control cover comprising a white 1NO + 1NC pushbutton, a yellow 1NO + 1NC pushbutton and a red emergency-stop pushbutton with rotational release and 2NC contacts. A rotating head with escape pushbutton, 9750 N locking force, metal housing and three threaded M20×1.5 cable entries make the NG 2D7D611C particularly suitable for demanding machine-safety installations. The base NG 2D7D611C is supplied without an actuator.

Key Advantages

• Combines guard locking, electronic safety monitoring and three operator control devices in one assembly.
• High 9750 N locking force for demanding industrial guard applications.
• D working principle keeps the actuator locked while the electromagnet is de-energised.

Reliable Guard Locking for Industrial Machinery

Guard-locking safety switches are used where access to hazardous machine areas must remain restricted until dangerous movement or processes have stopped. The Pizzato NG 2D7D611C combines electronic guard monitoring with a high-force locking mechanism, enabling a compatible machine-safety system to verify that the actuator is inserted and securely locked before its safety outputs become active.

The integrated white and yellow pushbuttons, emergency-stop control and escape pushbutton make this configuration particularly useful at guarded access points where both safety interlocking and operator functions are required. The base NG 2D7D611C is supplied without an actuator, allowing the appropriate compatible actuator to be selected separately for the installation.

Typical Applications

• Automated production machinery and manufacturing cells.
• Robotic cells and perimeter guarding systems.
• Packaging and processing machinery.
• Machine-tool access doors and protective enclosures.
• Conveyor and material-handling systems.
• Automated assembly and production lines.
• Guarded areas requiring an internal escape-release facility.
• Industrial machinery requiring integrated local controls and emergency-stop functionality.
