What is a panel interface connector?

A panel interface connector (PIC) is an enclosure-mounted connection point that provides outside access to equipment inside a control cabinet. Also called a programming port or programming interface, it lets technicians connect for programming and diagnostics without opening the main panel door.

⚠️ Safety: Keeping the main cabinet door closed can reduce exposure to energized components during connection tasks. A PIC prevents the risks caused by arc-flash hazards but does not replace required electrical safety procedures.

1. 🔎 Choose an Interface for the Job

Standard Panel Interface Connectors

Build a programming interface with room for multiple connections. Choose from six housing sizes with solid covers.
