What Are Barrel Connectors?

Barrel connectors (also known as DC barrel connectors, barrel jacks, or barrel plugs) are cylindrical connectors commonly used in low-voltage DC power applications. They're found in countless consumer electronics like routers, modems, LED lights, cameras, and audio equipment.

The male component is typically referred to as the barrel plug, and the female component is the barrel jack. These connectors come in various sizes and polarities, with common dimensions like 5.5mm x 2.1mm and 5.5mm x 2.5mm being among the most widely used.
