5.5mm x 2.1mm DC Male Barrel Jack with Wire Cable

Pre-wired 5.5mm x 2.1mm DC male connector

This DC jack cable combines a male barrel plug with pre-attached wires for a suitable low-voltage DC connection. The plug is listed with a 5.5mm outer diameter and a 2.1mm inner diameter.

It can be considered for compatible device power leads, replacement connections and electronics projects when the socket dimensions and electrical requirements match. Applications such as LED lighting or CCTV equipment do not establish automatic compatibility with every device.

Check polarity and electrical ratings

Match the plug to the socket’s inner size, outer size and required engagement length. A 5.5mm plug with a 2.1mm centre opening should not be assumed interchangeable with a 2.5mm version.

Verify which lead connects to the centre and outer contact using suitable test equipment. Do not assume centre-positive polarity or rely on wire colour alone. The equipment’s required voltage and polarity must match the supply.

Current rating, wire gauge, cable length and voltage limits are not specified here. Confirm them before choosing a load. Use appropriate insulation, strain relief and protection for the installation, with power disconnected while making connections. This connector is not intended for direct AC mains wiring.

The cable does not change, regulate or create a supply voltage. Browse connectors and cables at EPRO for other options.
