This male barrel connector, or “plug”, has a 3.0mm inner diameter and 2.1mm outer diameter. It is housed in a Molded strain relief plastic handle, for protective flexibility. Although there are multiple methods of attaching the plug to the end of the wire, it’s also possible to get plugs that come pre-attached to a cable.
