Description
DC Barrel connectors are one of the most popular connectors used for low power applications – there is no doubt, you likely have several of these laying around from long gone cordless phones and other devices. This DC Barrel Jack is the mating connector for all 2.1 x 5.5mm DC Barrel Plugs (Inner hole diameter x outer barrel diameter).
Unlike most DC Barrel Jacks, this one has narrower pins that with a 2.54mm pitch – making these compatible with standard Solderless Breadboards and Perfboards / Protoboards.
