This connector adapts a 5.5 × 2.1 mm DC barrel jack to a pair of screw terminals. The terminals are labeled positive and negative, with the positive terminal connected to the center pin.
Most sources refer to this style of connector as “female”, but since it has a center pin, some will refer to it as “male”. Please look at the product photos carefully to make sure this is the connector you are looking for. This connector is compatible with our 5.5 x 2.1mm power plugs.
