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 Pololu's DC barrel plug to 2-pin terminal block adapter and Pololu's wall power adapters that are terminated with 5.5 × 2.1 mm barrel plugs.
Note: The positive and negative markings on the terminal block side correspond to a center-positive barrel jack (the side labeled “+” connects to the center pin of the barrel jack and the side labeled “-” connects to the outer portion); you can flip the connections to make a center-negative jack.
