Most sources refer to this style of connector as “male”, but since it has a female basket at its center, some will refer to it as “female”. Please look at the product photos carefully to make sure this is the connector you are looking for. This connector is compatible with our DC barrel jack to 2-pin terminal block adapter and our PCB-mountable barrel jack.
Note: The positive and negative markings on the terminal block side correspond to a center-positive barrel plug (the side labeled “+” connects to the center of the barrel plug and the side labeled “-” connects to the outside); you can flip the connections to make a center-negative plug.
