DC Barrel Plug to 2-Pin Terminal Block Adapter

This connector adapts a 5.5 × 2.1 mm DC barrel plug to a pair of screw terminals. The terminals are labeled positive and negative, with the positive terminal connected to the center contact.

This connector is compatible with our Barrel Jack Socket and fits the barrel jack socket on Arduino boards

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.
