Barrel-Style DC Connectors

Made with industry standard barrel-style ends, these connectors carry DC power between electronic devices and power supplies.

Housing Connection—Pair connectors that have the same type of housing connection. Push-in connectors are quick to connect and disconnect. Screw-together connectors take longer to connect, but are more secure. They’re good for preventing power loss if vibration might loosen the connection or the connector could get yanked out.

Wire Connection—Choose based on your application. Wire leads come ready to connect and don’t require any preparation. Screw-clamp terminals are easy to use; just insert the wire into the terminal and tighten the screw to clamp it in place. Solder connections are the most secure and permanent connection.

IP-Rated Connectors—Create a sealed connection when the plug and socket, receptacle, or adapter are also IP rated. All are dust tight, even when there’s continuous airflow. IP64-rated connectors protect against water splashed from all directions. IP68-rated connectors have been tested by the manufacturer to withstand immersion in water for more than 30 minutes.

Receptacles—Mount them in a panel. Receptacles with an off (Normally Open) circuit position turn equipment on when you plug in a device. Receptacles with an on (Normally Closed) circuit position have an internal switch, or shunt, to transfer power from one component to another when you plug in a device. They’re often used with equipment that can run on either battery or wall power, switching off the battery connection when you plug into the wall. You can also use them to turn on a light inside the device when you plug it in.

Adapters—Use socket × socket adapters to join two cords for a longer length and to change the gender of your connection. Plug × socket adapters let you convert to the right barrel size for your connection.
