Through-Panel-Mount Connectors

Before making a permanent connection, use these connectors to test a circuit. Also known as binding posts, they mount through panels to create a connection point.

All connectors are insulated to prevent contact with panels.

Gold-plated brass conducts the best. Tin-plated brass lasts the longest. Nickel-plated brass offers a good compromise between conductivity and longevity.

Single banana jacks come in your choice of color. Double banana jacks come with one red jack and one black jack, and your choice of color for the mounting base.

Hand-held voltage ratings are the maximum tested voltage for applications where you hold a cord connected to the jack in your hands while testing. Hands-free voltage ratings are the maximum voltage the jack is rated to withstand.

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. Solder connections are the most secure and permanent connection.

IP68-Rated Connectors—Create a sealed connection when the plug and socket, receptacle, or adapter are also IP68 rated. All are dust tight, even when there’s continuous airflow. They also withstand submersion 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.
