5.5mm x 2.1mm DC Power Jack

This pack contains five female panel-mount DC power jack connectors with a 5.5mm outer diameter and 2.1mm inner pin size. They accept standard 2.1mm x 5.5mm male barrel plugs for DC power input. Each jack includes a fixing nut for secure panel installation. The components are suited for repairing or building power connections in consumer electronics.

Check Mounting Hole and Voltage Rating

Verify that your enclosure provides an 11.6mm diameter mounting hole with M12 threading for the panel nut. Confirm the circuit operates within the 30V DC rated load limit. Ensure the existing wiring uses a compatible 2.1mm centre-positive male barrel connector. The operating temperature range spans -30 to 70 degrees Celsius.

Contact Resistance and Insulation Performance

Contact resistance is specified at 0.03 ohms for low-loss power transfer. Insulation resistance reaches 100 megohms at the rated test voltage. The jack withstands 500V AC at 50Hz for one minute during dielectric testing. These parameters support reliable operation in audio, video, communication and household appliance applications.

Questions about this item

What comes in the pack and is any tool or extra part needed to install the jack?

The pack contains five DC power jacks and five panel-mount screw nuts; no additional parts are required for mounting.

Which jack should I pick if my device uses a 2.1 mm centre pin and 5.5 mm barrel plug?

This jack is built for a 2.1 mm centre pin and 5.5 mm barrel, so it matches that exact plug size.

What does the 30 V rating mean when the jack is fitted in my equipment?

The jack is rated for up to 30 V DC, so it will safely carry any supply at or below that voltage.
