Use this handy barrel connector to make your own custom length extension wire for LED flexible strips. Just use the convenient press terminal connectors to join the wire to the Barrel Connector. There’s no soldering or marettes needed. The connector has a 5.5 mm outer diameter with a 2.1 mm pin.
You can use wires from 14 gauge to 22 gauge with these connectors. We generally recommend 18-20 gauge for LED strip installations, depending on the length of the run and the LED load.
This model is the male barrel connector; the female version is available separately.
