Round Panel Mount 5.5mm/2.1mm DC Barrel Jack Extension Cable
39 units available with a short lead time.
A panel-mount DC barrel jack extension cable that lets you add a clean, professional power input to any enclosure — without cutting custom-shaped holes. The round flange means you only need a standard 1″ (25 mm) drilled hole. Unscrew the plastic nut, insert through the panel, and tighten. Done.
The cable is 30 cm (11.8″) long with a 5.5 mm / 2.1 mm barrel jack on each end. The panel-mount end features a solid body with a forgiving plastic lip that neatly hides the drill hole. Compatible with panels from a few millimetres up to 16 mm thick.
