Overview

2.1 x 5.5mm DC Coaxial Power In-line Panel Mount Feed-Thru Barrel Power Jack

Complete your low current DC project quickly, and with a professional finish, using this 2.1 x 5.5 mm inline DC jack. Many audio amplifier boards come with a DC coax jack, but need an internal jumper to reach the outer casing. This inline coupler easily hooks the internal DC jack with a male-to-male DC coax jumper without having to solder. The inline coupler's inside lining is all metal and accepts up to 11 mm long plugs without exposing the plugs barrel.

The inline coupler works perfect for portable speaker projects that use thick wood enclosures. The coupler requires a 0.36" (9 mm) hole inside the enclosure and a recessed 0.475" (12 mm) hole 0.50" deep from the outside if using 0.75" wood. It includes a 0.2" (5 mm) wide nut that tightens on to the 0.37" (9.5 mm) long x 0.36" (9 mm) diameter threaded shaft. Recess the hole more than 0.5" deep to keep the coupler from sticking out from the outside of the enclosure.

Specifications: Jack size: • 2.1 x 5.5 x 11 mm • Inline coupler total dimensions: 1.75" L x 0.475" Dia. (44.22 x 12 mm) at its widest point • Inner shaft with thread: 1.06" L x 0.36" Dia. with 0.37" L thread • Outer shaft with plastic nut dimensions: 0.69 L x 0.475" Dia.
