How it works and how to install it
The 2.1mm DC female jack is mounted by drilling a 12mm hole in the desired panel or enclosure, then inserting the jack body, applying the spring washer, and tightening the hex nut on the opposite side — the operation takes less than 5 minutes and requires no special tools. The flat terminals on the back of the jack are connected to the positive and negative wires of the installation by soldering with a soldering iron or by clamps, depending on the application. Once mounted, the jack accepts any DC 5.5/2.1mm male connector, ensuring continuous power to the circuit.
