DC Power Jack

DC power jack male connector normally comes with 12-volt DC power supply adaptor. The power jack socket is female and consists of 3-pin. The bottom middle pin is the ground pin. The back pin is the live pin and the side pin is not used. This power jack socket is difficult to be mounted on the PCB because the pin size is quite big. Therefore a larger pin-hole size on the PCB is required.
