DC Female Power Jack details PCB & Panel Mounting



DC female power jack are commonly used in electronic industry to connect adapters to your circuit board. Most commonly used DC female jack is 2.1mm x 5.5 mm DC jack. Where 5.5mm is the outer diameter and 2.1mm is the intrenal pin size. 

The DC plug (male) should match this dimension for proper matching. Most of the non proprietary co-axial power plugs match the 2.1 x 5.5 dimensions. In most of the DC plug the outer body is the negative supply and the internal is the positive.
