DC Power Connector

DC Power connector is used to interface between circuits and DC power supply.

Officially it is known as DC Barrel Jack but commonly spelled as DC power connector.

It is a three terminal Connector.

There are various kinds of DC power connector but this very easy, simple and cheaper, thus used in wide variety of applications.

This connector easily fits into breadboard and PCB, so are widely used in applications to connect DC power from its adapter to the circuit.

This Power Jack can fit 2.1mm male connector. They are available in different sizes.
