Descrizione

This is a standard PCB-mountable barrel jack for DC power adapters with 2.1 mm center holes. This jack is compatible with our wall-adapter power supplies:

5VDC 1A adapter
5VDC 3A adapter
9VDC 1A adapter
9VDC 3A adapter
12VDC 1A adapter
12VDC 3A adapter
12VDC 5A adapter

Dimensions (in mm) for the DC power adapter barrel jack.

The jack has three pins: pin 1 comes out of the back of the jack and is connected to the center pole, pin 2 comes out of the bottom of the jack and is connected to the side wall, and pin 3 comes out the side of the jack and is automatically switched based on whether there is anything plugged into the jack. With nothing plugged into the jack, pins 2 and 3 are shorted together; with an adapter plugged into the jack, pin 3 is disconnected. This feature makes it easy to create a system that is powered by a wall adapter when one is plugged into the jack and by a battery the remainder of the time.

For a DC jack that connects directly to a terminal block for easy connection of wires, see our DC barrel jack to 2-pin terminal block adapter.
