Figuring out Kobiconn DC Jack Datasheet

[electrosonic]

I am not sure what the highlighted measurement refers to. I think the the solder tabs are the same size (2.3mm on the other two diagrams)

Length and width of the connector.  The "2 x" on the lower one indicates the quantity because contacts 1 and 3I are the same size.

you can take a meter and measure, to be sure
but you have pin 1 which is tip,
pin 2 and 3 are connected unless the plug is inserted. it looks like pin 3 is the outer connection when the jack is in, so 2 would be where the battery connection goes.

if you are using a standard pedal configuration, ground goes to tip and positive to pin 3 and battery positive to pin 2. This disconnects the battery when the power plug is used.
Again check with a meter

Aha, that makes sense, but why is the terminal width 2.3mm in the other diagram (not 3.0mm)?

Maybe its their reccomendation on what size hole to make the PCB when mounting the component?

^Good point, it could be their foot print recommendation.  It could also be an error.

I am making the part for my eagle library, I guess I will have to wait until I actually have the part to verify the measurements.
