I'm not sure what to make of this part. If this is the only info you
have on this part, I wouldn't use it until I get one in hand. It
looks to me like this is intended for the body of the part to sit in
the plane of the board with pins along the edges. Notice the drawing
shows the edge of the PCB being cut back for the part. The three
pins have two outlines, an inner and an outer one (I've got no idea
what that means). The two rectangles at the top look like surface
mount tabs to me. That is a very strange way to mount a part,
especially in the center of the board. Is that what you see?
I think this drawing can only be properly interpreted if you have a
clear idea of what the part looks like.

That is the link. I'm not too worried about cost. I'm really
wondering how to create the footprint that has the cutout in it.

0.2 inches wide or more) they can be routed, but that often costs a
bit more. A small rectangular pin is typically accommodated by
notching the edge of the board, but if you want it in the middle,
that would be a long notch.

an alignment pin. I had this exact problem and I just used round
holes large enough to push the pins through. In fact, I fudged the
sizes a bit so I didn't have lots of different drills. My power
connector (may be similar to yours) used five rectangular
electrical pins and one alignment pin. The round holes seemed to
work just fine. CUI jack barrel 5.5x2.1 mm PJ-051AH
