Well, I was not directly involved in choosing this part but at this point it is one of several being tried, of different technologies. This is not actually going to be used to sense a human finger but rather contact by cardboard boxes and other items in an automation system, and he doesn't really care too much about the ability to tell where (along the length) it was bumped, only whether contact was made or not. This part is nice because it is sealed, cheap, rugged, and very long (about 50cm) - the contact area he needs to sense is long and not a point.
