Schematic Needed
Is there a schematic for these pins? It would be nice to know the detailed specifications.

It's a standard size with standard characteristics (diameters, length, pin travel, etc.). Just Google "P100-E2".

They're (mostly) temporary contacts for automated electronics tests. You populate a circuit board, then send it to a test station where a set of pins like these come down, contact several test points on the board, and run a number of tests to see if everything's working. Since there is no reason to plug anything into anything else, it saves a lot of time and eliminates a lot of potential damage.

That said, there are a lot of other potential uses for them as well that doesn't involve volume production of electronics, and because the pins are consumables (that is, they're not the sort of thing you'd salvage when the production job changes, and they need periodic replacement in huge production runs), they're pretty cheap, so they make good sensor probes for hobby projects (think 3D-printed stuff with motors and an Arduino or Raspberry Pi). They're poke-y sticks with a bit of give that you can put electricity through, and you'd be amazed at how often something like that can come in handy.
