- <blockquote>Is there a scientific way to estimate the resistance of a pogo pin?</blockquote>
- Ultimately there must be, but it generally requires knowing things you don't know.
- Worrying about the resistance of the barrel and spring is missing the point. The limiting factor will be the small contact area between the circuit board and the pogo pin point.
In any case, this is something you look up in the datasheet. The pogo pin manufacturer should be able to tell you what the minimum guaranteed resistance is between the pin and whatever it is touching, for different points and surfaces.
