Thanks Peter. What would be a good maximum frequency to work with? You will know a lot more than I do

I would say a couple hundred KHz so pretty much any encoder interface could work.
Also better if its a square wave so it asks the least of the frequency/period counter.
An offset frequency is good also so you don't lose bandwidth near 0 frequency.

Thanks Peter for your opinion.
You strongly confirmed my analyses.
I suggest 20-70kHz (0-10mm) and 10kHz(or 0Hz) = collision
