Well, clearly, you would look for a local vendor. I am just pointing out
that the stuff exists.

5 bucks a meter? A week to ship ARO? They obviously aren't "hungry".
Based on buying some cutting tools from a limey vendor a year ago, I'll
be 6 weeks getting it into my hands. Nyet.

I think the RC filter idea would work OK. Gear teach are after all a
low frequency signal, so a filter made with a cap size for a corner
freq of (say) 100KHz will keep RF out of the line.
That said the "correct" way to do this is with a pair of
driver/receiver chips. If you use RS422 (that is a

Greetings all;
I see by the spec sheet that the allegro 667 gear sensor can sink up to
25 mills.
But with 3 such sensors on the end of a long cable back to the breakout
