Hi Dave,
Try 4O3A, Ranko has several items. His azimuth magnetic sensor runs only €100
and works with CAT cable and an app. See:

A problem we have with our TIC ring is that the big gear isn't exactly
concentric, and it often skips a tooth or two in the wind. This offsets
the pot, making it vulnerable to running up against the end and being
damaged. So we can't count on the pot, and are hoping to find a way to
adapt either a Hall-efect tooth counter for the ring gear, or an
inexpensive electronic compass sensor.
Over the years we have damaged the coax by going beyond the rotation
limits when the pot is messed up (we use RT-21s with limits, but that
relies on the pot), and are intending to install IP67 limit switches as
well. We also need limit switches for our prop-pitch installations, just
to be sure we have redundant physical limits.
Open to any indicator suggestions, and suggest not to rely only on the pot.
Dave, W6NL/HC8L
