The motor was opened at some point, and some of the sensors got squished a little, so I didn’t know how they were originally, or if it even mattered.That is not a part number I can find. Here's a TI part: http://www.ti.com/lit/ds/symlink/dr...l-digikeymode-df-pf-null-wwe&ts=1590355212167
On one side you will be closer to the sensor. On the other side, further away. It may or may nor make a difference, but why change from what the manufacturer did?
You know I never gave that a thought till you just mentioned it. I mean my entire life it never crossed my mind shoe laces work both ways. While like you I never used them in such a manner I have worked with some hall sensors where the opposite side was sensitive to the opposite pole. I have some old discontinued 4 wire Allegro chips which go high on one wire for one pole and high on another wire for the other pole. I always liked them and can't figure out why they were discontinued.The point I tried to make was, "it depends." Yes, they will detect something from both faces. But most people use the designated face, In fact, I have never seen an application where that wasn't the case.
It's a little like lacing shoes, You can go bottom to top (the usual way) or top to bottom. Both ways work, but the performance will be different.
