That cross patterned face is then a target to be machined

Maybe, or just a place for epoxy to bond to. That face with
the cross indentation is where the bias magnet is,
The flat face nearest the leads is where the actual sensor
chip is.
I'm in the house but I now seem to recall that its the
smooth side that's facing the gear in the lathe.
Yes, that's the only way it would work.
Duh. It takes a 16mm projector lens and damned strong
light to read the text printed on the "branded face". What
the hell were they thinking? You're saying that the
depressed cross in the 5% smaller face is not the sensed face?
Yes.
That the crossed pattern should be the face glued to the
mount?
Yes.
In that event I also have them wired reversed polarity.
Which shouldn't hurt them as they are rated for up to 18
volts of reversed voltage.
Oh, that will make it even less likely to sense anything.
