There is a AMR position sensor of KMXP2000 that is able to be using on the magnetic ruler end equipment. Beside, does TI have similar solution? is TMAG6180 workable?

Below is how to setup the magnetic sensor in the magnet field. How TMAG6180 works with this setup?
Brian,
We have not encountered many user's looking to implement the TMAG6180 in this way yet, but we have run a crude preliminary test with the device mounted alongside a magnetic strip tape mounted to a motion controller.
Using a tape with 2mm pitch we were able to observe the following as the mover drove along a 60 mm distance while using the TMAG6180-6181EVM
We see a fairly linear response with the main source of non-linearity coming from the acceleration of the mover as it began moving from a stopped condition.
The PCB was mounted above the magnetic tape with a very small air gap
Thanks,
Scott
