KBA_SENS_0505: How do hall-effect sensors compare to other sensors based on magneto-resistance effects?

Hall-effect sensors are inherently more linear and do not have “hysteresis” effects from strong magnetic field. Some magneto-resistance sensors can be damaged by very strong field.
Magneto-resistive sensors are generally sensitive in the direction of magnetic field parallel to the PCB. In most cases, it is possible to order the magnet with a different polarization to produce magnetic field in the desired axis.
