To further demonstrate the benefit of designing a system for angular measurement using a 3D sensor with sensitivity correction, we will also attempt an off axis configuration and measure the exact angle of the magnet as it rotates. For this effort, we want to place the sensor at the outer edge of the magnet similar to what is shown in Figure2-5.

In this configuration, we will use the same magnet from the push-button knob, but will mount it to a motion controller that can accurately drive angular position. Here we can determine the exact performance of the configuration.

For this analysis, we will use the ±50 mT range and again target 90% full scale as a peak input value.
