The HMC1501 and HMC1512 position sensors have the ability to measure the angular direction verses the strength and direction of a magnetic field. These devices feature a wide range of resolution, as shown in this slide, and offer a linear range of 8mm with two sensors mounted on opposing sides with the option of adding more sensors to increase range and resolution. Additionally, these sensors offer low power consumption, large signal output, and are a higher precision alternative to hall-effect devices.
