Accurate, Versatile Angle Position Sensors with Push-Button Detection

Fast, Accurate Angle Sensing for Space-Constrained Applications

This compact sensor knob demo displays the accuracy and flexibility of the MagAlpha family of magnetic angular position sensors. These sensors provide revolutionary performance and versatility for a wide variety of applications, including absolute angle detection and HMI buttons and knobs. MagAlpha sensors use MPS’s patented SpinAxisTM Hall measurement technique, which provides instantaneous digital angle position and uses phase detection to eliminate the need for complex angle calculations.


  • Supports on-axis (end of shaft) and off-axis (side-shaft) placement
  • On-axis configuration also supports button-press detection
  • Available in a tiny, 2mmx2mm or 3mmx3mm QFN package, these are the smallest solutions on the market
