The MagVector™ MV2 is the ideal solution if you need to integrate a sophisticated magnetometer into your electronic system. A typical application would be a sensor array for a custom magnetic field mapping system. The MV2 was developed by MPS Tech Switzerland Sàrl (formerly Sensima Technology SA) in cooperation with Metrolab. Metrolab uses the same sensor in several of its products and is now making this technology available to electronic system designers.

It is worth noting that, as an electronic peripheral component, the MagVector™ MV2 does not come with any of the amenities of a traditional magnetometer: the user must provide the microcontroller, control firmware, host interface, user interface, and calibration. For full-featured three-axis Hall effect magnetometers, please refer to the THM1176 / TFM1186 instrument family.
