The MA310 detects the absolute angular position of a permanent magnet, typically a diametrically magnetized cylinder on a rotating shaft. Fast data acquisition and processing provide accurate angle measurement at speeds from 0 to 60,000 rpm.
The MA310 is particularly suitable for low magnetic field applications: side-shaft configuration or the use of non-rare earth magnets.
The MA310 features magnetic field strength detection with programmable thresholds to allow sensing of the magnet position relative to the sensor for creation of functions such as sensing of axial movements or for diagnostics.
On-chip non-volatile memory provides storage for configuration parameters including the reference zero angle position, ABZ encoder settings, UVW pole pair emulation settings, and magnetic field detection thresholds.

TBMA310-Q-LT-01A Evaluation Kit Long Evaluation Board for the MA310
The TBMA310-Q-LT-01A is the long evaluation board for the MA310 MagAlpha magnetic position sensor. The sensor is mounted on the edge of the board, and can therefore be used in both side-shaft and end-of-shaft configurations.
It requires the EVKT-MACOM communication kit and the Macom App Software to evaluate MagAlpha functionality and performance with the set-up, such as noise level, refresh rate, start-up time, and magnetic field dependence.
In addition to this long (LT) evaluation board, there is a round format (RD) version, in which the sensor is mounted in the center of the board for end-of-shaft configurations.
