The MAQ470 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 0rpm to 60,000rpm.
The MAQ470 supports a wide range of magnetic field strengths and spatial configurations. Both end-of-shaft and off-axis (side-shaft mounting) configurations are supported. The device 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 the 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, and magnetic field detection thresholds.

TBMAQ470-Q-LT-01A Evaluation Kit Long Evaluation Board for the MAQ470
The TBMAQ470-Q-LT-01A is the long evaluation board for the MAQ470 MagAlpha magnetic position sensor. The sensor is mounted to the edge of the board for 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 (RD) version, in which the sensor is mounted in the center of the board for end-of-shaft configurations.
