MA302

12-Bit, Digital, Contactless Angle Sensor with ABZ & UVW Incremental Outputs

Datasheet

Description

The MA302 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 MA302 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 MA302 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.

TBMA302-Q-LT-01A Long Evaluation Board for the MA302

The TBMA302-Q-LT-01A is the long evaluation board for the MA302 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.
