MA730

14-Bit, Digital, Contactless Angle Sensor with ABZ Incremental & PWM Outputs

Datasheet

Description

The MA730 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 measurements at speeds from 0 to 60,000 rpm.

The MA730 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 MA730 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.

TBMA730-Q-LT-01A Long Evaluation Board for the MA730

The TBMA730-Q-LT-01A is the long evaluation board for the MA730 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.
