DESCRIPTION

The MA710 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 MA710 is particularly suitable for low magnetic field applications: side-shaft configuration or the use of non-rare earth magnets.

The MA710 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.
