The MagAlpha MA3xx family 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 digital filtering is adjustable to optimize control loop performance when used in servo applications.
The Sensors supports a wide range of magnetic field strengths and spatial configurations. Both End-of-shaft and off-axis (side-shaft mounting incl orthogonal position) configurations are supported.
The featured 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.
