DESCRIPTION
The MAQ430 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 MAQ430 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 MAQ430 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.
