MagAlpha MA710
12-Bit, Digital, Contactless Angle Sensor
with ABZ Incremental & PWM Outputs
DESCRIPTION
FEATURES
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.

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.
