MagAlpha MA700
Angular Sensor for Position Control
with Side-Shaft Positioning Capability
PRELIMINARY SPECIFICATIONS SUBJECT TO CHANGE
DESCRIPTION
FEATURES
The MagAlpha MA700 is a robust, contactless,
angle encoder. The IC detects the absolute
angular position of a permanent magnet,
typically a diametrically magnetized cylinder
attached to the rotor. The data acquisition and
processing is extremely fast, allowing accurate
angle measurement at speeds from 0 to
100,000 RPM
The MA700 supports a wide range of magnetic
field strengths and spatial configurations, which
help to relax mechanical tolerances and simplify
system design. Both end-of-shaft magnet and
off axis magnet positioning (side-shaft
mounting) topologies are supported.
