Product Description

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?00 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 (?ide-shaft?mounting) topologies are supported.
