Monolithic Power Systems MA700

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 MagAlpha is an extremely fast acquisition and processing sensor, allowing accurate angle measurement at speeds from 0 to 120’000 RPM.

Since the measurement is spatially confined, the user has flexibility in terms of magnet shapes and configurations. This can help relaxing mechanical tolerances and, in case the end of shaft position is not available, the MagAlpha 700 can also operate away from the axis of rotation (“side-shaft” mounting).
