Product Information

The MagAlpha MA850 is a simple-to-use magnetic angle encoder designed to replace analog potentiometers or rotary switches. The sensor detects the absolute angular position of a permanent magnet attached to a rotating shaft and outputs a PWM waveform with 8-bit resolution.

The user has wide flexibility in terms of magnet shapes and configurations. Typically, the MA850 is used with a diametrically magnetized cylinder of 3mm to 8mm in diameter. 

The MA850 features programmable magnetic field strength thresholds which allow implementation of a push or pull button function. When triggered, these are readable as register bits and also output as two logic signals.

On-chip non-volatile memory provides storage for configuration parameters including the reference zero angle position and the magnetic field detection threshold settings.
