MA800 8-Bit, Digital, Contactless Angle Sensor with Push Button Function

Product Detail

The MagAlpha MA800 is a simple-to-use, digital, magnetic sensor designed to replace analogic potentiometers or rotary switches. The sensor detects the absolute angular position of a permanent magnet attached to a rotating shaft. Since the measurement is spatially confined, the user has flexibility in terms of magnet shapes and configurations. Typically, the MA800 is used with a diametrically magnetized cylinder of 3mm to 8mm in diameter. The MA800 features programmable magnetic field strength thresholds which allow implementation of a push button function. These are readable via the register bits and also as output signals. On-chip non-volatile memory provides storage for configuration parameters including the reference zero angle position and the magnetic field detection thresholds.
