IC Details

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.

IC Details

The EVKT-MACOM is a communication kit for the MagAlpha magnetic position sensor family. The EVKT-MACOM offers a seamless connection and operation with MagAlpha test boards (TBMA) and evaluation kits (EVKT-KNOB). The kit contains a microcontroller motherboard, a collection of daughter boards adapted to different sensor boards and the related cables.
