MA302GQ-P

MA302GQ-P is a digital, contactless angle sensor with ABZ and UVW incremental outputs. The MA302 detects the absolute angular position of a permanent magnet, typically a diametrically magnetized cylinder on a rotating shaft. The MA302 supports a wide range of magnetic field strengths and spatial configurations. Both end-of-shaft and off-axis (side-shaft mounting) configurations are supported. The MA302 features magnetic field strength detection with programmable thresholds to allow sensing of the magnet position relative to the sensor for creation of functions such as sensing of axial movements or for diagnostics. On-chip non-volatile memory provides storage for configuration parameters, including the reference zero angle position, ABZ encoder settings, UVW pole pair emulation settings, and magnetic field detection thresholds. Typical applications include brushless DC motor servo drives, motor commutation, motor speed and position control, robotics.
