Product Information

Board Mount Hall Effect / Magnetic Sensors 10-bit, digital, contactless angle sensor with ABZ incremental & PWM outputs

The MA704 detects the absolute angular position of a permanent magnet, typically a diametrically magnetized cylinder on a rotating shaft. The MA704 is particularly suited to track highly dynamic movements with speeds up to 60’000 rpm.

The MA704 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 MA704 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
the 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, and magnetic field detection thresholds.
