Melexis 3-Axis Surface Mount Position Sensor, SPI

The Melexis position sensor IC providing the absolute angular position of a small dipole magnet rotating above the device surface. This monolithic device senses, in a contactless fashion, the horizontal component of the applied magnetic flux density. This unique sensing principle applied to a rotary position sensor results into an impressive robustness of the angular position over the mechanical (air gap, off-axis) tolerances. The output transfer characteristic is fully programmable to match any specific requirement through end-of-line calibration. The Melexis programming unit PTC-04 communicates and calibrates the device exclusively through the connector terminals.
