The MLX90384 is a high-precision magnetic position sensor for robotic joints. Featuring Arcminaxis™ technology, it comes with as a four-component set:
|
1) A sensor chip with two monolithic magnetic position sensor ICs, each consisting of a Triaxis® Hall magnetic front end, analog-to-digital converter, hardware for high-speed signal conditioning, and a 10MHz high-speed SPI interface. The ICs are both configured to be sensitive to a first magnetic flux density component parallel to the chip and to a second component perpendicular to the chip. |
2) A Vernier-type magnet, with two tracks of eight and seven pole pairs. The MLX90384 sensor chip measures the axial and tangential magnetic components of both tracks and transmits this information to a microcontroller. |
