2SA-10 detects the absolute angular position of a small magnet that is positioned above the device surface. The 2SA-10 is an integrated combination of a CMOS Hall circuit and a thin ferromagnetic disk. The CMOS circuit contains two pairs of Hall-elements for each of the two directions parallel with the chip surface X and Y. The ferromagnetic disk amplifies the external magnetic field and concentrates it on the Hall elements.
The 2SA-10 is ideally suited for rotary position sensing in harsh automotive and industrial environments. It produces two linear, ratio-metric output voltages proportional to the sine and the cosine function of the angle of the applied magnetic field parallel to the chip surface. |
