Sentron 2SA-10G 2-axis Linear Hall Magnetic IC

Sentron’s magnetic angular sensor 2SA-10G detects the absolute angular position of a small magnet that is positioned above the device surface.

The 2SA-10G 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-10G is ideally suited for rotary non contact position sensing in harsh 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.

The 2SA-10G-SO is RoHS compliant.

The 2SA-10G positioned under a rotating magnet provides exact angle and rotation direction information. The angle may be computed from Sx and Sy, and the direction is known from which signal (Sx or Sy) leads
