Sentron Angle Sensor, Linear 2-Axis Hall IC, 2SA-10
 |
| |
Sentron's magnetic angular sensor 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 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-10 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.
