Sentron Angle Sensor, Linear 2-Axis Hall IC, 2SA-10G 
Tabs
 
Sentron 2SA-10 Analog Hall Device 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.

Features
Applications
  • Measures two components of a magnetic field at a single location
  • Excellent matching of sensitivities along the two axes.
  • Very high sensitivity
  • Low quiescent current
  • Fabricated in standard CMOS technology
  • Available in SOIC-8
  • 2-D position sensing
  • Contactless potentiometer
  • Angular position sensor for micromotors
  • Miniture contactless encoder
  • contactless rotary switch
  • 2-D magnetic field mapping
  • Joystick
  • 1-D linear position sensor

The "leaded" versions of the Sentron 2SA-10G-SO are no longer in production, the "leaded" parts are identified as not having "G" parts (2SA-10G-SO).

The Sentron CSA-10G-SO is manufacture by Melexis Semiconductors and is equivalent to the MLX91204.
