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

Accessories

AN_114KIT (STD. PCB) 360° Angle Sensing Reference Design Kit

This kit is useful for evaluating the 2-Axis linear Hall Effect sensor in Angular Position sensing applications. The kit contains an assembled printed 0.5" x 1.0", circuit board with a 2SA-10G-SO soldered onto the PCB, a magnet guide, a SmCo magnet that has been magnetized across the diameter and an extra 2SA-10G-SO sample part. The plastic guide fits into four holes on the PCB and provides a means of centering the magnet over the IC and providing the optimum spacing between the magnet and IC. As the magnet is manually rotated 360 degrees, the X and Y outputs will provide a sin and cosine voltage output at the X and Y outputs respectively

GSM360A

GMW Sin/Cos to Analog Interpolator IC - GMW360A

The GMW360A Interpolator IC is designed to be compatible with the Sentron 2SA-10G, 2-Axis angular sensing IC, however it will work with any SIN and COS signal input with the required input amplitude. The GMW360A is based on the Cypress PSoCTM, CY8C24123A, Mixed-Signal Array device. The GMW360A converts orthogonal SIN and COS signals to Analog and PWM output signals proportional to the angle with 9 bit resolution.
