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.

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

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.
