2SA-10 - SENTRON

2SA-10 Integrated 2-Axis Hall Sensor

Sentron’s new 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.
