DM-232 - Sony Corporation

DM-232 Magnetoresistance Element

DM-232 a magnetic sensor using magnetoresistance effect is composed of ferromagnetic material deposited by evaporation on a silicon substrate. It is suitable for angle of rotation detection. Features • Low magnetic field and high sensitivity: bridge type stands for large output voltage 150 mVp-p (Min.) at VCC=5 V, H=14400 A/m • Fitted with bias magnet: stabl.
