Digital Unipolar Hall IC 10 Magnetic Behavior South Pole Active When the S pole of the magnet faces the mark surface of the sensor and is close to it (B≥BOP), the sensor outputs a low level; when the S pole is away from the sensor (B≤BRP), it outputs a high level. The sensor does not respond when the N pole faces its mark surface. The stable hysteresis (BH = | BOP - BRP |) ensures that the sensor switch is stable. The magnetoelectric conversion characteristics of AH3144 are shown in the figure: Vout switch to high Switch Type South Pole Active Nanjing AH Electronic Science & Technology Co.,...
