Outline
When the S pole of magnet faces the mark surface of the sensor and is closed to sensor(B≥Bop),the sensor outputs low level; When magnet is far away from sensor(B≤BRP), the sensor outputs high level. When the N pole faces the mark surface,the sensor is no response. Stable Hysteresis((BH= |BOP- BRP|)ensure the stable sensor's switch status. The magnet and electric transfer characteristic curve of AH441 is shown as the figure:

 Note 1: Unit is mT, 1mT=10Gs
 Note2:  When the "S"Pole of the magnetic field is vertical to the front mark of product, we call the magnetic field B>0.
 Note 3: For M type ( SOT23-3L) product, the operating magnetic field is subject to "N" pole.
