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 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 is shown as the figure:
