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.
