◆ 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 the ―N‖ pole faces the mark surface and is

closed to sensor（B≤Brp），

the sensor outputs high level. When the magnet is far away from the

sensor (B=0), the output status of the sensor is latched and keeps constant. In order to change

the output status, the applied magnetic field must be opposite polarity. The magnet and electric

transfer characteristic curve of AH3012 is shown as the figure:
