◆ 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 if far away with the sensor

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

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

characteristic curve of AH413 is shown as the figure:
