- 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 magnet is far away from the sensor(B≤ BRP), the sensor outputs high level. When the "N" pole faces to sensor's mark surface of sesor, the sensor is no response. Stable hysteresis (BH= ∣BOP- BRP∣) ensures stable switch status of sensor. The magnet and electric transfer characteristic curve of AH3621 is shown as the figure:
- Hall sensor AH3621 is a kind of digital output Hall IC which produced by CMOS Technology. The sensor chip is produced by CMOS technology, it owns low power consumption, and it has built-in reverse voltage protection, voltage regulators, temperature compensation circuit, Hall-voltage generator, signal amplifier, Schmitt trigger, and output driver and other circuit unit etc. Excellent voltage regulator and temperature compensation circuit ensure the sensor stable operates over a wide voltage range and temperature range, and the reverse voltage protection circuit avoids the sensor to be damaged by reverse voltage.
