PRODUCTS DETAILS

◆ 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 away 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:

Hall sensor AH3142 is one of unipolar excitation single-ended digital output Hall IC. The sensor chip has built-in reverse voltage protection, voltage regulators, temperature compensation circuit, Hall-voltage generator, signal amplifier, Schmitt trigger and open collector output driver 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.
