  • Small temperature drift between operating point and release point;
  • There are variety of packages and out packing options;
  • No mechanical contact, no spark, switch signal stability, no shaking moment, high reliability and safety;
  • Products meet the EU RoHS instruction 2011/65 / EU and REACH regulations 1907/2006 / EU requirements
  • Outline
  • When the "N" pole of magnet faces the mark surface of the sensor and is closed to sensor (BBop),the sensor outputs low level; When the magnet is far away from sensor(BBRP), the sensor outputs high level. When the "S" pole faces the mark surface of sensor,the sensor is no response. Stable Hyteresis((BH= |BOP- BRP|)ensures stable switch status of sensor. The magnet and electric transfer characteristic curve is shown as the figure:
  • Hall sensor AH3144N 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.
