Product Description

Features Rated working voltage 4.5 V ~ 24 V, the limit voltages as low as 3.5 V;Operating temperature range: -40ºC ~ 150ºC; Rated output current(sink) : 25 mA, the maximum output current(sink): 50 mASwitch response time is about 1μs, the operating frequency DC ~ 100 kHz;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  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 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 AH3144 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.
