Product Description

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 mA
Switch 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 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 of AH441 is shown as the figure:
Hall sensor AH441 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 drives circuit unit. 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.
