AH3144 Hall Sensor

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:

Rated working voltage 4.5 V ~ 24 V, the limit voltages as low as 3.5 V;

Hall Sensor Operating temperature range: - 40℃ ~ 150℃;

Hall Sensor Rated output current(sink) : 25 mA, the maximum output current(sink): 50 mA;

Hall Sensor Switch response time is about 1μs, the operating frequency DC ~ 100 kHz;
