AH3144 Hall Sensor
3144 Hall Effect sensor 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 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
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;
