AH35 Series Hall sensor is an analog signal outputs Hall IC, output voltage varies with the

intensity of the magnetic field. The sensor chip has built-in reverse voltage protection, voltage

regulators, temperature compensation circuit, Hall voltage generator, signal amplifier etc circuit

uint. Excellent voltage regulator and temperature compensation circuit enable the sensor stable

operation within a wide voltage range and temperature range, the reverse voltage protection circuit

avoids the sensor being reverse voltage damage.

Linear Hall effect Sensor magnetic and electric transfer characteristic:：

The Sensor will pass the linear zone/non linear zone/saturation zone during the period

when the magnetic strength increases: when no magnetic field applied on the sensor（B=0）,

the output of the sensor is about half of the Vcc（Vcc/2）； When “N” pole faces sensor’s

mark surface and be closed to it（B→-∞）, the output voltage of the sensor begins to reduce,

the voltage doesn’t reduce with the enhancing of the field when it reached saturation status;

when “s” pole faces the sensor’s mark surface and be closed to it （B→+∞）, the output

voltage begins to increase, and the voltage won’t increase with the enhancing of the field

when it reached saturation status. The linear Hall effect sensor magnetic and electric transfer

characteristic curve is shown as the figure:
