Hall Effect Sensor Manufacturer
AH3662 Hall Effect Sensor is an Omnipolar micro-power high sensitivity Hall effect sensor, special designed circuit make it owns omnipolar(regardless S pole or N pole) magnetic field excitation function, excellent symmetry of the positive and negative magnetic switch, and very small average current consumption characteristics.
When the magnet(regardless S pole or N pole) is closed to sensor（︱B︱≥︱Bop︱），the sensor outputs low level; When the magnet is far away with the sensor（︱B︱≤︱Brp︱）, the sensor outputs high level. Stable hysteresis （Bhx =︱Bopx--Brpx︱）enables the sensors stable switch state. The sensors' magnetic and electric transfer characteristic curve is shown as the figure:
Rated working voltage 2.4V ~ 5.5V,
Work under Omnipolar, the excitation field regardless of N or S pole, high magnetic sensitivity, highly symmetric of positive and negative magnetic switching points;
Built-in dynamic offset voltage compensation circuit, high temperature stability, small drift switching point, resistance to mechanical stress and thermal stress;
Ultra small power consumption, it’s only 8μW when the power supply is 2.75V
