Working Principle -
The UGN3501 operates based on the Hall effect where a voltage is generated when a magnetic field is applied perpendicular to the sensor. The internal amplifier converts this small Hall voltage into a proportional analog output. The output voltage increases or decreases depending on magnetic field strength and polarity, enabling precise non contact sensing.
