Product Description

 Outline
AH3021 (2) is a bipolar high sensitivity Hall effect magnetic sensor which is made by BiCMOS technology (Hall effect digital intergrated circuit. It includes voltage regulators, Hall voltage generator, signal amplifier, Schmitt trigger , temperature compensation circuit, and open collector output driver circuit etc. It's suitable for working in unipolar and multipole magnetic field, and it's extensively used in all kinds of electromechanical integration fields.
  Function Description
 
When a "S" pole or "N" pole magnetic field is approaching to the front of the circuit, the output level of the circuit changes from high to low or from low to high, if the field is far from the circuit, the output status maintains constant, only when "N" pole or "S" pole (opposite with the pole of the initial magnetic field) field is approaching again, the output status of the circuit jumps back to original status. It means a complete circle of the circuit's operation needs a pair of magnetic field.

Note 1:
 When the sensor is used, all the above specified parameter range can't be exceeded, and it can't be used for a long time when the parameter is approached.
  Before the user is using the product, please detailed know the product's characteristic and attention, or to install and operated after guided by professional persons, to ensure the products' reliable operation in long term.
  In order to avoid mechanical stress affect the circuit internal chip, the part which is 1mm to the foot of the pin can't be bended, and the foot of the pins should be fixed when the other part are bended or shaped.
