Definition of the Hall effect: When a current passes through a bar of semiconductor (or conductive) material, and if an induction magnetic field B is applied perpendicularly to the direction of current flow, a voltage, called the Hall voltage, proportional to the magnetic field, and the current appears on the side faces of the bar.
This voltage is proportional to the speed of movement of the charge carriers, It is considerably higher in semiconductor materials than in metal conductors. Magnetic Sensor Characteristic: - Input Voltage: 3.8-30VDC - Output current: 40mA
High output current capacity -40 mA maximum absolute
Quad-Hall design virtually eliminates static mechanical effects
Magnetic compensated temperature - Digital current sinking output
