SPH3A0 series positive and reverse tachometric transduce is detected by Hall principle, which only needs to fix two corresponding magnets on the axis and wheel (two magnets are distributed symmetrically, and the N pole of one magnet must face to the sensor, and the S pole of the other magnet must face to the sensor), and fix the arrow of the detection surface of the sensor probe to face the arc of the magnet rotation.
When the wheel or axis rotates, the magnet sweeps the sensor probe along the direction of the arrow, Line 2(blue line) outputs positive rotation signal (low level), Line 4(white line) outputs positive rotation speed pulse signal; conversely, Line 2(blue line) outputs reverse rotation signal (high level), Line 4(white line) outputs reverse rotation speed pulse signal.
