"Double hall, speed and direction output" has two hall elements arranged in the plane direction of the package, and has two outputs. One outputs the change in magnetic flux as a linear voltage, converts it to a pulse with an internal comparator, and outputs it as a pulse. The other compares the sensing timing of each Hall element and sets the output to High/Low depending on the direction of rotation.

"Double hall, two independent outputs" similarly has two hall elements (in the same direction as the package) arranged horizontally and has two outputs. The sensing result of each Hall element is output as a pulse.

In "Vertical double hall, speed and direction output", the direction of the Hall element is different from the above two, and two Hall elements in the direction perpendicular to the package plane are lined up in the package plane direction. There are two outputs, one of which outputs the sensing result of one Hall element in pulses. The other compares the sensing results of the two Hall elements and sets the output to High/Low depending on the direction of rotation.
