The sequence of the phases A-B is obtained connecting the motor with the polarities printed on the black bottom cover.

HALL-EFFECT SWITCHES

These Hall-effect switches are highly temperature stable and stress-resistent sensors best utilized in applications that provide steep magnetic slopes and low residual levels of magnetic flux density. Each device includes a voltage regulator, quadratic Hall voltage generator, temperature stability circuit, signal chopper stabilized amplifier, Schmitt trigger and an open drain mosfet on a single silicon chip.
The on-board regulator permits operation with supply voltages of 3,5 to 24V. The output mosfet can sink up to 20 mA with suitable output pull up, they can be used directly with bipolar or MOS logic circuits.
