Hi,
Normally a Hall sensor will be sensitive to the polarity (N-S) of the magnetic field, but Reed Switches are not. [OT:] This may affect the operation of some anemometers such as the Fine Offset, which is intended to generate two pulses per revolution (but I don't recall exactly how the reed is positioned relative to the magnet).
Cheers, Alan.
