What is the distance between the mounting plate 10 on which 3 is attached and the rotating shaft 2, and (2
) The distance between the Hall IC 12 and the printed circuit board 13 can be controlled to a predetermined value. Therefore, the distance between the magnet 5 and the Hall IC 12 is 0.3 mm to 0.8 ml I++2. Attachment only (-
Therefore, if the printed circuit board 13 (:) is to be fixed, the distance between the Hall IC 12 and the printed circuit board 13 is not fixed, but since the mounting tool 16 is provided, the distance can be set to -y.
