Operating Range and Hysteresis
Operating range: θm
The range is between the position where the auto switch turns ON as the magnet inside the auto
switch unit moves rotationally and the position where the auto switch turns OFF as the magnet moves
rotationally in the same direction.
Hysteresis range: θd
The range is between the position where the auto switch turns ON as the magnet inside the auto
switch unit moves rotationally and the position where the auto switch turns OFF as the magnet moves
rotationally in the opposite direction.

Auto Switch Adjustment
Rotation range of the output shaft with single flat (key for size 40 only) and auto switch mounting position.
 Solid-lined curves indicate the rotation range of the output shaft with single flat (key). When the single
flat (key) is pointing to the END ① direction, the switch for rotation END ① will operate, and when the
single flat (key) is pointing to the END ② direction, the switch for rotation END ② will operate.
 Broken-lined curves indicate the rotation range of the built-in magnet. Operating angle of the switch can
be decreased by either moving the switch for rotation END ① clockwise or moving the switch for rotation
END ② counterclockwise. Auto switch in the figures on the left is at the most sensitive position.
 Each auto switch unit comes with one right-hand and one left-hand switches.
