Figure 15: Assembling the lever
The gap between the driver pin and the axle should be the same as the drive stroke. This results in the
ideal angular range of the lever of 60° (see “Figure 16”).
angular range of the position sensor:
The maximum angular range of the position sensor is 180°.
rotational range of the lever:
To ensure that the position sensor operates at a good resolution, the rotational range of the lever must be
at least 30°.
The rotational movement of the lever must be within the position sensor angular range of 180°.
The scale printed on the lever is not relevant.
60°
Ideal angular range
of the lever = 60°
(min. 30° / max. 180°)
The swivel movement of the lever must be
within the position sensor slewing range of
180°.
