Attachment and assembly
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 “Fig. 8”).
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 reso-
lution, 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°.
