PEDAL ADJUSTING SENSOR

Description

INFOID:0000000005147541

• The pedal adjusting sensor is installed to the pedal assembly. 

• The resistance of pedal adjusting sensor is changed according to the forward/backward position of pedal

assembly.

• The terminal voltage of automatic drive positioner control unit will be changed according to a change of

pedal adjusting sensor resistance. Automatic drive positioner control unit calculates the pedal assembly

position from the voltage.
