PEDAL ADJUSTING SENSOR
DescriptionINFOID:0000000005147541
• The pedal adjusting sensor is installed to the pedal assembly.
• The resistance of pedal adjusting sensor is changed ac cording 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 pos itioner control unit calculates the pedal assembly
position from the voltage.
