Sensors
Road speed display
An impulse sender wheel milled in the differential housing generates the signals that speedometer sender G22 requires to determine the actual road speed of the vehicle.
Speedometer sender G22 is inserted in a drill hole in the gearbox housing from the outside.
The sender operates according to the Hall sender principle. The electrical impulses generated by the sender are transmitted to the control unit in the dash panel insert. Here, the signals are conditioned for the actual road speed and mileage display.
Advantage: Ultra-high display accuracy, smooth running, temperature resistant.
