Transmission Speed Sensors

Transmission Speed Sensor (3-wire)

Stand-alone, contactless, active sensor providing the speed and direction of the transmission shafts by detecting the rotation of a ferromagnetic or magnetic encoder wheel mounted on the input and output shafts.

Stand-alone, contactless, active sensor providing the speed and  direction of the transmission shafts by detecting the rotation of a  ferromagnetic or magnetic encoder wheel mounted on the input  and output shafts.

Speed signal is required by the Transmission Control Unit (TCU) to  control the transmission system, adjusting properly the shaft  speeds before engaging and disengaging the different gears.
