A Sensor Rotor is designed to measure and detect the rotational speed of the object. It consists of a series of teeth evenly distributed around its circumference. These teeth are designed to generate electrical signals as they pass by a speed sensor. It is typically mounted on the input shaft of the torque converter and rotates along with it.Attributes:• Hardened with carbonitride of RKW 15N to exhibit excellent wear resistance• Manufactured to precise specifications and are built for durability and reliabilityApplications:A Sensor Rotor is used to provide accurate speed signals to the transmission control module or engine control unit of a vehicle, to precise specifications, and is built for durability and reliability.
