Infineon Technologies TLE4959C Transmission Speed Sensors
Infineon Technologies TLE4959C Transmission Speed Sensors provide information about rotational speed and direction of rotation to the transmission control unit. These sensors include a sophisticated algorithm to suppress vibration while keeping excellent airgap performance actively. The TLE4959C sensors consist of two integrated capacitors on the lead frame 220nF/1.8nF, which increases the EMC robustness of the device. These sensors feature high-magnetic sensitivity, adaptive hysteresis, three wire PWM voltage interface, and automotive operating temperature range.
The TLE4959C hall based differential speed sensors are also available in TLE4959C FX variant, which is a flexible transmission sensor.
