Description of product


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 which actively suppresses vibration while keeping excellent airgap performance. 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.
