TLE492x Magnetic Speed Sensors Infineon TLE492x Magnetic Speed Sensors are designed for a broad range of speed sensing applications. Each sensor provides the highest levels of quality, robustness and cost efficiency. The TLE92x have hysteresis and dynamic self-calibration algorithm. This algorithm makes the sensors ideally suited for high-performance speed sensing applications in harsh environments. These environments include automotive engine or transmission applications. All sensors have a three-wire voltage interface, fast start-up time, symmetrical switching thresholds and optional south or north pole pre-induction.
