XENSIV™ - TLE4941C magnetic speed sensor with dynamic self-calibration principle Infineon XENSIV™ TLE4941C provides information about rotational speed to modern vehicle dynamics control systems and ABS. The output has been designed as a two wire current interface. The sensor operates without external components and combines a fast power-up time with a low cut-off frequency. Excellent accuracy and sensitivity is specified for harsh automotive requirements as a wide temperature range, high ESD and EMC robustness.
