Infineon Technologies TLE4953C Magnetic Speed Sensors

Infineon TLE4953C Magnetic Speed Sensors detect the direction and meet the needs of high-end transmission applications. The TLE4953C offers jitter performance and high sensitivity for high-accuracy systems with excellent vibration suppression. Adaptive hysteresis and the dynamic self-calibration algorithm ensure outstanding measurement results with both fine and coarse target wheels. The south and north poles can be pre-inducted. The TLE4953C features a current interface and comes in a two-wire package with an integrated 1.8nF over molded capacitor for improved EMI performance.
