TLE4953 E0184
XENSIV™ - TLE4953 E0184 magnetic speed sensor for high-end transmission applications
Infineon´s XENSIVTM differential Hall magnetic speed sensor TLE4953 can detect direction and was developed specifically to meet the needs of high-end transmission applications in the automotive and industrial markets. The sensors´ jitter performance as well as high sensitivity enables designers to create 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. As with other Infineon speed sensors, the south and north poles can be pre-inducted. Our TLE4953 features a current interface and comes in a two-wire package with an integrated 1.8 nF overmolded capacitor for improved EMC.
