Infineon Technologies XENSIV™ TLE55493 Wheel Speed Sensors
Infineon Technologies XENSIV™ TLE55493 Wheel Speed Sensors measure rotational speed with high accuracy, enabling indirect Tire Pressure Monitoring Systems (iTPMS). Features include a wide linear range, robustness against magnetic field disturbances, and excellent sensitivity over a wide temperature range, meeting harsh automotive requirements for ESD and EMC. These magnetic sensors are AEC-Q100 Grade-qualified for automotive applications. The rotational speed is sensed with high accuracy and jitter performance. The TLE55493 sensors are ideal for anti-lock braking systems, indirect tire pressure monitoring systems, hill holders, electronic parking brakes, and autonomous parking.
