motion sensing solution Infineon TLE4966K Hall effect sensor with digital speed and direction output
High Precision Hall-Effect Switch with Direction Detection
Product Overview
The TLE4966K is a high-precision Hall-effect sensor designed for applications requiring accurate speed and direction detection. It features a wide supply voltage range (2.7 V to 24 V), operation from unregulated power supplies, and exceptional stability of magnetic switching points due to active error compensation and chopper techniques. The device provides a speed signal and a direction signal, with the direction signal outputting before the speed signal. Its robust design ensures high resistance to mechanical stress, superior temperature stability, and peak temperature tolerance up to 195C. The TLE4966K is ideal for applications demanding precise motion sensing and directionality.
