Product Overview
The TLE4966K is a high-precision Hall-effect switch 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 high stability of magnetic switching points due to active error compensation and chopper techniques. This bipolar device provides digital output signals for both speed (Q2) and direction (Q1), with the direction signal switching prior to the speed signal. Its robust design offers superior temperature stability, resistance to mechanical stress, and reverse battery protection, making it suitable for demanding industrial environments.
