High accuracy speed and position sensor Infineon TLE4929CXANM28HAMA1 with magnetic stray field robustness
Product Overview
The TLE4929C is a fully programmable, active Hall effect crankshaft sensor designed for high-accuracy speed and position measurement in automotive and industrial applications. It offers low jitter capabilities, magnetic stray-field robustness, and a digital output signal with programmable protocols and a diagnosis interface. The sensor supports direction detection and Stop-Start algorithms, making it ideal for crankshaft applications, speedometers, and other speed-sensing requirements where precision is critical. Its end-of-line programmability allows adaptation to specific engine parameters, and it can also function as a differential camshaft sensor.
