What the TLE4928CE6547 is and where it fits
The TLE4928CE6547 is a magnetic switch speed sensor from Infineon, designed for rotational speed detection in harsh environments. It senses both North and South magnetic poles, which means the magnet orientation on the target wheel is not critical — the sensor triggers on either polarity. The through-hole mounting package (Bulk) suits applications where vibration resistance and mechanical retention matter more than board density — think engine-speed sensing, transmission output, or camshaft position in automotive powertrains. The -40°C to 175°C operating range is the headline spec: it covers under-hood and transmission-bay temperatures where many commercial-grade sensors would fail. A 175°C junction rating means the sensor can sit on a hot engine block without derating.
Active production status and sourcing
For a BOM line that needs this exact speed sensor, there is no forced migration risk today. Sourced per RFQ against your quantity; no stock-holding claim, but the active status means lead times are typically standard for Infineon through-hole sensors.
Package and mounting
Because the sensor responds to both North and South poles, you can use a simple two-pole magnet wheel without worrying about pole alignment. The output switches on each pole transition, giving one pulse per magnetic pole pair — useful for speed measurement where you want a clean digital edge per rotation segment. The through-hole package has three pins: supply, ground, and output.
