It operates from a 4.5 V supply rail and delivers a current-source output rated at 16.8 mA switching current, enough to drive a small relay coil or a PLC input directly without a buffer transistor. ## Temperature Grade and Environment Fit Rated for -40°C to 125°C (TA), the TLE4941CN covers automotive under-hood and industrial outdoor enclosures where the ambient temperature swings wide. The through-hole package (Bulk) is a practical choice for prototyping or low-volume production – the leads are robust enough to survive a rework cycle without lifting a pad. ## Sourcing Reality – Active Production, No Obsolescence Pressure No last-time-buy deadline or successor part is recorded.","metaTitle":"TLE4941CN Hall Effect Sensor – Infineon, Active","metaDescription":"Infineon TLE4941CN Hall effect magnetic switch, through-hole, current source output, detects both north and south poles.
