Cummins 3615650-KC9H0 Exhaust Gas Temperature Sensor

This exhaust gas temperature sensor (EGT) is designed for integration within the selective catalytic reduction (SCR) aftertreatment system of heavy-duty commercial vehicles. The sensor utilizes a high-temperature thermistor element housed in a stainless steel probe assembly to measure exhaust gas temperatures up to 900°C. The sensor provides critical feedback to the engine control module (ECM) for catalyst light-off management, DPF regeneration control, and thermal protection of aftertreatment components. The assembly includes a sealed connector interface compliant with automotive environmental standards (IP69K) and a threaded mounting boss for direct installation into the exhaust pipe or catalyst inlet/outlet. The part serves as a direct replacement for Dongfeng service numbers 3615650-KC9H0, 3615650-T25F0, 3615650-TF980, and 3615650-TF680, cross-referencing Cummins engine service part 4326893 and A046P415.
