Description
CAT 441-5129 Engine-Out NOx Emissions Sensor combines a NOx probe, cable assembly and electronic control enclosure. It measures engine-out nitrogen oxide and oxygen levels in real time, sends values through the SAE J1939 datalink and can diagnose probe-circuit shorts or open circuits. The unit uses a 6.5–16V supply, M20 x 1.5 thread, six-pin connector and approximately 35.4-inch lead. Public model fitment lists industrial engines and SCR retrofit systems; confirm any marine installation, sensor position, serial number and CAT SIS arrangement.
