Cummins 4327239 Engine Speed Sensor

The Cummins 4327239 is a magnetic engine speed sensor designed to provide precise crankshaft or camshaft position signals to the engine control module (ECM). It features a corrosion-resistant housing with a magnetic pickup element, ensuring reliable signal generation in harsh heavy-duty environments. The sensor utilizes a screw-in mounting configuration for direct installation on Cummins QSK series engine blocks. Electrical connection is achieved via a 2-pin or 3-pin OEM connector depending on the specific engine configuration. This sensor serves as a direct replacement for Cummins part numbers 2872359 and 3408472, as well as Komatsu 6560-61-2110 and Hyundai HCE 3408472 cross references.
