Nernex 24-Volt Outlet NOx Sensor Technology

Nernex aftermarket NOx sensors are designed to provide the precise exhaust-gas measurement required by modern diesel aftertreatment systems. The sensor electronics communicate NOx concentration data to the vehicle control system to support proper Selective Catalytic Reduction (SCR) operation and continuous emissions monitoring.

This sensor is designed for the outlet / downstream position. At this location, the sensor measures exhaust NOx after treatment, allowing the vehicle control system to evaluate SCR efficiency and monitor NOx reduction.

Direct-Fit Replacement for Cummins 5462442 and 2872298

The Nernex 20.220347 NOx sensor is intended as a direct-fit aftermarket replacement for compatible applications using 5462442, 2872298, 1873793PE, or 2894946. Related Cummins NX and RX service numbers and PACCAR PE / PEX numbers are listed above to assist with part-number identification.

Because a truck model can use different NOx sensors depending on engine, model year, emissions calibration, voltage, and sensor position, always compare the number stamped on the original sensor before ordering. Confirm that the original sensor is a 24-volt outlet / downstream sensor and that the connector and vehicle application match.

Product images are for reference only. Always verify the original sensor/OEM number, sensor location, voltage, engine application, and connector configuration before installation.
