Direct-fit NOx sensing for heavy-duty applications

The PEX 193NOX2002 NOx sensor is designed for diesel exhaust systems to monitor and control nitrogen oxide emissions in demanding duty cycles. It replaces the Continental 5WK96749B reference and is associated with selected Cummins applications based on retailer categorization. Engineered in Germany with high-grade materials, the sensor supports emissions compliance and engine efficiency while standing up to heat, vibration, and contaminants typical of truck and bus environments. Built to OEM standards, it offers plug-and-play compatibility with OE-style connectors to streamline service and reduce downtime.

Designed for reliability and compliance

The sensor provides an electrical signal—typically a current or voltage—proportional to measured NOx concentration, enabling precise ECU control of aftertreatment functions. Fast response characteristics help stabilize feedback to minimize emission spikes during transient operation. Heavy-duty variants commonly integrate a heater for rapid warm-up, allowing the system to reach stable readings sooner; confirm configuration by OE number. With robust construction and reliable signaling, the PEX 193NOX2002 is a practical choice for fleets maintaining emissions systems on trucks, buses, and other heavy vehicles where the 5WK96749B cross-reference applies.
