Collection: Nitrogen Oxide (NOx) sensor

Nitrogen oxide (NOx) sensors, organized by part number. NOx sensors monitor nitrogen oxide levels in the exhaust stream so the SCR aftertreatment system can dose urea correctly and keep emissions within Euro 5 / Euro 6 limits. This collection covers our full range of OEM-quality replacement NOx sensors — more than 340 part numbers, complete sensors and probes.

Coverage across truck and machinery brands

You will find sensors for Cummins, Volvo, DAF, Iveco, Isuzu, Case IH, Ford, Volkswagen, Hyundai/Kia and other applications, listed under the original part numbers with their 5WK9, SNS and 028 cross references shown on each page. Search the number from your parts book or the label on the old sensor and you will land on the right item.

Emission-critical parts, tested before packing

A drifting NOx sensor triggers derate, warning lamps and failed inspections. Every sensor in this collection is built to OEM specifications and function-tested before packing — correct connector, correct cable length, correct probe. We supply workshops, fleet maintenance companies and parts distributors in quantity, with neutral packing available for resale. New to NOx sensors?
