The Diesel NOx sensor 5WK9 6766A SNA166A is a direct replacement for Cummins ISX and QSX engine platforms, designed to measure nitrogen oxide concentrations in exhaust streams for SCR system feedback. It features a ceramic sensing element enclosed in a stainless steel housing, operating at 24V DC with a response time under 200 milliseconds. The sensor outputs a voltage signal proportional to NOx levels, enabling precise urea injection control to meet Euro VI and EPA 2010 emission standards.
This sensor uses a zirconia-based ceramic chip with platinum electrodes, a standard design in heavy-duty diesel aftertreatment systems. The housing is rated for continuous exposure to exhaust temperatures up to 850°C and resists sulfur and soot deposition. While the listing states CE and ISO/TS 16949 certification, buyers should verify the certificate validity directly with the supplier, as these are common industry benchmarks but not guaranteed for every batch without third-party audit documentation.
The sensor is used primarily by fleet maintenance providers, diesel engine rebuilders, and aftermarket distributors serving North American, European, and Southeast Asian trucking markets. It is packed in neutral, anti-static blister packs with foam inserts, and custom labeling is available upon request. Delivery typically takes 7 to 15 days from Wenzhou port, with FOB or CIF terms negotiable. Buyers should confirm compatibility with their specific Cummins ECU software version before ordering.

Ruian Dellfei Auto Parts Co.,Ltd is based in Ruian, Zhejiang Province, China, operating from Building 33, Section B, Zhihui Industrial Park. The company specializes in emission control components for commercial diesel engines, with a focus on NOx sensors and EGR valves. The listing confirms a harbor-tier trust rating and a verified business address, but no company history, employee count, or export volume is provided. Response metrics show no recorded activity, suggesting limited customer interaction or a dormant sales channel.
The supplier does not claim certifications, production capacity, or client names. It is not listed as a Cummins OEM partner or authorized distributor. Buyers should treat this as an independent aftermarket supplier. The product is manufactured to meet industry standards, but without independent lab test reports or batch traceability, quality assurance relies on post-delivery verification. The company’s operational scope appears limited to export fulfillment without public-facing technical support or warranty administration.
This CUMMINS diesel NOx sensor 5WK9 6766A is an essential emission monitoring component for heavy-duty diesel engines in trucks and power generation units. The sensor probe installs directly in the vehicle exhaust system and uses advanced ceramic chip technology to measure nitrogen oxide concentration levels for SCR emission compliance. Ideal for CUMMINS ISX and QSX engine platforms, this sensor supports clean air regulation compliance and is a critical replacement part in the global diesel aftertreatment market.

Before placing an order, verify the sensor’s compatibility with your Cummins engine model and ECU software version. Request a copy of the calibration curve and confirm the sensor is not a reconditioned unit. Ensure the product code matches SNA166A exactly, as similar-looking sensors may have different voltage outputs or pin configurations. Confirm the packaging is anti-static and sealed to prevent moisture damage during transit.
Lead time is typically 7 to 15 days from Wenzhou, but confirm whether this includes customs clearance. Negotiate FOB Wenzhou or CIF destination port terms, and clarify who bears responsibility for import duties. Payment terms are not stated; request a proforma invoice with clear Incoterms, bank details, and a payment schedule tied to production milestones. Avoid advance payments without a written contract.
Upon receipt, inspect the sensor for physical damage, verify the batch number matches the packaging, and test the voltage output with a multimeter under simulated conditions. Request a certificate of conformity and test report for NOx sensitivity and response time. Retain packaging for 90 days in case of warranty claims. For fleet operators, sample test a batch of five units before full delivery to validate consistency.
