12V Nox Sensor 5WK9 6621F 758713005

This 12V NOx sensor, model 758713005, is a critical component for Selective Catalytic Reduction (SCR) systems in modern diesel vehicles. The unit comprises a sensor probe and an electronic control unit connected by a wire harness, designed to measure the concentration of nitrogen oxides and oxygen in the exhaust gas. This data provides the essential feedback for the SCR system to precisely control urea injection, directly reducing harmful NOx emissions. The sensor operates at 12V and is specified for BMW applications, with the probe installed directly in the exhaust pipe where a ceramic element translates gas concentration into a voltage signal for the ECU.

The sensor is supplied as a 100% new, complete unit. Ruian Dellfei Auto Parts states the product carries CE and TS16949 certifications, and offers a one-year quality guarantee with inspection to standard. For SCR system components, typical industry specifications include operating temperature ranges often between -40°C and +1000°C for the probe tip, and response times under 200 milliseconds to ensure accurate real-time emission control. The product comes in neutral packaging, with the option for custom packing arrangements based on buyer requirements.

Automotive parts distributors, diesel engine service workshops, and vehicle fleet maintenance providers are the primary buyers for this sensor. Sourcing from this Zhejiang-based supplier involves confirming the exact wire harness length for your application, which is not specified in the listing. The stated delivery time is 7-15 days, though this should be verified directly with the supplier for your specific order volume and destination. Buyers should also confirm the exact BMW model compatibility for the 758713005 part number and clarify the terms of the one-year quality guarantee before placing a bulk order.
