An Introduction to Sensor King NOx Sensors

A NOx sensor (Nitrogen Oxide sensor) is a crucial component in modern vehicles' emission control systems. It measures the levels of nitrogen oxides (NOx) in the exhaust gases to ensure they are within permissible limits. By providing this data to the engine control unit (ECU), the sensor helps optimize the air-fuel mixture and enhance the performance of the catalytic converter, reducing harmful emissions and improving fuel efficiency.

At Sensor King, we provide high-quality NOx sensors for both passenger and commercial vehicles. Our sensors meet Euro 6 standards and OEM requirements, including hardware specifications like bracket parameters, and are pre-programmed with the OEM protocol for easy installation .

They feature advanced PCB design with optimized alignment and multi-layer construction for improved EMC performance, signal stability, and accuracy. The high-performance MCU operates at 80MHz with various co-processing units and ample Flash storage, while the ASIC chip ensures precise current referencing and supports multiple communication protocols for enhanced control and reliability. Additionally, our IC devices meet the AEC-Q100 standard, passive devices meet the AEC-Q200 standard, and our product design complies with EMC testing requirements according to automotive company standards such as Bosch.

When it comes to aftermarket NOx sensors, one of the most significant engineering challenges is matching the OEM protocol. OE manufacturers may occasionally change protocols, even within the same model year. To ensure your satisfaction, we will BUY your faulty OEM sensor if our sensor is found to have software issues. You can purchase our NOx sensor with zero worries.
