Product details

With standardized production lines and rigorous quality management, we support clients from technical drawing evaluation through prototype testing to volume production. We supply a comprehensive range of automotive cable and connectors tailored to heavy-duty truck SCR systems, exhaust temperature monitoring and urea aftertreatment modules. Our engineering team develops various custom wiring harness for sensor signal transmission, control unit interconnection and industrial electronic systems. We also produce professional automotive diagnostic cables and matching adapters that work with mainstream vehicle diagnostic platforms. All products follow RoHS material requirements and undergo full electrical inspection before shipment.

Custom HDB26 Male to 3 Way Exhaust Temperature Sensor Wiring Harness

This HDB26 male to 3 way exhaust temperature sensor wiring harness is a dedicated signal interconnection assembly designed for commercial vehicle exhaust temperature monitoring systems. Different from multi-branch urea level sensor harnesses and ordinary extension cables, this product focuses on a streamlined three-branch architecture: one HDB26 26Pin main connector splits into three independent 4Pin square sensor connectors, covering Cummins 2-wire exhaust temperature sensor, Cummins 4-wire exhaust temperature sensor and Bosch exhaust temperature plus urea sensor configurations. This targeted design allows the vehicle control unit to simultaneously collect temperature data from multiple exhaust positions, supporting precise SCR system regulation and emission compliance management. A built-in PCB board organizes the internal pin mapping, keeping signal paths stable and well-protected against cross-talk between different sensor circuits.

Each branch adopts UL2464 certified 22AWG 4-core shielded cable with black semi-matte PVC outer jacket, integrating aluminum foil shielding layer to suppress electromagnetic interference from the high-temperature engine bay and exhaust system. The cable is engineered to operate reliably within -40℃ to +80℃ ambient temperature range, adapting to the harsh thermal environment near commercial vehicle exhaust pipes and chassis. The three branch connectors feature blue overmolded housings with color-coded internal inserts for quick visual identification during installation and maintenance. Clear identification labels are pre-attached on each branch cable, allowing technicians to distinguish between different sensor circuits without tracing wires back to the main connector.

Every finished harness undergoes strict 100% electrical testing before delivery, including full continuity inspection, DC 300V withstand voltage test, insulation resistance measurement and conduction resistance verification to eliminate open circuits, short circuits and pin misalignment. The insulation resistance is maintained above 10MΩ while maximum conduction resistance is controlled within 2Ω, ensuring accurate and stable temperature signal transmission under continuous working conditions. All raw materials fully comply with RoHS environmental requirements. The connector housings are made of high-strength PA66+GF engineering plastic, featuring excellent mechanical strength, vibration resistance and sealing performance. Heat shrink tubes are applied at cable-to-connector transition positions for reinforced strain relief, preventing wire breakage caused by long-term vehicle vibration and thermal cycling.

This exhaust temperature sensor harness is widely applied in heavy-duty truck SCR systems, Cummins exhaust temperature sensor connection, Bosch urea and temperature sensor integration, commercial vehicle emission control modules, diesel engine aftertreatment management and vehicle sensor signal acquisition projects. It serves as a dependable signal transmission medium between the vehicle electronic control unit and multiple exhaust temperature sensors. If your project requires different branch counts, connector styles, cable lengths or custom pin assignment, our team can adjust the design to create a dedicated custom wiring harness for your application. We continuously refine the high-temperature resistance and signal accuracy of every product in our automotive cable and connectors lineup to meet demanding commercial vehicle requirements. Our automotive diagnostic cables can also be paired with these sensor harnesses to support complete vehicle diagnostic and emission testing workflows. Welcome to send technical drawings or sample requests for detailed evaluation and competitive quotation.
