At Cornelius Electronics, manufacturing expertise is ingrained in our DNA, and our commitment to excellence is evident in every stage of the wiring harness building process. Firstly, clearly define the purpose of your wiring harness design. Delve into specific needs such as vibration resistance and environmental conditions to tailor the harness to your unique requirements. Moving forward, meticulous attention to specifications is crucial. Carefully choose wires and components based on electrical demands, environmental considerations, and mechanical properties.

Connectivity is a critical aspect. Select connectors that align with wire properties, accounting for circuit size, ease of joining, and insulation. Next, focus on routing. Plan wire routes strategically for accessibility, minimise electromagnetic interference risks, and segregate wires by function and voltage.

To safeguard against mechanical stress, incorporate strain-relief components and select appropriate materials. Leverage wiring harness design tools to generate accurate schematics, identifying potential issues and ensuring repeatable, controlled quality. Apply protective coverings based on environmental conditions and material properties.

Quality testing should be seamlessly integrated into the design process to assess electrical integrity, resistance, and connections. Comprehensive documentation, including schematic design and connector information, is vital for after-sales and service.

Finally, ensure compliance with regulatory and safety standards, tailoring your wire harness design to meet the specific requirements of your region or international markets. For an unparalleled level of expertise, trust Cornelius Electronics to harness the power needed for your project. Our skilled professionals are dedicated to delivering excellence in every wiring harness we build, making us the ideal partner for your next endeavour.
