What wire harness design resources do you provide for engineers?

We provide a comprehensive suite of engineering tools, including AWG to mm² conversion charts, IP protection rating guides, connector cross-reference matrices, and Design for Manufacturability (DFM) checklists to help you optimize your custom cable assemblies.

Can you help me select the right wire gauge and materials for my project?

Absolutely. Our engineering guides offer detailed information on calculating voltage drop, selecting the correct insulation (like XLPE, PTFE, or PVC) for specific temperature ranges, and choosing the right shielding for EMI/RFI protection.

How can I ensure my custom cable assembly design is ready for manufacturing?

We highly recommend reviewing our DFM (Design for Manufacturability) guidelines before finalizing your drawings. Alternatively, you can submit your draft designs to our engineering team for a free feasibility review to eliminate costly errors and reduce lead times.

Frequently Asked Questions

Our resources cover drawing and BOM preparation, connector identification, pinout tables, dimensions, routing, shielding, inspection requirements and quotation planning. Each guide identifies the information needed for a controlled custom assembly specification.

Send the specified wire and component references, operating conditions and equipment requirements. Materials are reviewed against the approved design; electrical and environmental limits should come from the selected component documentation and agreed acceptance criteria.

Prepare a controlled drawing, BOM, connection map, dimensions and inspection requirements. Submit them with sample and production quantities so the assembly scope and any missing information can be reviewed before quotation.
