Frequently asked questions
What is a wire harness?
A wire harness is an assembly of insulated conductors, connectors, terminals, and protective materials, designed to transmit electrical signals or power between components.
What is a cable assembly?
A cable assembly is a structured group of conductors, often with shielding, insulation, and external armor, engineered for specific environmental and mechanical conditions.
How do I choose a connector?
Consider current rating, voltage, mating cycles, environmental exposure, tooling requirements, and compatibility with your harness design. Match the connector to the application, not to cost alone.
What are common wire harness failure modes?
Typical failures include insulation breakdown, connector corrosion, terminal loosening, chafing, and moisture ingress. These often stem from poor design, material mismatch, or assembly defects.
Why is testing important?
Testing verifies insulation resistance, continuity, and mechanical integrity. It catches defects before the harness reaches production, reducing field failures and rework.
How do I evaluate a harness supplier?
Review their quality systems, testing capabilities, material sourcing, lead time reliability, and past performance. Ask for sample builds and inspection reports to confirm capability.
