This is the reference brief: the terminology, standards landscape and buyer questions that come up in every harness conversation — compiled so you can navigate the deeper guides without re-reading the whole library.
Essential Terminology
- Harness vs cable assembly: harnesses bundle multiple wires with routing/protection as a machine part; cable assemblies are finished cables connector-to-connector (the boundary blurs in practice — both are 'wire harnesses' commercially).
- AWG: American Wire Gauge — smaller number, bigger wire (our battery cable guide maps gauges to current).
- UL style numbers: the AWM system's wire specifications (our UL guide explains).
- Crimp: the compressed metal joint between wire and terminal — the industry's core termination (our crimp guide covers the discipline).
- IP rating: ingress protection (IP67 = dust-tight + 1m/30min immersion — our test guide covers verification).
- Build-to-print: manufacturing exactly to the customer's drawing (our CP guide shows the workflow).
- DFM: design for manufacturability — design choices that make a harness producible repeatably (our DFM guide details).
Standards Landscape
The frameworks buyers encounter: UL/CSA for component and wire styles (North American compliance), IPC/WHMA-A-620 for harness workmanship acceptance (the industry's workmanship bible — our IPC guide covers it), IATF 16949 for automotive quality systems, ISO 13485 for medical devices, RoHS/REACH for material compliance. Program requirements reference these frameworks — the supplier's certifications answer the first layer of procurement diligence.
Questions Buyers Actually Ask
- How do I get a quote? With engineering data: schematic, drawing (or at minimum wire list + connector part numbers), environment description, quantities and target markets. Our processing guide shows what production needs to see.
- Prototype to production — same supplier? Yes, and the transition discipline (documentation, process lock) is what separates serious manufacturers from shops that build prototypes only.
- What's the minimum viable spec? A wire list (from-to, gauge, length), connector part numbers, and the application description — a manufacturer like Kaweei engineers the rest into a drawing for approval.
- How is quality verified? 100% electrical test as the baseline, plus the class-specific additions (hipot, pull tests, leak tests — our testing guide details).
- Why do harness quotes vary so much? Material classes (wire insulation, connector sources, protection), process rigor (calibration, testing depth), and compliance scope — the quote reads the program.
Where to Go Deeper
The library's structure: application guides (automotive, medical, industrial, energy), technology guides (connectors, waterproofing, EMC, shielding), component guides (specific connector families and cable types), and process guides (crimping, testing, DFM). Each covers its domain in depth — this brief is the map.
