Cable Assembly
FAKRA programs fail when buyers approve only the connector code and cable length. We review color coding, impedance, mating interface, sealing level, route packaging, and test scope before quote so your approved build survives DV, vehicle installation, and recurring production.
Application Context
FAKRA is the standardized automotive RF connector interface built on a coaxial cable architecture, using color coding and mechanical keying so each antenna, sensor or module link mates only where it should. A FAKRA assembly only performs when the connector code, keying, 50 ohm coax construction, shield continuity, sealing level and route packaging are all correct for the vehicle integration point — not just the connector code and cable length. That is why we review color coding, impedance, mating interface, sealing level, route packaging and test scope before quote, so the approved build survives DV, vehicle installation and recurring production.
The same discipline carries across our other RF and data interconnects — from SMA connector assemblies and Rosenberger connector assemblies to broader shielded cable assemblies — and pairs directly with full-vehicle programs through our automotive and EV wire harness capability.
Capabilities
Built for procurement teams that need automotive-grade RF assemblies, not generic coax jumpers.
We manufacture custom FAKRA cable assemblies for GPS, GNSS, LTE, 5G, AM/FM, satellite radio, camera, and radar-adjacent vehicle programs where connector coding, retention, and electrical stability matter from prototype through SOP.
A FAKRA RFQ is not complete when it only says blue or beige. We review code family, keying, cable type, interface orientation, panel or module fit, and route constraints before quotation so the approved assembly matches the actual vehicle integration point.
FAKRA assemblies are only as stable as the coax architecture behind the connector. We align conductor, dielectric, braid coverage, jacket, and routing assumptions to the target frequency range and installation environment instead of quoting a generic cable that creates field noise or loss.
Automotive FAKRA cables often run through vibration, temperature cycling, moisture, and service handling. We support sealed connector variants, connector-to-cable strain relief, and packaging controls to reduce intermittent faults after installation.
Engineering Challenges
Color code family, keying and mating orientation confirmed against the actual vehicle port so a fast quote does not become the wrong assembly at the integration point.
50 ohm coax construction, conductor, dielectric and braid coverage matched to the target frequency range so radar, camera and antenna links stay stable instead of adding field noise or loss.
IP-rated sealed connector variants, connector-to-cable strain relief and packaging controls chosen for temperature cycling, moisture and vibration to reduce intermittent faults after installation.
Approved BOM, connector coding, work instructions and inspection logic locked after samples, with electrical and RF test scope defined to the right level for prototype, pilot and production.
Technical Capabilities
Build-to-print FAKRA and automotive RF assemblies with documented cable, connector, impedance, sealing and test review before release.
Manufacturing Process
Quality & Testing
Every FAKRA assembly gets continuity, pin-mapping, shield-continuity and connector-retention verification with visual inspection, and programs with tighter RF risk can add insertion-loss, return-loss or other application-specific validation — all documented for revision-controlled traceability before it ships.
Why WHP
We reduce procurement risk before the first sample leaves the line.
We review code family, mating side, cable path, shielding assumptions, and test scope before quote. That prevents the common failure mode where the quote is fast but the assembly is wrong for the vehicle package.
Sample lead time, production lead time, MOQ, and documentation scope are defined early so sourcing teams can compare suppliers on actual program readiness instead of unit price alone.
Once samples are approved, we lock the approved BOM, connector coding, work instructions, and inspection logic so recurring releases do not drift from the validated version.
Not every FAKRA cable needs the same validation scope. We help define the right level of electrical, mechanical, and reporting control for prototype, pilot, and production stages.
Factory review and release checks map to the references buyers use to compare FAKRA cable programs.

Representative Project
Representative project type we handle, shown for illustration. Not a specific named customer.
Scenario: An automotive RFQ for an EV HVAC adapter cable required aggressive cost optimization for a multi-part program.
Challenge: The customer explicitly stated that 'each cent counts' and demanded maximum cost reduction, requiring alternative sub-component sourcing strategies without compromising quality or vehicle standards.
Solution: Proposed a dual-quote strategy featuring the original drawing specifications alongside an alternative sub-component and material optimization plan, leveraging direct partnerships with sub-component manufacturers to cut intermediary costs.
Result: Submitted a compliant and competitive quote with viable cost-saving alternatives, maintaining position in the evaluation for a high-value multi-part program.
