Import Auto Fakra Antanna Adapter Cable — Buy in wholesale FOB from Supplier in China

The Auto Fakra Antanna Adapter Cable is a RF coaxial assembly built around FAKRA SMB connectors, designed to deliver reliable signal transmission up to 4 GHz at a characteristic impedance of 50 Ω. This cable uses a brass inner conductor with gold plating, a PTFE insulating medium, and a nickel-plated outer conductor to ensure consistent electrical performance across a temperature range of -45°C to +85°C. The RG174 coaxial cable within the assembly features a bare copper inner conductor (7/0.16±0.003 mm), a PE dielectric (1.52±0.05 mm), a bare copper braided outer conductor (80×0.10 mm), and a PVC jacket (2±0.10 mm).

Mechanically, the assembly meets stringent standards with a VSWR of ≤1.3 (DC-4 GHz) and insertion loss of ≤-15 dB across the same frequency range. The connectors are rated for a minimum of 500 mating cycles at 12 cycles per minute, with contact resistance of ≤6 mΩ for the inner conductor and ≤1 mΩ for the outer contact. The cable supports a minimum bend radius of 30 mm and a maximum voltage of 1500 VMS, with insulation resistance of 1000 MΩ. Industry-standard FAKRA connectors use color-coded plastic housings for easy identification, a feature that reduces mating errors in automotive applications.

This adapter cable is primarily used in automotive RF systems where space and reliability are critical, such as GPS, telematics, and infotainment modules. Automotive OEMs and aftermarket suppliers source these assemblies for their compact design, resistance to vibration, and consistent performance in harsh environments. Buyers typically confirm compatibility with their vehicle’s connector coding and cable length requirements before ordering, as FAKRA standards include multiple keying options to prevent mismating.

Shenzhen Sihanming Technology Co., Ltd. operates from Fuyong, Shenzhen, in Guangdong Province, China. The company specialises in RF connectors and cable assemblies, with a focus on automotive and industrial applications where signal integrity and durability are critical. Its product line includes FAKRA connectors, a standard in automotive RF systems, alongside custom cable solutions tailored to client specifications.

The supplier is classified as an imported tier with a harbor trust tier, indicating a verified presence in international trade directories. While the response rate and average response time are currently unrecorded, the technical depth of its product descriptions suggests a focus on engineering precision. The company’s listings provide detailed electrical and mechanical specifications, which is a strong indicator of its commitment to transparency in B2B transactions.
