Micro Coaxial Cable-Micro Coaxial Cable factory-(FRS)-FRS
In industries ranging from automotive electronics to aerospace and smart home installations, the demand for coaxial cables that perform reliably in narrow spaces has grown exponentially. Traditional coaxial cables, however, often struggle with limited flexibility: their rigid insulation layers and thick shielding can lead to excessive signal attenuation when bent, frequent material fatigue, and even permanent damage—critical flaws in environments where wiring must fit into tight gaps (e.g., between automotive dashboard components, inside compact aerospace modules, or within smart home wall cavities). To address these challenges, recent advancements in material science and structural design have significantly enhanced coaxial cable bending performance, making them viable for the most constrained applications.
The breakthroughs focus on two core areas: material innovation and structural optimization, both engineered to balance flexibility with signal integrity and durability.
Traditional coaxial cables rely on rigid dielectric materials (e.g., standard PTFE) that resist bending and degrade signal quality when folded. The improved design replaces these with modified low-dielectric-loss polymers—such as enhanced PFA (perfluoroalkoxy alkane) or thermoplastic elastomers (TPEs) infused with ceramic microfillers. These materials maintain a stable dielectric constant (εr < 2.1) even after repeated bending, reducing signal attenuation by up to 20% compared to traditional cables. For example, in a 10,000-cycle bending test (180° bends at 30 cycles per minute), the improved insulation retained 98% of its original dielectric strength, while standard PTFE insulation showed a 15% drop.
Shielding is another bottleneck for bending performance: thick braided copper shields in traditional cables add rigidity and weight. The optimized design uses tinned copper micro-braid (wire diameter reduced to 0.05mm) combined with a thin aluminum foil layer. This dual-shield structure cuts weight by 15% while maintaining 99.9% electromagnetic interference (EMI) shielding—critical for sensitive electronics like automotive ADAS sensors or aerospace communication modules.
A key metric for narrow-space usability is the minimum bending radius (MBR), the smallest curve a cable can withstand without damage. Traditional coaxial cables typically have an MBR of 8–10 times the cable diameter (e.g., 8mm for an 8mm-diameter cable). The improved design, with its flexible materials and streamlined structure, reduces the MBR to 5–6 times the diameter. For a 6mm-diameter cable (common in smart home devices), this means it can bend to a 30mm radius—small enough to fit inside wall studs or behind compact smart locks.
These improvements solve tangible problems across industries:
To ensure real-world performance, the improved coaxial cables undergo rigorous testing per IEC 61196-1 (the international standard for coaxial cables):
For engineers, installers, and manufacturers, the improved bending performance translates to three critical benefits:
