High-speed interconnect solutions in automated equipment: Analysis of extremely thin coaxial cable束

In today's era of continuous upgrading of automated equipment, high-speed signal transmission not only affects the efficiency of system operation but also directly relates to the stability and accuracy of the equipment. In order to achieve high-speed, reliable, and low-noise data transmission within limited space, extremely thin coaxial cable束 (micro coaxial cable) has become an important interconnection solution in automated systems, thanks to its excellent shielding capability, impedance control, and flexible structure.

I. The structural characteristics and technical advantages of extremely fine coaxial cable bundles

The extremely thin coaxial cable bundle consists of a central conductor, insulation layer, shielding layer, and sheath. Compared to ordinary wires, it is more suitable for high-speed transmission in compact spaces. Its commonly used impedance is 50Ω or 45Ω, which can support high-speed differential or single-ended signals, meeting GHz-level data link requirements. Owing to the coaxial structure, it can reduce external electromagnetic interference, maintain signal integrity, and still has high stability and low error rate performance in high-speed transmission scenarios.

Typical application scenarios in automated equipment

In precision robots, industrial sensors, and vision detection systems, space is compact and there is a high demand for real-time performance and stability. Extremely fine coaxial cables can ensure reliable signal transmission. For automated equipment using USB, HDMI, and high-speed data buses, micro-coax effectively improves signal fidelity and avoids data distortion. In equipment such as automated medical devices and optical detection, its small size and strong shielding characteristics are more suitable for placement inside complex structures, enabling stable transmission of high-frequency signals.

Three, Key Challenges in the Production Assembly and Selection Process

Extremely thin coaxial cable bundles can have a wire diameter as fine as 50AWG, which may result in insufficient connector height of less than 1.2mm, making manual processing extremely difficult. Therefore, automated processing has become the main method, including automatic cutting, precise stripping, coaxial processing, and visual inspection, etc., with stripping accuracy that can be controlled within ±50 micrometers, significantly improving consistency and quality. At the same time, when selecting, it is necessary to pay close attention to signal integrity, impedance matching, connector compatibility, mechanical bending performance, assembly method, and environmental adaptability to obtain better system reliability.

In modern automation systems, ultra-fine coaxial cable bundles have become one of the core components of high-speed and high-precision equipment. With their excellent shielding capability, impedance control, flexible structure, and advantages of automated processing, they can maintain long-term stable operation in complex environments. Scientific selection and professional assembly will directly enhance the performance and reliability of the equipment.
