I-PEX CABLINE-UY series and 81426-100B-03-D product introductionAs smart terminals, display devices, industrial electronics, and high-performance computing equipment continue to develop towards thinness and high integration, the internal connection space of the devices is gradually shrinking, and higher requirements are placed on the miniaturization of connectors and cable harness components, as well as on their high-speed signal transmission capabilities and stability. The CABLINE®-UY series launched by I-PEX is a micro-coaxial connection solution specially designed for ultra-thin electronic devices. With advantages such as low height, small spacing, and high-speed transmission, it is widely used in internal connection scenarios of space-limited devices. Among them, the I-PEX 81426-100B-03-D is a product model of the CABLINE-UY series 5Pin Micro-Coaxial Harness (micro coaxial harness component), which can meet the needs for high-density, high-reliability signal connections.
According to the official information of I-PEX, the 81426-100B-03-D uses the CABLINE-UY series connection structure, which belongs to a 5-core miniature coaxial cable assembly. It is designed with Micro-Coaxial Cable (miniature coaxial cable) and has excellent signal integrity and electromagnetic interference resistance. The product has a compact overall structure, suitable for installation in laptops, display modules, industrial equipment, high-speed imaging equipment, and other precision electronic products. It can help equipment manufacturers optimize internal space and improve product connection stability.

Product characteristics and application advantages of 81426-100B-03-DThe core strengths of I-PEX 81426-100B-03-D lie in miniaturization, high density, and high-speed signal transmission capabilities. Compared with traditional multi-core cable harness solutions, the miniature coaxial cable harness structure can effectively reduce signal attenuation and minimize the impact of external electromagnetic interference on high-speed signals, enabling devices to maintain stable data transmission performance under complex operating environments. At the same time, the prefabricated Harness cable harness design can simplify the assembly process of devices, improve production efficiency, and ensure product consistency.
The CABLINE-UY series products adopt ultra-thin connection design, which can meet the dual needs of space saving and performance improvement for modern electronic devices. This model is suitable for applications such as display connections, high-speed camera modules, industrial vision systems, and internal signal transmission in smart devices, especially for application scenarios with high requirements for installation space, connection reliability, and signal quality.

Selection, compatibility, and alternative solutions reference and recommendationsWhen selecting or designing alternatives for the I-PEX 81426-100B-03-D, it is necessary to pay close attention to parameters such as connector series matching, pin count, cable length, cable specifications, terminal definition, installation direction, and electrical performance. Since micro coaxial cables are precision connector components, alternative solutions not only need to achieve mechanical size compatibility but also ensure high-speed signal transmission performance and long-term use reliability.
