I-PEX 82893-100B-02-D 26P High-Speed Signal Transmission Super-Thin Coaxial Cable Replacement

High-speed connection for slim and lightweight electronic devices requires ultra-fine coaxial cable bundles as a key connection solution.

With the continuous trend towards thinning and miniaturization of laptops, tablets, smart wearable devices, VR/AR devices, and high-performance camera modules, the internal space of the devices is constantly compressed. The traditional cable scheme has become increasingly difficult to meet multiple demands such as space occupation, signal transmission, flexible bending, and EMI anti-interference performance. Against this backdrop, the ultra-thin coaxial cable harness (Micro Coaxial Cable Harness) has gradually become an important solution for internal connections in high-density electronic devices due to its small outer diameter, high shielding performance, high-speed signal transmission capability, and excellent flexibility.

The ultra-fine coaxial cable achieves stable data transmission capability within a limited space through a highly miniaturized design of the central conductor, insulation layer, shielding layer, and outer sheath structure. Compared with traditional FFC/FPC connection methods, the ultra-fine coaxial cable not only supports higher frequency signal transmission but also has better electromagnetic interference resistance. It is particularly suitable for internal connections of electronic products that require display modules, camera modules, high-speed data interfaces, and connections that need to pass through pivot points or narrow spaces.

For example, the I-PEX CABLINE®-UA II series solution adopts a 0.3mm pitch ultra-fine spacing connection structure, supporting 26Pin, 32Pin, 40Pin, and 50Pin specifications, and supporting ultra-fine coaxial applications with AWG42, AWG44, and AWG46 Micro Coax. The 26Pin solution can achieve a compact layout through a miniaturized Plug structure, meeting the design requirements for internal space in thin and light electronic devices.

This type of cable assembly can be applied to laptop display connections, camera modules, high-speed image equipment, and other electronic products that require high-density signal transmission.

How ultra-fine coaxial cables meet the demand for thin and light electronic devices? Engineering design advantages analysis

One of the biggest challenges for electronic device structural engineers in thin and light design is how to complete more high-speed signal connections within increasingly smaller internal spaces. Extremely fine coaxial cable bundles are a high-density connection technology that has developed in response to this need.

Firstly, extremely fine coaxial cables have very small outer diameter dimensions, which can effectively reduce the space occupied by cable bundles inside the equipment. For example, in the CABLINE-UA II series solutions, after using ultra-fine Micro Coax cable material, the cables can adapt to narrow space layouts and support wiring design in the rotation axis area, providing greater structural design freedom for foldable devices, ultra-thin notebooks, and other products. Official data shows that the 26Pin CABLINE-UA II cable bundles made with coaxial cables of about 0.29mm outer diameter can pass through a Φ2.65mm inner diameter space to realize internal wiring in the rotation axis structure.

Secondly, ultra-fine coaxial cables use coaxial shielding structures, where each signal line has independent shielding capability, which can effectively reduce crosstalk and electromagnetic interference generated during high-speed signal transmission. For current high-speed display interfaces, camera data transmission, and high-speed image applications, this structure can improve signal integrity and reduce signal quality degradation caused by space compression.

In addition, extremely fine coaxial cable bundles have good flexibility and can adapt to complex routing paths inside equipment. Compared with traditional rigid connection schemes, Micro Coax cable bundles can more easily meet the reliable connection needs in rotational axis movement, folding structures, and dynamic bending environments.

Therefore, for electronic device manufacturers pursuing thinness, high performance, and high reliability, extremely thin coaxial cable束 has become an important connection technology for product structural innovation.

Four, selection and compatibility and alternative solutions reference and suggestions

When selecting ultra-fine coaxial cable assemblies, engineers and purchasing personnel usually need to pay close attention to key parameters such as connector platform, pin count, Micro Coax cable specifications, cable length, impedance requirements, and the structural design of both ends.

For the I-PEX CABLINE-UA II series products, our company recommends that customers pay close attention to the following matching conditions during the replacement development process:

First, connector specification matching.

The original scheme adopts the CABLINE-UA II series 26Pin connection structure, corresponding to the wire end connector model: 20497-026T-30.

When replacing development, it is necessary to ensure that the connector pin count remains consistent and meets the 0.3MM pitch specification requirements.

Second, wire specification matching.

I-PEX 82893-100B-02-D uses: 44AWG Micro Coax ultra-fine coaxial cable

As the core transmission medium, alternative solutions need to be designed to match the requirements of customer high-speed signals, including wire diameter, impedance, attenuation performance, and shielding performance.

Third, structural dimension matching.

Including the wire harness length of 100mm, cable exit direction, terminal molding method, tape fixing method, and assembly space dimensions, all need to be confirmed according to the structure of the terminal product.

Fourth, high-speed signal performance verification.

For display, camera, and high-speed data transmission applications, it is necessary to focus on the evaluation of signal integrity indicators such as insertion loss, return loss, crosstalk, and differential impedance.

As electronic devices continue to develop towards slimming down and becoming more powerful, ultra-fine coaxial cables have become an important basic component for connecting display, camera, and high-speed data transmission modules. The I-PEX 82893-100B-02-D, as a 26Pin, 44AWG Micro Coax solution in the CABLINE-UA II series, represents the current development direction of high-density electronic connections with its 0.3MM pitch connection structure, miniaturized design, and high-speed signal transmission capability.
