I-PEX 82444-100B-02-D 50P high-speed signal transmission extremely thin coaxial cable replacement

Solution for 50PIN ultra-thin coaxial cable束 for high-speed signal transmission requirements

With the continuous development of laptops, AI devices, high-speed camera modules, industrial vision equipment, and ultra-thin display devices towards thinness and high speed, higher requirements have been put forward for the internal connection cables of the devices. Traditional FPC or ordinary ribbon cables are prone to be affected by electromagnetic interference, signal crosstalk, and spatial limitations during the high-speed signal transmission process. The ultra-fine coaxial cable, with its independent shielding, high impedance control, and excellent high-speed transmission performance, has become an important choice for internal connection solutions in an increasing number of high-end electronic devices.

This article introduces the I-PEX 82444-100B-02-D compatible alternative ultra-thin coaxial cable assembly solution, which corresponds to the I-PEX CABLINE®-SS series 50Pin ultra-thin coaxial cable assembly. According to product information, this specification adopts a high-density connection structure with 50PIN and 0.4mm pitch (terminal spacing), paired with the CABLINE®-SS series cable end connector 20373-R50T-06, suitable for internal connections of electronic devices that are compact in space and require stable high-speed signal transmission.

For engineers, this type of harness not only needs to meet the connection size requirements, but also pay attention to high-speed signal integrity, impedance matching, attenuation performance, and long-term reliability; for purchasers, it is necessary to focus on supply stability, specification compatibility, and the ability to replace domestic products.

Our company specializes in the research and development and manufacturing of extremely thin coaxial cable assemblies, and can provide a compatible and alternative cable solution for I-PEX 82444-100B-02-D based on customer equipment requirements, helping customers achieve domestic substitution with high performance and high reliability.

Second, ultra-fine coaxial beam structure design and high-speed transmission performance analysis

The I-PEX CABLINE®-SS series is a miniature coaxial connector system developed for high-speed electronic devices, featuring a 0.4mm ultra-fine pitch design, high-speed transmission capability, and miniaturized structural characteristics. This series of connectors supports Micro-Coaxial Cable (extremely fine coaxial cable) and is applicable to wire materials of specifications such as AWG40. I-PEX CABLINE-SS series chat records

This scheme corresponds to the I-PEX 82444-100B-02-D ultra-fine coaxial cable assembly, using:

• Product Model: I-PEX 82444-100B-02-D

• Connector Model: 20373-R50T-06

50PIN

• Connector spacing: 0.4MM Pitch

Extremely thin coaxial specifications: AWG40

AWG40 ultra-fine coaxial cables have a smaller outer diameter and better spatial adaptability compared to ordinary cables. According to the I-PEX CABLINE®-SS specifications, AWG40 Micro-Coaxial Cable is typically used in high-speed signal transmission testing environments and can achieve a 45Ω impedance matching design.

In the process of high-speed signal transmission, engineers usually focus on the question of "What is the typical attenuation rate of ultra-thin coaxial cables?"

In fact, the attenuation rate of ultra-fine coaxial cables is not a fixed value but is affected by wire diameter, frequency, impedance, material structure, and cable length. Generally, under 10MHz test conditions, the attenuation index of AWG40 level miniature coaxial cables is about 0.45dB/m (differences may exist in different manufacturers, structures, and materials).

As the signal frequency increases, for example, in scenarios such as high-speed displays, USB, and high-speed cameras, attenuation increases with frequency, so in actual projects, it is necessary to combine:

Work frequency

Transmission Distance

Impedance requirements

  Connector performance

•  Blocking structure

Conduct a comprehensive assessment. Miniature coaxial cable

Therefore, when developing alternative harnesses, it is not only necessary to focus on the appearance and size match, but also more importantly, to conduct high-speed signal test verification, including insertion loss, return loss, and crosstalk performance analysis.

Three, focus points of engineering selection: shielding performance, reliable connection and alternative development solutions

For high-speed equipment manufacturers, when selecting ultra-fine coaxial cables, attention should be paid to connector matching, cable specifications, and overall signal performance.

The I-PEX CABLINE®-SS series adopts the W-Point dual-contact point contact structure, which can improve the terminal contact stability and reduce the risk of contact abnormalities caused by dust, vibration, and long-term use.

At the same time, ultra-fine coaxial cables adopt a structure with a central conductor, insulation layer, and an external shielding layer. Each signal line has independent shielding capability, which can effectively reduce:

Signal crosstalk between lines

External electromagnetic interference impact;

Signal attenuation during high-speed transmission.

For engineering selection and procurement alternatives, the following plan can be referred to:

Selection, compatibility, and alternative solutions reference and suggestions

For customers in need of replacement I-PEX factory cables, it is recommended to prioritize the confirmation of the following:

Firstly, it is necessary to confirm that the connector specifications are consistent, including:

Connector series;

PIN quantity

  Pitch spacing;

  Insertion and extraction direction

• Outlining direction.

This product uses the 20373-R50T-06 cable end connector, 50PIN, 0.4MM Pitch, which can be used as a reference for the CABLINE®-SS 50PIN series applications.

Secondly, it is necessary to confirm the specifications of the ultra-fine coaxial cable.

This scheme adopts a 40 AWG ultra-fine coaxial cable, suitable for high-speed signal transmission requirements. In the actual development process, appropriate wire diameter should be selected according to the device signal rate, length, and spatial constraints.

Finally, it is necessary to carry out the whole harness verification:

Including size compatibility testing, connection reliability testing, high and low temperature environment testing, and high-speed signal integrity testing.
