I-PEX 82973-100B-02-D 12P high-speed signal transmission ultra-thin coaxial cable replacement

A ultra-fine coaxial cable assembly solution for high-speed device connection requirements: small space, high speed, and high reliability transmission

With the continuous development of devices such as high-speed image acquisition, AI vision detection, industrial cameras, intelligent terminals, and display modules towards miniaturization and high integration, higher requirements have been put forward for high-speed signal connection cables inside the equipment. Traditional FPC ribbon cables are prone to be affected by factors such as impedance control, signal attenuation, and electromagnetic interference during the transmission of high-speed differential signals, while ultra-thin coaxial cables, with their excellent impedance stability, low signal loss, and good anti-crosstalk capability, have gradually become an important solution in the field of high-speed connections.

This product solution corresponds to the I-PEX CABLINE-UY 12Pin Harness ultra-fine coaxial cable assembly product code: 82973-100B-02-D. The product adopts a 12Pin high-speed connection structure, a Micro-Coaxial Cable (ultra-fine coaxial) design, cable length of 300mm, and 1-N connection method, which can meet the needs of high-speed display, high-speed image acquisition, and internal connections for precision electronic equipment.

The cable end connector model used with this scheme is 20907-012E-01. This connector belongs to the CABLINE-UY series Plug Housing (plug plastic housing) component, which can support ultra-thin coaxial cable specifications of 42AWG, 40AWG. It can match different wire diameter schemes according to different high-speed signal transmission requirements, realizing spatial optimization and signal performance balance.

Why the characteristic impedance of ultra-fine coaxial cable束 needs to be designed as 50Ω? The key analysis of high-speed signal transmission stability

In high-speed image acquisition, high-speed data communication, and display transmission applications, extremely thin coaxial cables not only need to meet size requirements but also need to ensure high-speed signal integrity. Among them, impedance control is a key factor affecting the quality of high-speed signal transmission, and 50Ω impedance design is one of the most common engineering choices for the application of extremely thin coaxial cables.

Why are extremely thin coaxial cable bundles usually designed as 50Ω?

High-speed signals propagate in extremely thin coaxial cable bundles in the form of electromagnetic waves between the conductor and the shielding layer. When the characteristic impedance of the cable bundle does not match the system interface impedance, signal reflections occur, leading to distorted signal waveforms, degraded eye diagrams, and increased data error rates. The 50Ω impedance achieves a good balance between signal attenuation, power transmission capability, and electromagnetic performance, and is therefore widely used in high-speed communication, radio frequency, and high-speed differential signal connection fields.

For high-speed Micro-Coaxial Cable solutions like the 82973-100B-02-D ultra-fine coaxial cable束, precise control over conductor diameter, insulating layer thickness, shielding layer structure, and outer diameter dimensions can achieve stable impedance control, ensuring that high-speed signals maintain good integrity in long-distance, small-space wiring environments.

Especially in applications such as high-speed cameras, machine vision, and AI detection equipment, the amount of image data is continuously increasing, and the interface data rate is also increasing. The extremely thin coaxial cable束 not only needs to meet the mechanical connection requirements but also needs to have stable electrical performance. A reasonable 50Ω impedance design can help engineers reduce the risk of high-speed signal transmission and improve the reliability of the whole machine.

Three, 82973-100B-02-D ultra-fine coaxial cable assembly selection, compatibility, and alternative solution reference and suggestions

For engineers and procurement personnel, when selecting high-speed ultra-fine coaxial cable assemblies, they need to focus on connector compatibility, cable specifications, Pin quantity, cable length, and high-speed signal performance matching.

For the alternative application of I-PEX CABLINE-UY 12Pin Harness 82973-100B-02-D, it is recommended to focus on the following aspects:

Firstly, it is necessary to confirm the connector matching relationship. The wire harness used in this type of line uses the wire end connector model 20907-012E-01, which belongs to the 12Pin CABLINE-UY series connector structure. During the alternative development, it is necessary to ensure that the connector外形尺寸, Pin definition, assembly method, and PCB end matching relationship are consistent.

Next, it is necessary to confirm the specifications of ultra-fine coaxial cables. This connector supports ultra-fine coaxial cables with 42AWG and 40AWG, and different AWG specifications will affect the flexibility of the harness, transmission loss, current carrying capacity, and overall structural design. For example, 42AWG cables have a smaller diameter and are more suitable for space-limited and miniaturized devices; 40AWG cables are relatively thicker and have advantages in some high-speed transmission and applications with high requirements for mechanical reliability.

At the same time, it is also necessary to verify with practical applications.

• Signal type (high-speed differential signal, display signal, image signal, etc.)

Transmission rate requirement

Impedance requirement

Cable length

Bend radius

Work environment temperature

By matching the above parameters, it can be ensured that the substitute harness meets the original product's application requirements in terms of mechanics, electricity, and reliability.
