For engineers and purchasers, "ultra-fine coaxial cable assemblies" and "traditional coaxial cables" are both coaxial transmission solutions, but their design focuses are not entirely the same. Traditional coaxial cables usually emphasize the transmission of signals through a single or a few channels, while ultra-fine coaxial cable assemblies are more concerned with miniaturization, high density, multi-channel, and space utilization inside equipment. Ultra-fine coaxial cable assemblies combine multiple Micro-Coaxial Cables according to specific Pin positions, and then terminate them at both ends to form a complete cable assembly component that can be directly connected to the PCB of the equipment. Taking this product as an example, I-PEX 82984-100B-01-D uses a 50Pin structure, 0.4mm Pitch connector, AWG#40 Micro-Coaxial Cable, 50Ω characteristic impedance, and 200.0±5.0mm cable length, and defines the 1-1 pin position. Therefore, it is not just a finer version of traditional coaxial cables but a complete cable assembly solution designed for modern electronic devices with high-speed, multi-channel, and compact connection requirements.
From the perspective of engineering design, the greatest application difference between the two lies in the balance between space, high density, and high-speed signal transmission. Traditional coaxial cables, if using a thicker wire diameter, are prone to occupying a larger internal space when multiple channels are laid out simultaneously, whereas extremely thin coaxial cables can achieve multiple channel signal connections within a limited space. The CABLINE®-CA series adopts a 0.4mm contact spacing, horizontal insertion structure, mechanical lock, and shielding with multi-point grounding design. Data shows that it is suitable for internal connections of high-speed, miniaturized equipment and supports various wire diameter specifications of Micro-Coaxial Cable. For engineers, this kind of structure is conducive to compact wiring inside display devices, camera modules, industrial vision, AI equipment, and other high-density electronic systems; for purchasers, it means that when looking for substitute products, it cannot be simply compared with the three words "coaxial cable," but should further confirm whether the wire diameter, impedance, Pin number, connector structure, wire position definition, and cable length are consistent.
I-PEX 82984-100B-01-D is the core product material number/model for this product. The 50Pin cable uses AWG#40, 50Ω Micro-Coaxial Cable, with a cable length of 200.0±5.0mm. Both ends use the corresponding CABLINE®-CA connection structure, and the connector model used at the cable end is 20634-150T-02, with wire positioning defined as 1-1. "1-1" means that the Pin positions on both ends are connected according to the corresponding relationship, i.e., Pin 1 corresponds to Pin 1, and so on up to Pin 50. For engineers, these parameters together determine whether the cable can be matched with the original equipment; especially the 0.4mm pitch and 50Pin structure have higher requirements for PCB layout and connector space. For purchasers, I-PEX 82984-100B-01-D, 20634-150T-02, AWG#40, 50Ω, 200mm, and 1-1 should be quoted and supplier confirmed as a complete specification set, and not simply purchased based on "50Pin ultra-thin coaxial cable".
If it is necessary to find a domestic alternative for I-PEX 82984-100B-01-D, engineers are advised to first confirm the original equipment PCB connector and installation space, then check the connection structure of the cable end 20634-150T-02, and simultaneously confirm the 50Pin, 0.4mm Pitch, AWG#40, 50Ω, 200mm, and 1-1 wire position definitions. It is especially important to note that the CABLINE®-CA series has products with different pin counts, different cable lengths, and different wire position definitions, for example, in the 50Pin products, there are both 1-N configurations and 1-1 configurations. Therefore, even if the connector series is the same, it cannot be directly assumed that the cables can be interchangeable. Our company focuses on the production and manufacturing of extremely thin coaxial cables and can develop alternative compatibility based on the customer-provided connector, pin count, wire specification, cable length, wire position definition, and actual installation requirements. Our company can provide: I-PEX 82984-100B-01-D alternative cable solution. For purchasers, it is recommended to first confirm the mechanical match through samples and then perform signal integrity and other related verifications based on the actual high-speed signal application, thereby reducing the introduction risk of the alternative project.
