Categorization：Harness Component
In high-speed electronic devices, the signal rate is constantly increasing, and the harness is no longer just a simple "conductive connector." Its impedance consistency, shielding performance, signal attenuation, and termination process all affect the final signal integrity. The extremely thin coaxial cable uses a central conductor, insulating layer, and shielding structure, allowing high-speed signals to be transmitted in a relatively stable transmission environment, while also being conducive to controlling external electromagnetic interference and crosstalk. For engineers, the design of high-speed harnesses requires comprehensive consideration of wire impedance, AWG wire diameter, transmission length, connector matching, and terminal processing quality; for purchasers, it is necessary to pay attention to whether the supplier can stably control these key parameters. Therefore, in the internal circuits of high-speed displays, industrial vision, AI vision, and other high-speed data devices, the extremely thin coaxial cable harness has become an important connection scheme that takes into account both high-speed transmission and space utilization.
This product introduced is I-PEX 82450-100B-02-D, which belongs to the CABLINE®-VS 50Pin ultra-thin coaxial cable assembly. According to the corresponding product drawings, this cable assembly uses 50-core AWG#40, 50Ω Micro-Coaxial Cable, with the wire color being blue. The finished length is 200.0±5.0MM, and both ends are equipped with CABLINE®-VS connector components, where the connector model for the wire end is the 20454-250T series. The wire sequence of this product is defined in reverse 1:1, that is, one end Pin 50 corresponds to the other end Pin 1, one end Pin 49 corresponds to the other end Pin 2, and so on. When engineers are doing alternative design, they cannot simply confirm "50Pin+200MM", but should also synchronize to check parameters such as AWG#40, 50Ω impedance, wire sequence, and connector components, in order to ensure that the alternative cable assembly matches the original equipment interface and high-speed signal chain.
CABLINE®-VS employs a 0.5mm Pitch horizontal insertion structure with an installation height of approximately 1.0±0.1mm, and features a mechanical locking clip design, making it suitable for devices with compact space and high requirements for connection reliability. For the 82450-100B-02-D, a 200MM wire length means that engineers need to pay attention to the signal loss caused by transmission distance, and control the quality of high-speed signals through reasonable wire impedance, shielding structure, and termination technology. Especially in high-speed link applications, the manufacturing consistency of extremely fine coaxial cable assemblies is very important, and the welding, insulation treatment, UV glue fixing, and cable assembly arrangement at the connector end will affect the consistency of the finished product. Therefore, it is recommended to combine impedance, insertion loss, return loss, and crosstalk signal integrity tests with the equipment platform during actual project introduction, rather than solely judging whether the connection or wire material parameters can meet the high-speed transmission requirements.
For the compatibility alternative of I-PEX 82450-100B-02-D, engineers and purchasers are recommended to check in the order of "product part number → Pin quantity → wire specification → impedance → length → wire sequence → connector → end structure". Key parameters include 50Pin, AWG#40, 50Ω, 200MM, reverse 1:1 wire sequence, and 20454-250T series connectors; it is also necessary to confirm whether the structure of the connector body, metal shell, rod, Bonding, and tape fixing matches the original application. Our company focuses on the production and manufacturing of extremely thin coaxial cable assemblies and can carry out compatibility development and mass production according to customer drawings, samples, and technical requirements. Our company can provide I-PEX 82450-100B-02-D compatibility alternative cable assembly solutions to help customers with sample verification, domestic substitution, and second supplier introduction, thereby reducing procurement costs and improving supply chain flexibility.
