High-speed data transfer and miniaturized interconnect solutions are increasingly important in modern electronic product design. For system designers who need dense signal channels, high EMC performance and reliable insertion and removal, the ultra-fine coaxial wire harness assembly (Micro Coax Cable Assembly) is a key component connecting the main control and RF/high-speed modules. Models like I‑PEX 82287 ‑100B‑02 ‑D CABLINE ‑CA II HAR 30P are widely used in these applications. This article focuses on the technical characteristics of the I-PEX 81461-100B-02-D model and the alternative solutions we can provide to provide reference for engineering selection.

1. product background and typical applications

81461-100B-02-D is I-PEX CABLINE®-CA II series is a 30-pin extremely thin coaxial harness assembly with Plug-to-Plug connection at both ends and a total length of about 200mm(0.656 ft). It is commonly used in scenarios such as high-density board connection, high-speed link between modules, embedded system interconnection, etc. The component has the following engineering key features:

1.1. Ultra-fine spacing design: 0.40mm connector spacing, suitable for high-density layout.

1.2, micro coaxial cable structure: usually use AWG40 coaxial line, support high frequency signal transmission and excellent EMI performance.

1.3, shielding and reliability: fully shielded design and locking structure, is conducive to anti-interference and stable connection, suitable for data links, radio frequency or high-speed digital lines.

In engineering practice, designers need to ensure that connectors can not only meet the layout requirements under space constraints, but also provide sufficient margin in signal integrity. Therefore, such micro-components have become the standard option for micro-module design.
