In response to the trend of continuously compressed internal space and continuously increased signal rates in high-speed electronic devices, the I-PEX CABLINE®-CA II PLUS 60Pin ultra-thin coaxial cable harness solution balances high-density wiring, high-speed signal transmission, and electromagnetic compatibility requirements. Among them, the I-PEX 82872-100B-02-D belongs to the CABLINE®-CA II PLUS 60Pin Micro-Coaxial Harness, which uses a cable harness scheme with **AWG#40 ultra-thin coaxial cable, 60Pin, L=300mm, 1-N (one end connected)**. I-PEX official materials also show that this series of 60Pin solutions adopts a full EMI shielding ZenShield® structure and supports mechanical locking clips; the 82872-100B-02-D is also listed as an official sample evaluation cable harness model. For engineers, the value of this type of cable harness is not just "connecting 60 signal paths," but more importantly, achieving stable transmission of multi-channel high-speed signals within the limited internal space of the device; for purchasers, it is necessary to focus on confirming whether the Pin count, wire material AWG, connector model, cable length, termination form, and bulk supply capacity can match the original design.
Why can extremely thin coaxial cables resist EMI? The core reason lies in the fact that it is not just a simple signal line, but a coaxial structure composed of "center conductor + insulating layer + metal shielding layer + external protective structure," which confines high-speed signals to a relatively controllable electromagnetic environment. The center conductor is responsible for transmitting the signal, while the outer shielding layer plays a crucial role in electromagnetic shielding and return path, which can reduce the coupling of external electromagnetic noise to internal high-speed signals and also reduce the electromagnetic radiation generated by high-speed signals in the surrounding space. Especially in 60Pin high-density cable harnesses, where multiple signals are very close to each other, it is more likely to occur cross-talk, EMI, and signal integrity issues if there is a lack of reasonable shielding and grounding design. CABLINE®-CA II PLUS itself adopts ZenShield® full EMI shielding technology and is complemented by a mechanical locking structure, which is beneficial for meeting the requirements of high-speed, high-density equipment for EMC and connection reliability. Therefore, from the perspective of engineering design, the shielding layer of extremely thin coaxial cables is not an "additional structure," but an important part of the high-speed signal transmission chain; from the perspective of procurement, it is also not enough to pay attention to the outer diameter and price of the wire material, but also to pay attention to the shielding structure, termination technology, and batch consistency.
The wire harness connector model used with I-PEX 82872-100B-02-D is 20680-060T-01, which corresponds to CABLINE®-CA II PLUS 60Pin Plug Housing; I-PEX official documentation explicitly lists 20680-060T-01 as a 60Pin Plug Housing, and related assembly documents also treat it as the Housing Assembly for CABLINE®-CA II PLUS Plug. This solution uses AWG#40 ultra-fine coaxial cable, and I-PEX data indicates that AWG#40 in this series can achieve a rated current capacity of 0.3A/contact, with a maximum of 60 contacts. For engineers, when performing compatibility and replacement design, it is important to check the 60Pin arrangement, wire AWG, termination size, impedance, and high-speed signal integrity, while also focusing on the reliable connection between the shielding layer and the connector shielding structure; for purchasers, it is recommended to clearly specify key conditions such as “I-PEX 82872-100B-02-D, 20680-060T-01, AWG#40, 60Pin, 300mm, 1-N” when inquiring about prices to avoid specification discrepancies caused by purchasing only based on “60Pin ultra-fine coaxial cable bundle”. Based on the same application requirements, our company can provide: I-PEX 82872-100B-02-D compatible replacement cable assembly solutions, which can be developed for domestic compatibility and replacement around the original model's connector, AWG#40 cable, pin count, cable length, and termination requirements, providing cable manufacturing support for engineering verification, sample making, and bulk purchasing.
For engineers and purchasers preparing to import an alternative solution for the I-PEX 82872-100B-02-D, it is recommended to first confirm that the actual requirement on the device side is a 60Pin, AWG#40 Micro-Coaxial, 300mm, 1-N configuration, and then confirm whether the connector on the cable side uses 20680-060T-01 and the corresponding board-side connector system; if there are high-speed USB, DisplayPort, HDMI, eDP, or other high-speed differential signals inside the device, further verification of impedance, insertion loss, return loss, crosstalk, and EMI should be carried out, rather than simply judging "can be replaced" based on mechanical dimensions. The official materials of CABLINE®-CA II PLUS list reference high-speed applications covering USB4 Gen4, Thunderbolt 5, USB4 Gen3, DisplayPort UHBR20, HDMI 2.1, eDP, and explicitly adopt ZenShield® full EMI shielding design. Therefore, the domestic alternative is more suitable to be promoted in a way of "connector matching + AWG#40 wire matching + line length/Pin number matching + termination process control + high-speed performance verification," rather than simply replacing a line harness with a similar appearance. Our company can provide corresponding ultra-fine coaxial cable compatible alternative and customized manufacturing solutions according to the customer's device structure, wire length, Pin number, and application requirements.
