Price Difference Analysis of Extremely Fine Coaxial Cable Assemblies and I-PEX 20373-R50T-06 Application Guide

In the field of high-speed signal transmission and high-density device connections, extremely thin coaxial cables (Micro Coaxial Cable) are widely used in scenarios such as laptops, tablets, in-car central controls, industrial cameras, and medical equipment due to their high speed, high reliability, and excellent anti-interference performance. The I-PEX 20373-R50T-06 connector, as an important model in the CABLINE®-SS series, is specifically designed for micro coaxial cables and is highly favored by engineers. However, many users may find that there is a huge price difference among products of the same specification when purchasing micro coaxial cables. What are the reasons behind this? This article will explain it for you.

The Six Truths About the Price Differences of Extremely Fine Coaxial Cable Assemblies

Material materials are different.

High-quality wire harnesses use high-purity silver-plated copper conductors and low dielectric loss insulating materials to ensure stable signals and long lifespan. Low-priced products often use copper-clad aluminum or inferior FEP, which results in significant signal attenuation and is prone to aging.

Processing technology standard differences

The micro coaxial cable束welding process is complex. High-quality products have delicate welding points, neat wiring, complete EMI shielding layer, and strong anti-interference ability. Low-end products have rough technology and are prone to false welding, short circuits, and interference issues.

③ Differences between original and counterfeit connectors

I-PEX original factory connectors (such as 20373-R50T-06) have excellent conductivity performance and high resistance to insertion and removal. Counterfeits may look similar, but they have large conductivity resistance, are prone to looseness, and pose hidden dangers for long-term use.

④ Differences in detection standards and testing equipment

High-quality manufacturers conduct conductance tests, bend resistance tests, high and low temperature cycles, and EMI tests before shipment to ensure product stability and reliability. Low-priced products often lack testing procedures, and quality cannot be guaranteed.

⑤ Harness customization difficulty and assembly technology

The micro coaxial wire has an extremely thin diameter (0.3-0.5 mm), and high-precision operations are required for layout, welding, cutting, and assembly. Complex customization and multiple interfaces will directly increase the cost.

⑥ Cost Difference between Small Batch and Large Batch Production

The larger the production batch, the lower the unit cost. Some low-priced products rely on large-scale supply to drive down prices, resulting in poor quality. High-quality cables can support small batch customization, but after the cost of process adjustment and inspection is allocated, the unit price is relatively high.

Section 3: Matters to Be Mindful Of During Procurement

Behind the price differences of extremely thin coaxial cable束, factors such as materials, technology, testing standards, and the authenticity of accessories are involved. When purchasing, it is important to pay close attention to:

Choose I-PEX connectors from the original factory or authorized suppliers to ensure good conductivity and insertion/extraction life.

Confirm the material and shielding quality of the wire, ensure stable signal transmission

Evaluate the supplier's detection capability, including continuity testing, bend resistance, high and low temperature, and EMI testing

Select suppliers based on batch and customization requirements, balancing cost and reliability.

The performance and stability of miniature coaxial cables directly affect the signal quality of high-speed equipment. The price differences are not only due to material and process variations but also involve differences in original factory connectors and testing standards. Choosing the I-PEX CABLINE®-SS 20373-R50T-06 connector with high-quality ultra-thin coaxial cables can ensure stable high-speed signals and long-term reliable operation of the equipment.
