In high-speed signal transmission and precision electronic equipment design, micro coaxial cable, with its excellent shielding and signal integrity, has become the core connection method in consumer electronics, medical imaging, industrial detection, and other fields. Among its key parameters, "50Ω impedance" is almost the unified standard across the entire industry. This article will start from the impedance principle, analyze why 50Ω has become the mainstream design, and introduce the high-performance connector that perfectly matches it—the KEL XSLS20-40.
Part 1: Definition of Impedance and the Formation of the 50Ω Standard
Impedance refers to the "resistance" encountered by alternating current signals in transmission lines. During the signal transmission process, if the impedance of the transmission line does not match that of the equipment, reflections, echoes, signal distortion, and even data loss may occur, directly affecting the integrity of the signal and the stability of the system.
50Ω has become an industry standard because it achieves a good balance in the following aspects:
Strive to achieve the best compromise between power bearing and signal loss.
Low reflectivity can effectively reduce the echo of high-speed signals.
High compatibility, easy to process and match with systems.
Meet the general design requirements for radio frequency and high-speed digital signals.
In the high-speed environment of micro coaxial cables, the 50Ω impedance can maximize signal integrity and transmission efficiency, which has been a long-verified standard value in fields such as communication, CCTV, radar, etc.
KEL XSLS20-40: Designed for 50Ω ultra-thin coaxial cable束
In the application of ultra-fine coaxial cable bundles, the structural design of the connector directly determines the signal performance. The XSLS20-40 series connectors launched by KEL are specially designed for 50Ω micro coaxial cable, offering a small high-density interface. They are widely used in devices requiring high-frequency signal transmission, such as laptops, digital cameras, medical equipment, industrial robots, and more.
Main features of XSLS20-40 are as follows:
Supports 50Ω coaxial cable assemblies, matched to high-speed signal systems.
The design adopts a double grounding structure, with excellent shielding effect and high signal stability.
High insertion and extraction life, excellent durability, suitable for long-term operation.
Compact structure, small space occupation, meets the high-density layout requirements.
This connector provides a reliable interface solution for a 50Ω micro coaxial cable, and is a key component for achieving stable interconnection of high-frequency signals.
III. Technical Advantages of the ultra-fine coaxial cable束 + KEL XSLS20-40 combination
When used with the KEL XSLS20-40, a 50Ω micro coaxial cable can achieve stable transmission of high-speed data and radio frequency signals within a limited space. Its collaborative advantages are reflected in:
High impedance consistency, small signal reflection.
Good screening performance, strong anti-interference ability;
System EMI performance significantly improved.
Maintain excellent signal integrity in high-frequency, high-speed, and high-density applications.
It can be said that the setting of 50Ω impedance not only conforms to the electrical rules of transmission lines, but is also a practical standard verified by the industry over a long period of time. And the combination with high-quality connectors such as KEL XSLS20-40 is a key factor to ensure the reliability and signal performance of the product.
The 50Ω impedance standard of the micro coaxial cable is the foundation for stable transmission in high-speed signal systems. It achieves an ideal balance between signal integrity, anti-interference ability, and system compatibility. The KEL XSLS20-40 is a high-performance connector specifically designed for 50Ω ultra-thin coaxial cables, which can fully utilize the cable's potential and ensure accurate transmission of high-frequency data in miniature devices.
