Designed with a through-hole mounting structure, the Kinghelm KH-SMA-KE8-G1.3 SMA connector ensures easy installation and reliable connectivity, making it well-suited for complex PCB layouts with space constraints and high wiring density. Its 1.3mm pitch terminal design enhances compatibility and flexibility for compact, high-integration electronic devices. The semi-threaded straight female structure improves connection stability and provides strong vibration resistance, making it ideal for high-vibration environments such as automotive communications. With precision mechanical design and high-quality gold-plated materials, this connector guarantees low signal loss and stable transmission, ensuring long-term high performance.

In RF connector applications, it’s often the “invisible performance” that determines system stability and safety. The KH-SMA-KE8-G1.3 SMA connector excels in this regard, supporting frequencies above 6GHz, making it ideal for high-frequency signal module connections. Kinghelm leverages advanced RF simulation and stringent return loss control to maintain low reflection and excellent impedance matching under high-frequency transmission—meeting the rigorous S-parameter requirements of 5G small base stations, microwave communications, and aerospace navigation systems.

Equally impressive are the mechanical properties of the KH-SMA-KE8-G1.3. With an insertion lifespan of over 500 mating cycles, a contact resistance below 20mΩ, and an insulation resistance up to 1000MΩ, it minimizes signal interference and attenuation. Made from high-strength copper alloy with gold plating, it offers excellent conductivity and corrosion resistance, significantly extending product lifespan and reducing maintenance costs.

As a representative of high-performance connectors made in China, the KH-SMA-KE8-G1.3 aligns perfectly with the national trend toward domestic substitution and supply chain autonomy. With in-house R&D, precision tooling, and complete production lines, Kinghelm provides a full range of services from product customization and structural optimization to bulk delivery. For non-standard requirements like special pin pitches, angled configurations, or impedance tuning, Kinghelm offers fast turnaround and tailored solutions, enhancing system reliability and development efficiency.

From a supply chain perspective, Kinghelm maintains robust supporting resources and a stable inventory system, enabling flexible production from low-volume prototyping to high-volume manufacturing. Certified under multiple quality systems including RoHS and ISO9001, Kinghelm’s connectors are widely used across academic research, defense equipment, and new energy vehicles, offering dependable long-term partnership value.
