Designed for through-hole mounting with tray-based packaging, this connector supports streamlined, high-efficiency SMT or DIP production lines, reducing assembly error rates while enhancing throughput. Built to SMA interface standards, it delivers excellent compatibility and can seamlessly replace other SMA connectors of the same class. The offset pin layout, combined with a female center contact, ensures flexible adaptation to constrained PCB routing, making it particularly suited for compact device designs where space is at a premium.

A standout advantage of the KH-SMA-KEB16.5-P1.3 SMA PCB connector lies in its precise pin pitch and robust mechanical characteristics. The 1.3mm pin spacing enables high connection density while maintaining excellent insulation and electrical stability, reducing the risks of crosstalk and short circuits. The extended 16.5mm length improves insertion force control and enhances mechanical anchoring—ideal for applications requiring frequent mating cycles or long-term fixed installations. Weighing only 2.174g, it strikes the perfect balance between lightweight design and structural durability.

Addressing key pain points in the industry—such as size incompatibility, difficult soldering, and poor mechanical endurance—the KH-SMA-KEB16.5-P1.3 introduces optimized pin configuration and enhanced materials, supporting stable high-frequency signal transmission up to 18GHz. The design also incorporates electromagnetic compatibility (EMC) considerations, effectively suppressing high-frequency interference and boosting system-wide signal purity and anti-jamming capability.

From a technical perspective, Kinghelm utilizes high-precision CNC-machined copper and advanced metal plating to ensure excellent conductivity and corrosion resistance. The internally machined female socket supports over 500 mating cycles while maintaining consistent contact resistance and mechanical integrity, far exceeding industry norms. The offset-pin board interface increases soldering contact area and structural strength, mitigating risks of poor contact due to vibration or thermal cycling.

On the customization and supply side, Kinghelm offers strong R&D and manufacturing capabilities to rapidly tailor pin pitch, connector length, packaging format, and electrical characteristics to meet needs across consumer electronics, and industrial machinery. With a well-established logistics and warehousing network in Shenzhen, Kinghelm supports short lead times, stable stock availability, and seamless bulk procurement—easing inventory pressure for downstream customers.

In line with ongoing trends in the RF connector market—miniaturization, high-frequency operation, and modular design—the KH-SMA-KEB16.5-P1.3 stands out as a well-rounded solution. Its performance parameters meet demanding signal transmission standards, while its structural design improves assembly efficiency and device compatibility, making it a go-to option for cost-effective, high-performance applications.
