The Kinghelm KH-SMA-KWE11 is a half-thread right-angle SMA PCB connector specially designed for high-frequency RF signal transmission. Featuring a right-angle plug-in design, it allows flexible installation on space-constrained circuit boards, perfectly meeting the modern electronics demand for compact size and stable performance. The connector housing is made of gold-plated brass, the inner conductor is crafted from gold-plated HPb59-1 copper alloy, and the insulator uses high-quality PTFE material. This combination ensures excellent conductivity, corrosion resistance, and low signal loss while fully complying with RoHS environmental standards.

Regarding applications, the half-thread right-angle SMA female connector plays a critical role in wireless communication, base station equipment, GPS positioning systems, and various test and measurement instruments. For example, in base station antenna RF signal transmission, device space is often extremely limited. Straight connectors can make the overall structure bulky, whereas this right-angle plug-in design cleverly “bends” the connection to save space, ensuring stable signal transfer and a more compact, efficient layout. Many manufacturers face the dilemma of choosing between “good performance but limited space” or “compact design but signal degradation.” The KH-SMA-KWE11’s 11mm height design perfectly resolves this conflict, maintaining sufficient mechanical clearance without compromising signal quality.

From a technical perspective, this connector’s dimensional tolerance is controlled within ±0.2mm, guaranteeing precise assembly and long-term stability. The right-angle plug-in structure is ideal for side access at the circuit board edge, effectively saving valuable PCB space and reducing mechanical stress to prolong connector lifespan. If space permits, straight plug-in installation with an adapter is also a viable option, providing direct signal paths at the cost of greater space requirements. Both installation methods have their merits, allowing users to flexibly choose based on actual needs.

In terms of packaging and weight, the KH-SMA-KWE11 is bag-packed to facilitate transport while preventing contamination and damage during logistics. Each connector weighs only 2.619 grams, offering an added advantage for devices emphasizing lightweight design. Overall, this half-thread right-angle SMA female connector has earned a strong reputation in the RF connector field due to its thoughtful design, premium materials, and precise manufacturing. Whether in space-restricted wireless communication devices or signal-sensitive test instruments, it delivers a stable and reliable connection solution.
