The standout feature of this product is its right-angle full-thread jack design, which enhances contact stability and vibration resistance. The 9.5mm threaded length ensures strong mechanical retention during mating, reducing the risk of signal attenuation due to poor contact—especially valuable in environments exposed to frequent movement or high-frequency signals. Its through-hole plug-in packaging simplifies PCB installation and replacement, improving assembly efficiency. The connector is supplied in trays of 250 units, making it well-suited for mass production and automated assembly lines.

The Kinghelm KH-SMA-KWEQ9.5 SMA connector has successfully passed the 48-hour neutral salt spray test, making it particularly suitable for applications requiring corrosion resistance, such as marine electronics, industrial control systems, and outdoor base stations. Its straight-pin female contact ensures precise mating with standard RF modules and sockets, reducing signal loss and enhancing data transmission efficiency. Weighing just 5.8648 grams, this connector balances mechanical strength with the growing demand for lightweight device design.
