Kinghelm KH-351538-TP PCB spring contact is made from premium SUS304 stainless steel, providing excellent conductivity along with superior corrosion resistance and mechanical strength. Even in complex usage environments, it maintains stable form and reliable conductivity over time. For example, the product can withstand torsion of 45°/1000mm and arching of 5mm/1000mm without losing elasticity, ensuring highly reliable electrical connections.

Moreover, this PCB spring contact has passed rigorous life cycle testing, withstanding over 20,000 insertion and removal cycles while consistently maintaining a spring force between 60gf and 80gf. This exceptional fatigue resistance makes the KH-351538-TP especially suitable for applications with frequent mating cycles or high vibration, such as automotive communication modules, IoT terminal devices, and high-frequency wireless modules—helping engineers address contact reliability even after prolonged use.

In terms of electroplating process, the KH-351538-TP demonstrates Kinghelm’s commitment to high standards: it features a nickel undercoat of 50–80μmin to improve corrosion resistance, and both soldering and contact areas are gold plated. Notably, the contact area has a gold thickness of up to 3U"MIN, which effectively lowers contact resistance and improves conductivity stability. This is particularly critical for high-frequency signal transmission, reducing signal loss and enabling faster, more stable data transfer.

Additionally, the KH-351538-TP uses tape-and-reel packaging, supporting automated SMT assembly, significantly enhancing production efficiency and reducing manual assembly errors. Compact and lightweight at only about 0.1 grams, it perfectly aligns with modern electronic product trends toward lightweight and miniaturized designs.

Kinghelm has always been dedicated to providing customers with reliable, high-quality RF connection products. The KH-351538-TP PCB spring contact embodies this commitment—through precise design, strict manufacturing processes, and premium materials, it offers more stable and durable electrical connections for various antenna systems. Whether in smart home devices, automotive electronics, or industrial IoT equipment, this spring contact plays a crucial role, helping products stand out in competitive markets.
