The Kinghelm KH-340920-TP PCB spring contact measures only 3.4 x 0.9 x 2.0 mm and weighs just 0.057 grams, making it ideal for precision equipment with strict size and weight requirements. Though small, its materials and craftsmanship are far from simple: made from SUS304 stainless steel, it offers excellent mechanical strength and corrosion resistance. The surface undergoes rigorous treatment with a nickel plating base layer of 50–80 μm and a full gold plating ≥1 μm on top. This ensures stable electrical conductivity while effectively resisting oxidation and wear.

For high-end electronics, connector performance stability is critical. The KH-340920-TP excels in durability, having passed strict tests to achieve more than 20,000 reliable elastic cycles, fully meeting long-term use demands. Its designed spring force is controlled between 60gf and 80gf, guaranteeing secure contact without exerting excessive pressure that could reduce device lifespan.

The KH-340920-TP also adapts well to complex operating environments: it meets the 48-hour salt spray test corrosion resistance standard, ensuring stable performance in humid or corrosive conditions. Additionally, it has passed reliability tests including twisting at 45°/1000mm and arching at 5mm/1000mm, maintaining excellent contact even under minor vibrations or thermal expansion and contraction.

These small but vital details are key to ensuring stable, efficient signal transmission. Whether in mobile communication terminals, automotive antenna modules, smart wearable devices, or other applications demanding miniaturization and high reliability, the KH-340920-TP plays a crucial role by providing stable, low-loss electrical connections, helping products deliver an enhanced user experience.

Thanks to tape-and-reel packaging, the KH-340920-TP PCB spring contact also supports efficient placement on automated production lines, significantly improving manufacturing efficiency and reducing labor costs, meeting the needs of large-scale production.

As a brand specializing in the R&D and manufacturing of connectors and RF components, Kinghelm consistently adheres to high standards in material selection and rigorous testing to ensure every product demonstrates outstanding quality in real-world applications. The KH-340920-TP is not just a tiny PCB spring contact but a symbol of Kinghelm’s commitment to quality and craftsmanship.
