This spring contact is made of high-strength SUS301 stainless steel, featuring excellent elasticity and mechanical strength. It withstands twisting of 45° per 1000 mm and arch deformation of 5 mm per 1000 mm, delivering stable and reliable performance. With a lifespan exceeding 20,000 cycles, it guarantees long-term durability and greatly reduces maintenance and replacement frequency. The plating process is strictly controlled, with a nickel base layer thickness between 50 and 80 microns. Both the welding and contact areas are gold plated, with the contact area gold thickness no less than 1 micron, ensuring low contact resistance and oxidation resistance, effectively safeguarding stable and efficient signal transmission.

In complex environments such as automotive terminals and vehicle networking modules, the KH-35309155-TP PCB spring contact also performs excellently. It has passed a 48-hour salt spray test, demonstrating superior corrosion resistance, capable of withstanding humidity and salt fog erosion, ensuring long-term stable operation of connectors under harsh conditions. Its tape-and-reel packaging suits high-speed surface-mount technology (SMT) production lines, facilitating automated mass production, improving manufacturing efficiency, and reducing costs to meet the dual demands of quality and efficiency in modern manufacturing.

Additionally, the KH-35309155-TP’s design fully considers ease of integration and installation in real applications, allowing quick adaptation to various terminal devices, shortening production cycles, and enhancing assembly flexibility. Whether in consumer-grade smart wearables or stringent automotive electronic systems, this product delivers both performance and quality assurance.
