In an era where electronic products are trending toward greater compactness and integration, the KH-191112-TP stands out with its excellent electrical performance and mechanical stability, making it a preferred choice for engineers designing antenna contact solutions.

To ensure superior conductivity and corrosion resistance, Kinghelm has applied high-quality gold plating to the contact area. This low-contact-resistance surface supports stable high-speed and high-frequency signal transmission, effectively preserving signal integrity and reducing long-term signal loss. Compared to conventional contact springs, this gold-plated version performs more reliably under harsh conditions such as high temperature, high humidity, and frequent mating cycles.

Constructed from high-resilience stainless steel SUS301, the KH-191112-TP antenna contact spring offers outstanding mechanical strength and elastic recovery, maintaining stable contact force without permanent deformation. The inherent corrosion resistance of SUS301 also ensures reliable operation in industrial environments, and its stability in manufacturing contributes to the precision and consistency of the product’s dimensions and performance.

As a key member of Kinghelm’s precision connector series, the KH-191112-TP antenna contact spring continues the brand’s commitment to high-accuracy manufacturing and robust electrical performance. With a unit weight of just 0.038 grams, it’s clearly tailored for ultra-compact device applications.

This product has been widely adopted in fields requiring high integration and high reliability, including Bluetooth earphones, TWS charging cases, smartwatches, navigation modules, communication modules, and smart home devices.
