The Pogo Pin spring probe connector KH-PG205505-DZ, developed by Kinghelm, is a high-performance connector specifically designed for advanced electronic devices. With a pin length of just 5.5mm, it combines a compact structure with outstanding performance. This model features a brass alloy barrel and tip, ensuring excellent electrical conductivity and mechanical strength. It can continuously carry a 1A current and supports an operating voltage below 12V@25℃, making it an ideal choice for applications that demand compact size and high reliability. Compared to traditional connectors, the key advantages of Pogo Pin spring probes include strong contact elasticity, wear resistance, compact design, and easy assembly. These make them especially suitable for electronic products that require frequent mating or have limited space, such as smartwatches, medical devices, mobile communication equipment, and automotive electronics.

Kinghelm KH-PG205505-DZ Pogo Pin connector is also subject to stringent quality testing. The product has successfully passed a 5% salt solution 24-hour salt spray test without rust, demonstrating strong corrosion resistance. Even in humid or corrosive environments, it maintains stable performance. Furthermore, its solderability test results are impressive: under conditions of 230+5℃, it achieves a wet solder coverage rate of over 95% within 1 second. This not only ensures production efficiency but also enhances the reliability of solder joints during subsequent use. The use of high-quality brass alloy for both the barrel and tip provides excellent conductivity along with superior mechanical properties, including resistance to stretching, bending, and wear, which effectively extends the product’s service life.

Each connector weighs only about 0.05 grams and comes in bag packaging, making it convenient for storage and transportation, as well as suitable for bulk procurement. With a pin length of just 5.5mm, the KH-PG205505-DZ Pogo Pin connector can be easily integrated into products with stringent space requirements while still delivering excellent electrical connectivity. In devices requiring rapid testing or frequent connections, the built-in spring structure of the Pogo Pin ensures stable contact pressure, significantly reducing the risk of poor contact and lowering daily maintenance costs. Unlike fixed pin designs, spring probes can accommodate slight positional deviations, improving overall assembly tolerance and resulting in higher production efficiency and yield.

The application range of Pogo Pin connectors is extensive—from consumer electronics to industrial equipment, medical diagnostic instruments, and automotive communication modules. The combination of high reliability and compact design in the KH-PG205505-DZ ensures excellent performance in smart hardware, miniaturized devices, and portable terminals. For manufacturers who prioritize stable product performance and user experience, this spring probe connector is an ideal choice to optimize structural design and enhance product competitiveness.
