Pogo Pins, also known as spring probes, are high-performance connectors that achieve reliable electrical contact through an internal precision spring mechanism. Based on the shape of the tip and different application needs, Pogo Pins can be categorized into several types: the most common include dome-shaped, flat-head, and blade-type, as well as special variants such as long pins, short pins, high-current pins, double-ended pins, and side-entry pins. Each type is designed to meet varying requirements for installation space, current capacity, and contact performance, serving the modern demands of miniaturization, high-density wiring, and high reliability in electronic devices.

KH-PG203505-DZ, launched by Kinghelm, is a representative model that stands out for its compact 3.5mm length, excellent conductivity, and superior corrosion resistance—making it a popular choice in many precision electronics.

The Kinghelm KH-PG203505-DZ features both pin tip and barrel made of premium brass alloy, providing outstanding electrical conductivity and wear resistance. This effectively lowers contact resistance and improves current transmission efficiency. With a maximum continuous operating current of up to 1A (at working voltage below 12V@25°C), it is especially suitable for applications that require highly reliable connections in space-constrained designs—such as smart wearables, automotive electronics, medical equipment, and consumer electronics.

To ensure stability and reliability in harsh environments, the KH-PG203505-DZ undergoes rigorous reliability tests:

Salt spray test: with no rust after 24 hours in a 5% salt solution, providing excellent long-term oxidation resistance.

Solderability test: achieving over 95% wet solder coverage within 1 second at 230±5°C, ensuring smooth downstream soldering processes and reducing risks of cold or dry solder joints.

These features enable excellent performance during final assembly and help extend the overall lifespan and reliability of end products.

As a small, bagged packaging product, the KH-PG203505-DZ is highly compact and well-suited for high-density PCB layouts. It saves valuable board space and allows for flexible product design, making it perfect for multi-point contacts, battery spring interfaces, charging docks, test probes, and more. Additionally, Kinghelm’s commitment to precision manufacturing ensures the product maintains stable elasticity and low elastic fatigue over frequent, long-term use.

Behind its high reliability and excellent electrical performance lies Kinghelm’s long-term dedication to material selection, optimized manufacturing processes, and strict quality control. The KH-PG203505-DZ not only offers tight dimensional tolerances and high product consistency but also supports fast mass production, making it a rare Pogo Pin connector that balances both performance and cost-effectiveness in the market.
