With modern electronic products trending toward miniaturization and high integration, Pogo Pin spring probe connectors have become a highly efficient and flexible connection solution. They are widely used in smart wearables, mobile communications, industrial control systems, automotive electronics, and more. Depending on structural and functional differences, Pogo Pins can be classified into single-pin, multi-pin, double-ended, turned-pin, SMT type, and positioning-post variants—each designed to meet specific needs for contact reliability, durability, and space constraints.

Among them, the KH-PG203004-DZ model by Kinghelm stands out thanks to its ultra-compact 3.0mm length, excellent conductivity, and strict environmental adaptability testing, delivering higher stability and longer service life. It has become the preferred connector choice in many high-end electronic applications.

The KH-PG203004-DZ Pogo Pin spring probe connector by Kinghelm uses premium brass alloy for both the pin barrel and tip, combined with precision manufacturing to ensure low impedance and high conductivity throughout the current path. With a continuous operating current of up to 1A, it meets the current load needs of most compact electronic devices.

In solderability testing at 230±5°C for approximately 1 second, the product achieved over 95% wet solder coverage, ensuring excellent soldering performance. This significantly reduces the risk of cold solder joints or false soldering during production and improves overall assembly reliability.
Its corrosion resistance is also proven: the product passed a salt spray test in a 5% salt solution for 24 hours without rust, demonstrating robust long-term stability even in harsh environments.

From a packaging perspective, the KH-PG203004-DZ is supplied in bags with a net weight of only 0.023 grams, making it lightweight and convenient for large-scale automated mounting, transport, and storage. This helps reduce production costs while meeting the lightweight, miniaturized demands of modern smart hardware. Operating at a voltage below 12V@25°C, it suits most low-voltage electronics while effectively keeping power consumption low—enhancing safety and energy efficiency.

As one of Kinghelm’s best-selling models, it has been widely adopted in portable consumer electronics, smart wearables, medical instruments, test fixtures, battery connector modules, and other applications requiring high reliability.

In terms of structure, the KH-PG203004-DZ is carefully engineered for stability and durability: its built-in spring design maintains consistent contact pressure during connection, minimizing fluctuations in contact resistance and extending service life. Thanks to strict material selection and process control, this model retains excellent electrical performance even after frequent mating cycles—making it particularly suitable for products requiring repeated assembly or testing. For manufacturers, choosing the KH-PG203004-DZ also means fewer after-sales issues and higher customer satisfaction.
