The KH-DC-012-2.5L DC power jack adopts a through-hole mounting design, making it easy to solder onto PCB boards, suitable for both automated assembly and manual assembly processes, which greatly enhances assembly efficiency. Its compact design and small size, with a product weight of only 1.594 grams, make it ideal for electronic systems with limited space. The bagged packaging is also convenient for manufacturers to manage and distribute in bulk, reducing packaging space.

One notable advantage of this model is its 2.5mm inner diameter and 6.3mm outer diameter contact structure. Compared to conventional 2.0mm connectors, the 2.5mm interface provides a larger contact area, increasing the connection strength and resistance to loosening from frequent insertions and removals. It is compatible with most standard DC plugs on the market, effectively solving contact issues caused by incompatible specifications. For applications that require frequent plugging and unplugging, such as security monitoring devices, portable speakers, and handheld terminals, this jack provides stable performance.

In terms of conductivity, the KH-DC-012-2.5L DC power jack maintains Kinghelm's consistent high-quality craftsmanship, utilizing premium metal contact materials to ensure low resistance and high-conductivity current transmission. While the electrical parameters for rated current and voltage are not explicitly stated, the design and materials are compatible with mainstream DC connectors that operate within 30V and below 1A, making it suitable for the daily power supply needs of low-power devices.

Moreover, the KH-DC-012-2.5L DC power jack features a housing made from high-strength insulating materials, offering excellent flame resistance, impact resistance, and high-temperature performance, making it suitable for long-term stable operation in various environmental conditions. It is not only suitable for industrial-grade equipment but also widely used in consumer electronics, becoming an indispensable connector component for R&D engineers and manufacturers during product design and upgrades.
