Designed specifically for high-density PCB layouts, the KH-2FH-2X13P-H4.3-SMT is optimized in both structure and specifications to ensure practicality and compatibility. The connector adopts a 2×13-pin dual-row configuration, enabling simultaneous multi-channel signal and current transmission. Compared with single-row headers, it achieves higher transmission efficiency within the same mounting footprint, making it suitable for PCB designs with multi-module integration. Its U-shaped structure, combined with a plastic height of 4.3 mm, accommodates different PCB stacking requirements while minimizing vertical space occupation, aligning with the ongoing trend toward compact electronic designs.

The product uses SMD mounting technology with a 2.0 mm pin pitch, representing a compact spacing solution. Compared with conventional 2.54 mm pitch connectors, it effectively increases PCB routing density, helping engineers optimize board layouts and reserve more space for other critical components. Precisely controlled dimensional parameters such as W4.5, PC6.5, and PB4.6 ensure accurate matching with PCB pads, reducing placement deviation risks and supporting automated SMT production. This improves consistency and efficiency in mass manufacturing. With a single-piece gross weight of only 1.3 g, the lightweight design helps reduce overall device load. The product is supplied in tube packaging, facilitating storage, transportation, and automated feeding in large-scale production environments.

Electrical performance is fundamental to connector reliability. The KH-2FH-2X13P-H4.3-SMT delivers balanced electrical characteristics suitable for a wide range of applications. With a rated current of 1.5 A, it meets the current transmission needs of small and medium-sized electronic devices while helping prevent failures caused by overload. A maximum contact resistance of ≤20 mΩ minimizes signal loss during transmission, ensuring signal continuity and stability and reducing the risk of interruptions due to poor contact. The insulation resistance is ≥1000 MΩ, and the dielectric withstanding voltage reaches AC 500 V, enhancing electrical safety and effectively preventing short circuits or leakage caused by insulation failure under different operating voltage conditions.

In terms of materials and manufacturing, this female header follows Kinghelm’s strict quality control standards with clearly defined specifications. The contacts are made of brass, offering good electrical conductivity, structural strength, and appropriate mechanical elasticity to support rated current and improve mating durability and contact stability. Flash gold plating is applied to reduce contact resistance and enhance oxidation and corrosion resistance, ensuring long-term signal reliability. The insulating housing is made of polyester material compliant with the UL 94V-0 flame retardant standard, providing high electrical safety and resistance to SMT reflow soldering temperatures, preventing deformation or aging during assembly. Manufactured in accordance with PA6T standards, the product delivers stable mechanical strength and corrosion resistance, making it suitable for applications in industrial control, consumer electronics, and other demanding environments.

Thanks to its compact structure and stable performance, the KH-2FH-2X13P-H4.3-SMT supports a wide range of applications, particularly in devices using high-density PCBs. In consumer electronics, it can be used for interconnections between mainboards and functional modules in devices such as smart wearables, tablet computers, and compact routers, balancing space efficiency with reliable transmission. In industrial control systems, it is suitable for small PLC controllers and sensor modules, offering resistance to environmental interference and ensuring stable operation. In communication equipment, it can be applied to board-to-board connections in compact communication modules, reducing signal loss and supporting high-frequency signal transmission. Additionally, the product is suitable for medical auxiliary equipment and intelligent testing instruments that require compact size and high connector reliability.

As an important product within the Kinghelm connector portfolio, the KH-2FH-2X13P-H4.3-SMT precisely addresses the requirements of high-density PCB designs. With its compact structure, well-balanced electrical performance, and reliable quality, it serves as a practical option for engineers during component selection. As electronic devices continue to advance toward higher integration and smaller form factors, compact connectors that balance space utilization and transmission stability are expected to see broader adoption. Through continuous optimization of connector technologies and close alignment with market demands, Kinghelm provides reliable interconnection solutions that support technological upgrades across the electronics industry.
