Standard 2.54mm Pitch for Broad Compatibility

The KH-2.54PH180-1X30P-L11.5 is a single-row, 30-pin, straight-through pin header featuring a standard 2.54mm pitch layout. This makes it fully compatible with most pin sockets, Dupont cables, adapter boards, and other PCB connectors available on the market. Its standardized design greatly simplifies circuit board design and component replacement, while enhancing connector versatility and flexibility.

This product features a through-hole package with a 180° vertical pin configuration, which not only facilitates easy PCB soldering but also allows engineers to quickly assemble and maintain devices. It is widely used in prototyping, circuit testing, and production, significantly reducing manufacturing and debugging time.

11.5mm Extended Pins for Secure Depth and Stability

One of the most notable features of this pin header is its extended 11.5mm pin length. Compared to the common 5–7mm pins, this extended length greatly enhances insertion depth and contact area, improving the mechanical stability of connections. This feature is especially important in scenarios with multi-layer PCBs, differing board heights, or cross-board structures.

For example, in industrial equipment or high-power modules, longer pins can penetrate thick PCBs to allow for deep soldering, ensuring a solid connection. This effectively prevents issues such as cold solder joints, open circuits, or poor contact caused by vibration—providing a solid foundation for the long-term stability of the device.

Superior Electrical Performance for Stable Power and Signal Transmission

As a high-quality pin header, the KH-2.54PH180-1X30P-L11.5 also delivers excellent electrical performance:

Rated current: 1.5A – suitable for various signal transmission and low-power supply needs

Insulation resistance: ≥1000MΩ – effectively prevents signal crosstalk or short circuits between pins in high-density applications, maintaining signal integrity

Contact resistance: ≤20mΩ – ensures minimal energy loss during high-speed data or frequency transmission

Dielectric withstand voltage: AC 500V – capable of handling voltage spikes, maintaining stability in fluctuating power grids or special environments

It also features a wide operating temperature range of -40°C to +105°C, making it suitable not only for standard electronics but also for demanding industrial environments with extreme temperature variations—such as outdoor communication systems, automotive electronics, and drone components.

Industrial-Grade Build for Enhanced Usability and Assembly Efficiency

The KH-2.54PH180-1X30P-L11.5 pin header uses high-strength engineering plastic for the insulating body, with a plastic height of 2.5mm to ensure firm pin support and optimized PCB pad alignment. This improves soldering strength and positioning accuracy. The pins are made of high-quality copper and finished with tin or gold plating to enhance oxidation resistance, conductivity, and long-term performance.

The product is packaged in bags for easy sorting and on-demand use. This makes it well-suited for both automatic insertion lines and manual soldering operations in batch production. Each unit weighs only 1.7g, making it lightweight and compact—ideal for high-density PCB layouts and compact product designs.

Versatile Applications with Strong Adaptability

Whether used for I/O expansion and power connections in industrial control boards, or for sensor modules, driver control boards, and LED driver circuits in smart home products, the KH-2.54PH180-1X30P-L11.5 demonstrates outstanding adaptability.

For instance, in embedded development boards and expansion module connections, this long-pin header supports easy signal bridging and temporary debugging without the need for repetitive soldering. It is also widely adopted in maker DIY projects and academic research due to its standardized interface and easy installation—perfect for use with platforms like Arduino and Raspberry Pi.
