1. Structural Features of the KH-2.54PH180-1X10P-L11.5

The Kinghelm KH-2.54PH180-1X10P-L11.5 is a high-quality pin header designed for electronic connections, featuring the internationally standard 2.54mm pitch, ensuring precise mating with the vast majority of PCB connectors or female headers. Its 1x10P single-row layout supports compact circuit designs while enabling stable signal or power transmission.

It adopts a through-hole mounting method for easy assembly, while the 180° pin orientation offers greater flexibility in PCB layout. The pin length is 11.5mm in total, with a 6mm contact pin section, 3mm tail length, and 2.5mm insulator height, making it adaptable to various PCB thicknesses and mounting requirements. The square pin design ensures excellent mechanical strength and high connection reliability during repeated mating cycles.

2. Performance and Durability Advantages

For electronics manufacturers, selecting a high-performance pin header is essential. The KH-2.54PH180-1X10P-L11.5 has a rated current of 3A, sufficient for most low-voltage DC power and signal transmission applications. Its operating temperature range of -40℃ to +105℃ means it can function reliably in environments with wide temperature fluctuations, such as outdoor equipment, industrial environments, and automotive electronics.

In terms of materials, the pin header uses high-quality metal contacts and a high-temperature-resistant housing, ensuring excellent conductivity and long service life. Its black housing not only resists dirt but also makes it easier to identify on production lines, which is especially beneficial for mass manufacturing.

3. Application Scenarios of the Pin Header

The application range of pin headers is extremely broad. Taking the KH-2.54PH180-1X10P-L11.5 as an example, it is well-suited for:

Embedded development boards – Connecting with functional modules.

Test fixtures and adapter boards – Ensuring stable signal transmission.

Power conversion modules – Providing reliable DC connections.

Smart home control boards – Linking sensors to actuators.

Industrial automation systems – Connecting signal acquisition modules to main control boards.

Automotive electronics – Serving as OBD diagnostic interfaces or as bridges for power and signal in multifunctional modules.

In devices requiring frequent plugging/unplugging, maintenance, or upgrades, pin headers provide a reusable connection method, significantly reducing maintenance costs.

4. How to Select the Right Pin Header

When selecting a pin header, consider:

Pitch – Common options include 2.54mm, 1.27mm, and 2.0mm; pitch determines compatibility with female headers.

Number of rows & pins – Choose single-row, dual-row, or multi-row structures based on signal channel requirements, matching the correct number of pins.

Mounting type – Through-hole, right-angle, or SMT types affect PCB layout and assembly methods.

Mechanical strength & material – Square pins offer higher mechanical strength, suitable for frequent mating applications.

Electrical performance – Ensure rated current and temperature range meet application requirements.

The KH-2.54PH180-1X10P-L11.5 offers balanced, high-level performance in all these aspects, making it a versatile, cost-effective choice.
