Kinghelm Pin Header KH-2.54PH180-1X19P-L11.5: The Core Precision Component for Stable Connections

In the world of precision interconnections for electronic devices, pin headers may seem inconspicuous, yet they are like the “joints” of a PCB, responsible for carrying signals and power. When faced with complex circuit layouts and demanding environmental requirements, how can you choose a connector that is both reliable and well-engineered? The Kinghelm KH-2.54PH180-1X19P-L11.5 straight pin header is designed precisely to address this need for a stable, high-quality interconnection solution.

1. Precision Design – Laying a Reliable Foundation

The key advantage of the Kinghelm KH-2.54PH180-1X19P-L11.5 lies in its 2.54mm standard pitch design. This pitch is widely compatible with most PCB design software libraries and standard sockets, offering engineers exceptional design flexibility and eliminating compatibility concerns.
Its 1x19P single-row straight-through structure, paired with a unique 180° bent pin configuration, allows efficient layout even in space-constrained PCB environments—ideal for both vertical and parallel board-to-board connections.
The precisely optimized L11.5mm pin length provides sufficient mechanical support while maintaining a compact footprint, meeting diverse layout requirements.

2. Outstanding Performance – Unfazed by Harsh Conditions

This pin header is not only about looks—it delivers impressive technical performance:

l High current capacity: Rated up to 3A, easily handling power delivery and signal transmission for low-to-medium power modules, ensuring stable device operation.

l Robust mechanical structure: Featuring square pins, which offer greater bending resistance and retention force compared to round pins. Together with a 6mm mating pin length, it ensures ample contact area and reliable connections.

l Wide temperature range: Operates flawlessly from -40°C to +105°C, making it suitable for industrial automation, outdoor devices, automotive electronics, and other environments with extreme temperature fluctuations.

l Precision dimensional control: The 2.5mm insulator height and 3mm solder pin length are precisely calculated to ensure solid solder joints (adequate solder depth) while preventing excessive pin length that could cause short circuits.

3. Wide Application – Powering Diverse Scenarios

Thanks to its standardized specifications and high reliability, the Kinghelm KH-2.54PH180-1X19P-L11.5 is an ideal choice for multiple sectors:

l Industrial control: PLC modules, sensor interfaces, motor drivers, and other equipment requiring stable signal connections.

l Telecommunications equipment: Internal data and power interconnects for routers, switches, and network boards.

l Instrumentation: Precision signal transmission in test & measurement devices and data acquisition cards.

l Medical electronics: Internal connections in monitoring equipment where durability and reliability are paramount.

l Consumer electronics: Smart home controllers, development boards (such as Arduino with matching female headers), and more.

4. Professional selection – Guaranteed Quality

When selecting foundational connectors like pin headers, brand reputation and strict specifications are both critical. As a recognized industry brand, Kinghelm ensures each KH-2.54PH180 series product meets strict quality control standards, guaranteeing precise parameters and consistent performance.
Engineers should focus on key parameters when selecting: pitch (2.54mm), row/pin count (1x19P), mounting type (through-hole), pin type (square), current/voltage requirements (3A), operating temperature (-40°C to +105°C), and mating dimensions (L11.5mm length, 2.5mm insulator height, etc.) to ensure perfect compatibility with mating sockets and the application environment.
