This model adopts the standard 2.54mm pitch design, fully compatible with most PCB layouts and mating connector standards on the market, ensuring quick matching and replacement during product design. Its 1x3P (single-row, three-pin) configuration is ideal for low-pin-count signal transmission or power output, completing efficient connections within a minimal footprint. The pins feature a 90° right-angle design, making them perfect for circuit boards requiring low height or side-entry connections. This helps save internal space, optimize cable routing, and reduce assembly interference.

The KH-2.54PH90-1X3P-L13.8 has an overall length of 13.8mm, pin length of 6mm, and plastic height of 2.5mm. With strictly controlled tolerances, it ensures consistent and stable connections in mass production. Made from high-quality metal pins, it supports a rated current of 3A, meeting most small to medium power signal and power transmission needs. Its operating temperature range is -40°C to +105°C, meaning it can perform reliably in both indoor consumer electronics and outdoor industrial control systems without contact issues or performance degradation due to temperature changes.

In terms of materials and craftsmanship, the pins are made of high-conductivity copper with surface plating for improved corrosion resistance and stable contact performance, preventing oxidation and rust during long-term use. The black high-strength engineering plastic housing offers excellent insulation and maintains its shape during high-temperature soldering, reducing deformation or cracking for a higher soldering success rate.

Application Scenarios:
The KH-2.54PH90-1X3P-L13.8 is highly versatile, fitting seamlessly into various electronic product designs. Examples include:

lAs a signal and power interface between microcontroller development boards, sensor modules, control panels, and expansion boards.

lIn industrial control systems, enabling modular designs where functional boards can be connected via pin headers for easy maintenance and upgrades.

lIn communication devices and automotive control systems, where its right-angle form excels in space-limited or special mounting situations.

When selecting a pin header, factors such as pitch, pin count, mounting style, rated current, operating temperature, and material durability should all be considered. As a high-quality product from Kinghelm, the KH-2.54PH90-1X3P-L13.8 has earned market recognition and user trust thanks to its meticulous design and strict manufacturing processes. For engineers seeking high reliability and cost performance, this pin header is an excellent long-term choice.
