First, the KH-2.54PH180-1X6P-L11.5 features a single row structure with a total of 6 pins and a standard 2.54mm pitch. This pitch is not only one of the most widely used specifications in the industry but also provides excellent versatility and compatibility, allowing easy integration with various wire-to-board connectors or female headers without concerns about assembly misfits. It is especially suitable for circuit board designs requiring multiple signal channels, greatly simplifying engineers’ selection and layout work during the design phase.

The product uses through-hole (THT) mounting, compatible with mature processes such as wave soldering. This significantly improves production efficiency while ensuring firm soldering and long-term reliability. Compared with surface-mount (SMT) pin headers, through-hole structures are more advantageous in scenarios demanding higher mechanical strength or frequent plugging and unplugging, as they are less prone to false soldering or loosening caused by vibration or impact. This makes them especially suitable for automotive electronics, industrial control equipment, and portable instruments where stability is critical.

From the pin design perspective, this model uses square pins instead of round pins. Square pins provide a larger contact area, which helps reduce contact resistance, resulting in better performance for both signal transmission and current carrying. The KH-2.54PH180-1X6P-L11.5 supports a rated current of up to 3A—sufficient to meet the power needs of medium-power devices. Whether for motor drivers, small power modules, or communication interfaces, it ensures stable current delivery, reducing the risk of overheating or insufficient current.

Moreover, the product’s dimensions are thoughtfully designed to balance performance and structure:

lMating pin length of 6mm ensures reliable contact;

lSolder tail length of 3mm facilitates secure mounting to the PCB;

lPlastic height of just 2.5mm helps minimize the impact on the overall device thickness, making it particularly suitable for compact product designs;

lWith a weight of only 0.4 grams, it further supports lightweight product layouts.

In terms of durability, the KH-2.54PH180-1X6P-L11.5 operates reliably within a temperature range of -40℃ to +105℃, undeterred by rapid temperature changes, thermal shocks, or harsh environments. This is especially valuable for outdoor devices, automotive electronics, or industrial automation equipment that must function stably over long periods under complex environmental conditions, significantly improving product reliability and lifespan.

For packaging and shipping, the product is supplied in bags, which not only facilitates storage and transportation but also helps automated production lines quickly sort and handle parts—lowering production costs. The classic black plastic body offers a clean, professional look, supports quick visual identification, and matches most PCB colors to maintain a cohesive overall design.

As a well-known brand in the connector industry, Kinghelm insists on strict quality standards throughout product R&D and manufacturing. The KH-2.54PH180-1X6P-L11.5 embodies this philosophy: it offers a larger contact area and higher current capacity, while thoughtful structural design delivers greater mechanical strength and durability. Compared to ordinary pin headers, this model is especially suited for applications that demand greater stability, higher current handling, and operation in harsh environments.

Specifically, it is highly suitable for:

1. Industrial automation equipment – maintaining stable connections under high vibration;

2. Automotive electronics and new energy systems – tolerating a wide temperature range and higher currents;

3. Smart hardware and IoT terminals – where lightweight and compact layouts are key;

4. Communication and security equipment – where signal stability is critical;

5. Small power modules – requiring reliable power supply and durable interfaces.
