Core Features of the KH-1.27PH90-2X10P-L10.5 Pin Header
The Kinghelm KH-1.27PH90-2X10P-L10.5 pin header reveals its strengths right in its model name. “KH” represents the Kinghelm brand; “1.27” indicates the standard pitch of 1.27mm, allowing more pins to fit into limited space for high-density electrical connections. “PH90” shows that the pin header has a 90-degree right-angle design, which not only saves space on the PCB but also enhances installation flexibility, making it adaptable to complex environments. “2X10P” means it has two rows of 10 pins each, for a total of 20 pins, perfectly meeting the needs of high-density connections. “L10.5” refers to a pin length of 10.5mm, carefully designed to ensure stable and reliable connections.

Remarkable Advantages of the KH-1.27PH90-2X10P-L10.5 Pin Header

High-Density Connection to Save Space
As electronic devices become increasingly compact and integrated, space has become a valuable resource. With its standard 1.27mm pitch, the KH-1.27PH90-2X10P-L10.5 pin header accommodates more pins within limited space, achieving high-density electrical connections. This design not only maximizes PCB utilization but also strongly supports device miniaturization and lightweight design.

Right-Angle Design for Flexible Installation
Traditional straight pin headers often face limitations in circuit board layout and installation space. The KH-1.27PH90-2X10P-L10.5 pin header adopts a right-angle (90-degree) design, enabling it to be inserted sideways into the PCB. This saves valuable installation space and greatly improves installation flexibility, making it suitable for complex environments such as narrow spaces and curved circuit boards.

Stable Connection for Reliable Transmission
The length of the pins directly affects connection stability and reliability. The KH-1.27PH90-2X10P-L10.5 features a pin length of 10.5mm, precisely calculated and optimized to ensure full contact between the pins and the PCB while avoiding issues like poor contact or short circuits due to excessive length. With a rated current of 1A, 4mm pin needle length, and 1mm insulator height, these parameters together ensure stable and reliable signal transmission.

Wide Temperature Range for Steady Performance
Electronic devices often generate heat during operation, raising internal temperatures. If the working temperature range of a pin header is too narrow, it can lead to performance degradation or damage. The KH-1.27PH90-2X10P-L10.5 pin header operates within a temperature range of -40°C to +105°C, allowing it to perform steadily in harsh environments and supporting long-term reliable operation of electronic equipment.

Lightweight Design for Enhanced Portability
Lightweight design is now a trend in modern electronics. The KH-1.27PH90-2X10P-L10.5 pin header has a gross weight of only 0.398 grams. This lightweight design reduces the overall weight of the device and enhances portability. At the same time, it helps lower power consumption and transport costs, bringing real economic benefits to both manufacturers and users.

Application Scenarios of KH-1.27PH90-2X10P-L10.5
With its excellent performance and unique design advantages, the KH-1.27PH90-2X10P-L10.5 pin header is widely used in many fields. For example, in communication equipment, it ensures signal transmission and power supply between circuit boards; in computers and peripherals, it connects critical components such as motherboards, graphics cards, and memory; in industrial control systems, it facilitates electrical connections between internal modules. Additionally, it finds extensive use in automotive electronics, medical equipment, aerospace, and other fields, meeting the demands of high-density connections.
