Pin Header | 2mm Pin Header

One of the most critical specifications in a pin header is its pitch—the center-to-center distance between adjacent pins. Common pitch sizes include 2.54mm, 2.00mm, 1.27mm, and 1.00mm, each suited for different applications. A larger pitch such as 2.54mm is often used in hobbyist or prototyping environments, where manual insertion and visibility are important. Smaller pitches allow for higher-density circuit designs, saving valuable PCB space and enabling miniaturization. However, reduced pitch sizes also demand more precise manufacturing to avoid solder bridging or signal interference. The pitch of a pin header must match that of the mating connector or PCB footprint to ensure proper connectivity. Therefore, selecting the appropriate pin header pitch is essential not only for mechanical compatibility but also for maintaining signal clarity, especially in analog or high-frequency circuits.

In high-speed electronic applications, the quality and construction of the pin header can significantly influence signal integrity. Low-quality materials or improper plating may introduce noise, resistance, or cross-talk that degrade the circuit’s performance. High-quality pin headers often feature gold-plated contacts, which enhance conductivity and prevent oxidation, ensuring long-term reliable operation. The choice of pin header housing material also affects temperature resistance and mechanical durability, particularly in industrial or automotive environments. Signal-sensitive circuits such as USB, HDMI, or SPI interfaces require precisely manufactured pin headers with controlled impedance and minimal variation in contact resistance. As more devices adopt high-frequency digital signals, manufacturers are increasingly turning to precision-engineered pin headers to maintain performance standards. Choosing certified, high-reliability pin headers is essential when designing for critical systems like medical devices, aerospace electronics, or high-speed communication modules.

Pin header connectors are essential components used to establish secure and consistent board-to-board or board-to-cable connections in electronic circuits. Typically made of rows of pins aligned on a plastic base, pin headers are designed for easy insertion into mating connectors such as female headers or IDC sockets. Their simplicity, low cost, and adaptability make them widely used across consumer electronics, industrial devices, and embedded systems. A pin header can support multiple pitches (commonly 2.54mm), configurations (single, double, or triple row), and orientations (straight or right angle). Their versatility allows engineers to efficiently design PCBs that require modularity or easy access to test points. As a result, pin header solutions play a crucial role in the compact design of microcontroller boards, power supply modules, and communication interfaces.

Right-angle pin header connectors are specifically designed to provide a horizontal mating interface, which helps save vertical space in compact or low-profile electronic devices. Instead of connecting cables or daughterboards vertically, right-angle pin headers allow connections to be made parallel to the board surface. This layout is ideal for applications like networking equipment, automotive modules, or handheld devices where internal space is limited. Right-angle pin headers are available in both single-row and multi-row versions, with options for SMT or through-hole mounting. Their structure also offers mechanical strength, as the lateral force from the cable or board is better distributed. Using right-angle pin header connectors is a smart design choice when space efficiency, accessibility, and signal routing flexibility are important.
