PCB header connectors, also known as pin headers, are essential components in the world of electronics. They are used to establish electrical connections between a printed circuit board (PCB) and external devices or other PCBs. These connectors are designed to be robust, reliable, and easy to use, making them a popular choice for a wide range of applications.

There are various types of PCB header connectors, each with specific characteristics to suit different needs. The most common types include:

Straight Header Connectors: These are used when the mating connector is on the same plane as the PCB.

Right-Angle Header Connectors: These are used when the mating connector is perpendicular to the PCB, allowing for a more compact design.

Surface Mount Header Connectors: These are mounted directly onto the surface of the PCB, offering a more streamlined look and reduced height.

The connectors are available in different pitch sizes, with 2.54mm (0.1 inch) being the most common. Other pitches include 1.27mm (0.05 inch) and 1.0mm (0.04 inch), which are used for high-density applications.

PCB header connectors are typically made from materials such as brass, phosphor bronze, or steel, which provide good electrical conductivity and mechanical strength. The pins are often gold-plated to ensure a low-resistance connection and to prevent corrosion.

PCB header connectors are a fundamental part of electronic design, offering a simple and effective way to connect components. Their versatility and reliability make them indispensable in a wide range of applications, from consumer electronics to industrial equipment.
