A PCB header connector is a type of electrical connector that is typically used in printed circuit boards (PCBs) to establish connections with other components or devices. These connectors are designed to provide a secure, stable interface between the PCB and other external elements like cables, wires, or other PCBs. Header connectors are available in both male and female configurations, with pins or sockets that align with corresponding contacts on a matching connector.

One of the primary functions of PCB header connectors is to provide a reliable, stable connection for data and power transmission between circuit boards or between a circuit board and peripheral devices. They are widely used in applications such as power supplies, communication systems, and embedded systems.

PCB header connectors come in various sizes, pin counts, and configurations to accommodate different circuit board designs. The connectors may feature straight or right-angle pins, offering flexibility in how components are arranged within a system. In addition to their versatility, PCB header connectors are known for their durability and ease of use, making them an essential component in modern electronic assembly.

Overall, PCB header connectors serve a critical role in creating robust connections between electronic components, ensuring proper signal and power flow in complex systems.
