Pin Header and Female Header connectors are fundamental board-to-board or wire-to-board interconnect solutions widely used in consumer electronics, industrial controls, and communication equipment. These connectors consist of male pin headers and female sockets, with standard pitch sizes ranging from 0.5mm to 5.08mm to accommodate varying density requirements. Their key advantages include simple construction, cost-effectiveness, and ease of assembly, making them ideal for establishing reliable electrical connections—such as between a main PCB and an expansion board.
