A 2.5mm Pitch Connector refers to an electrical connector where the distance between the center of one pin to the center of the adjacent pin is 2.5 millimeters. They are commonly used in various electronic applications, such as in printed circuit boards (PCBs), where they facilitate the connection of different components or devices. The choice of connectors depends on the requirements of the electronic system, including considerations for signal integrity, power delivery, and mechanical constraints. This pitch measurement is a crucial specification for connectors as it determines the spacing between electrical contacts. 2.5mm Pitch Connector come in various types, including headers, sockets, and cable connectors.
