Card edge connectors are a type of electrical connector that are commonly used to connect circuit boards or cards to a system or a device. Card edge connectors have a long, narrow shape with a series of contact pins or pads along one edge, and are designed to mate with a complementary connector on the circuit board or card.
Card edge connectors are commonly used in a variety of applications, such as computers, telecommunications equipment, and industrial control systems. They are available in different sizes and styles, depending on the specific requirements of the application. Card edge connectors can be used to connect circuit boards or cards that are parallel or perpendicular to the connector, and are often used in conjunction with other types of connectors, such as backplane connectors or ribbon cable connectors, to provide a complete connectivity solution.
