D-sub connectors, short for D-subminiature connectors, are distinctive D-shaped metal connectors used primarily in computing and telecommunications. Known for their robust and reliable design, they feature a series of pins or sockets arranged in parallel rows within the D-shaped metal shield. This design ensures correct orientation and provides protection against electromagnetic interference. Common types include DB-25 and DE-9 connectors, used for various applications such as serial and parallel ports, video output, and game controllers. While their usage has declined with newer technologies, D-sub connectors are still valued in certain applications for their durability and reliability.
