High Density D sub Connectors offer standard D-subminiature (D-sub) connectors and cable assemblies, including common types like DB/HDB/DR/HDR/DP/HDP. A defining feature is the D-shaped metal shell, which provides guidance and electromagnetic shielding, alongside high interface versatility. Their advantage is offering a rugged, cost-effective universal connection solution for computers, industrial controls, and communication devices, widely used in classic standard interfaces such as RS-232, VGA, and parallel ports. Key parameters include pin count, contact gender (pin or socket), shell size, shielding method, and the presence of screw-lock or latch-lock features.
