Combination D-Subminiature connectors are a popular choice for a wide variety of applications, as they offer signal, power, coax, and high voltage contacts mixed within a single connector package. The connectors are available in all six standard D-sub shell sizes and offer a multitude of contact variants. Legacy Combo D connectors use size 20 contacts for signal level connections. However, this practice underutilizes the electrical capabilities of size 20 contacts and limits high density packaging options. Combo D connectors are offered with size 22 high density contacts for use with signal level connections. Also, along with standard size 8 power, coax and high voltage contacts, the company's CBDD series offers size 16 power contacts for low to midrange power applications.
