What Is a D-Sub Adapter?

A D-sub, or subminiature connector, is a type of connection found on computers and other electronic devices. The connection's D-shape design shows the orientation of the plug, a design meant to facilitate access. The size of the D-sub depends on the number of connectors inside the cable. As of the date of publication, D-sub connectors have two to four rows and between nine and 78 positions. Standard and high-density D-sub connectors also have different arrangements and require the use of adapters to change the connection on a cable.

Gender Adapters

The D-sub gender adapter changes a D-sub connection. If you have a mismatched D-Sub connector, a gender adapter is an inexpensive method for resolving the incompatibility problem without changing the hardware. D-sub gender adapters come in virtually every size and configuration. Additionally, for custom applications that use a D-sub connection with a custom configuration, you can use a D-sub kit to configure the plug for use with a gender adapter.

Slim Line Adapters and L-Shape

If your workspace is limited, you can purchase a D-sub adapter designed to work in a small space. Slim line adapters connect to D-sub cables and save space while continuing to provide a reliable connection. L-shape or 90-degree connectors allow you to connect a D-sub cable at an angle which also saves space.

Socket Savers and Capacitive Adapters

If you frequently plug and unplug a D-sub cable, you could wear out the connectors. Worn-out hardware ports require expensive repairs. A socket saver adapter can protect the ports from normal wear and tear. Capacitive adapters allow you to retrofit older D-sub connections, which protects them from electromagnetic and radio frequency interference.

Advantages of D-Sub

D-sub connections offer security by using a lock-down, mating mechanism. Although computers and electronic devices use USB and HDMI connections more frequently than D-sub connections, you can sever USB and HDMI connections by slightly tugging on the cable. D-sub connections, on the other hand, have a tighter connection to the port and do not disconnect under accidental pressure. Additionally, you can configure D-sub connections for a variety of applications including communication, networking and game controlling.
