D-sub connectors once played a more dominant role in electronics. They were easy to use and provided a gratifying physically secure connection. However, times have changed and so has the technology on which the world relies. With a heavier reliance on USB & HDMI connections being more widely used, questions abound about the viability of d-sub connectors in the years to come.
In terms of questions, however, the most common query about d-sub connectors has to do with the name. D-sub connectors are a type of electrical connector whose name is derived from the shape of the metal shield that covers the rows of pins/sockets in the connector (think a capital D shape). Variations in the type of d-sub connector can be identified by the part numbering based on the original system created. These letters and numbers allowed for quick identification of connector size, as well as pin/socket number. However, as the technology changed over time, identification & labeling systems grew more complex.
In certain applications, d-sub connectors are the ideal connection choice for quite a number of items. Older machinery that is still fully operational may not be able to support newer technology. Replacing everything (in terms of physical infrastructure) can be quite expensive. It makes more sense to keep using d-sub connectors, albeit better quality versions.
D-sub connectors can be found in a variety of industries, including but not limited to:

  • Telecommunications & Data Transmission
  • Security for Military Applications
  • VGA connectors in Gaming
  • Connecting Computers to Printers & Power Supply Units
  • Robotics
  • Aerospace
    It is worth mentioning that d-sub connectors find their place in areas where visibility to the masses is quite low. Their reliability & low cost makes them perfect for use in DIY electronics projects, wide spectrum of media, and mobile applications that require strength & durability of components during transport and/or use.
    There is no denying that the world has a major reliance on wireless technology. In fact, round-the-clock wireless connectivity has changed the world, for better or worse. As such, the idea of maintaining any kind of attachment to a physical interconnect solution like a d-sub connector in the face of wireless tech may seem a bit odd. However, it is important to keep in mind that even the most powerful wireless systems rely on a dependable, reliable, near bullet-proof hardwired infrastructure to keep it up & running. At the heart of these infrastructures, it is not surprising to see d-sub connectors doing the same work they have been doing since their introduction in 1952.
