Advantages of D-subminiature Connectors


D-sub or D-subminiature connectors are standard electrical connectors. The exciting thing is that their name comes directly from their shape. Their metal shield is D-shaped, and therefore they are called D-sub connectors.

In the beginning, they were the smallest connectors you could use on any computer system. They contain at least two rows of sockets or pins. The metal shield is there to protect the connector and give proper orientation.

Cannon first introduced these connectors in 1952. In the same year, they introduced a whole series of connectors from A to E.

They are mainly used for digital audio recording as well as a multi-channel analog audio recording. The D-sub connectors are widely popular and have many applications.

They can be used for industrial, telecommunication, military, medical, etc., purposes. What are the different types of D-sub connectors?

There are different connection methods when it comes to D-subminiature connectors. They can be vary depending on system circuitry and how the contacts are connected.

One of the biggest advantages of D-sub is that they can be used for locking technology, which is used for keeping the mated position on plugs and sockets.

Furthermore, the D-sub ports offer better resistance to tampering as well as jostling. This is compared to the Thunderbolts, HDMI, and USB ports.

Different numbers of pins/jacks 

As mentioned above, there are different types of D-subs that were introduced to the market A, B, C, D, and E.

These letters represent the number of contacts of each connector’s socket. Nine pined plug with the smallest size is known as the DE-9.

For those that are high density, usually, it is added an “HD” mark to their names. For example, HD D-sub will mean a denser pin arrangement in the shell of the connector.

Duration of the connection 

The third characteristic by which these connectors are divided is the duration of the connection. In brief, there are two basic connection styles. The first one is soldering, which is used in industries where a permanent connection is required.

The second is crimping, and it is mainly used in homes because it offers a temporary connection. How to find the right connector for you?

On the other hand, the d-substandard board mount connector is widely used. For this connector, the name speaks for itself, standard density. The great thing about this product is that it comes to Pin-in-Paste and Press-Fit terminations.

If you want something that has removable crimp contacts, then the best option for you is probably the d-sub cable connector.

This type has different hood options and can have mixed layouts as well as full ones. Additionally, you can choose whether you want an economy or a standard option.
