D-Sub Connectors

A D-Sub Connector is a kind of electrical connector that includes a number of pins or contacts in two rows. The DD-50S-RR is one of the many D-Sub Connector types that is most commonly used for various data, video and power transfer systems. Each type of D-Sub Connector is identified by the number of pins and this one contains 50 pins, in a row-row configuration. Let’s look at the applications field and working principle of the DD-50S-RR.

Application field of DD-50S-RR

The DD-50S-RR is usually found in various audio applications such as mixing consoles, CD and DVD players, music studio equipment and other audio systems, such as hifi systems. It is also used in video applications like video games, LCD monitors, digital cameras and other digital video TV products.

Another application field for the DD-50S-RR is computer based and mainly includes computers, laptop computers, printed circuit boards (PCBs) or any other related electrical equipment.

It is also increasingly being used in car audio, electrical medical devices, mechatronics and industrial automation systems.

Working principle of DD-50S-RR

The DD-50S-RR has a rectangular die-cast housing with two rows of contacts each side. In the center of the DD-50S-RR there is an insulation divider that has been contact loaded in an accordion-style, this insures uniform contact force along the entire contact block. It also has a mechanical stop that prevents the contacts from being damaged by being over-tensioned. When connecting two DD-50S-RRs together you simply insert the contacts on one side into the contacts on the other side, then twist it into place.

The DD-50S-RR is primarily based on an electrical contact design that consists of a metal alloy base contact that has been gold gold plated. This design delivers a very high level of performance and durability, the gold plating improves contact life expectancy and the metal alloy base contact makes it resistant to corrosion.

The DD-50S-RR uses a specialized three-piece latching system where two large arms secure the contact block in place at the center. The latching system can be released and locked manually.

Conclusion

The DD-50S-RR D-Sub Connector is a reliable and durable solution for transferring audio, video, data and power applications. It has a simple and efficient three-piece latching system and a metal alloy base contact with gold plating for improved contact life expectancy and resistance to corrosion. The DD-50S-RR is widely used in various audio, visual, computer and industrial applications.
