D-Sub Connectors

D-sub connectors, also known as DD connector’s, are a family of electrical connectors used in a variety of applications. They are a popular choice for many industrial applications as they are non-proprietary, have a moderately high power rating, can accommodate more pins than circular connectors, and are relatively inexpensive. Common applications for D-subs include printer/controller circuits, video/audio signal connections, as well as many others.

3-1634225-2 Application Field and Working Principle

The 3-1634225-2 D-Sub connector is sized for both square and rectangular pins and is recommended for use in electronic applications, patch panels, computers, and enclosures. It is also backward compatible with any older applications or enclosures that use 2-7621945-5 style connectors. The 3-1634225-2 D-Sub connector is rated at 27V for 4A and 1A for 50V depending on its configuration, and has a moderate contact resistance rating of 20mΩ max. The design features a plastic housing with two latching mechanisms that secure the two connectors together, ensuring reliable continuity.

To assembly the 3-1634225-2 D-Sub connectors, the user only need to insert the mating pins into the openings on each connector. The two latching mechanisms then secure the two halves together. The pins of the male connector are arranged in two rows, with the female connector possessing four rows. Increasing the number of contacts between the two connectors, greatly increases the signal integrity of the circuit.

The insulation of the 3-1634225-2 D-Sub connectors is designed to maintain excellent dielectric strength of 5000Vac at 250Vdc for 1 minute. This ensures a high level of protection against high-voltage transients and electrical surges, which could potentially damage the circuit or cause connection failure. Additionally, the 3-1634225-2 connector provides great anti-corrosive protection from acidic contaminants.
