D-Sub Connectors

A D-subminiature or D-sub is a common type of electrical connector. They are named for their characteristic D-shaped metal shield. This shield has several mounting holes so it can be fastened to a panel or chassis. Examples of their intended use include computer serial and parallel ports, game ports, and data cable connectors.

5-208866-1 Application Field and Working Principle

The 5-208866-1 is a robust "D" shaped connector for applications ranging from consumer electronics to industrial control. It has a low profile and strain relief that permit a wide range of applications including patch cords, cable assemblies, electromechanical, push-pull latches, Ethernet, high speed digital, coaxial, and audio/video. This connector also features a polyolefin housing, 8 gold plated contacts, and a mounting flange 31.9 mm x 38.8mm for secure mounting.

The working principle of the 5-208866-1 is very simple. It has 8 pins arranged in two rows that form the contact with a receptacle. The two rows are aligned with the inside of the shield to ensure a proper connection. To ensure a secure connection, the pins are held in place by a pin block inside the connector and a planar contact support located inside the receptacle. The pins are also surrounded by a metal shield that provides EMI and RFI shielding. This shield is also designed to ensure proper contact with the receptacle pocket.

The 5-208866-1 also has a secure latching mechanism to keep the connector in place. The latching mechanism has two tabs that latch onto the edges of the receptacle, holding the connector securely in place. This latching mechanism also provides strain relief, which helps protect the contacts from bending or damaging. The latching mechanism also has a self-aligning feature, meaning the connector will always properly align with the receptacle when it is plugged in. This ensures a secure and reliable connection.

In addition to the latching mechanism, the 5-208866-1 also features a silver-plated contact surface, ensuring optimal signal performance and reliability. This contact surface also provides corrosion protection and improved conductivity. The silver plating on the contact surface also ensures that the contact area remains clean, free of oxidation or contamination. The connector also features a tough polyamide housing that resists shock, vibration, and abuse.

Overall, the 5-208866-1 is an excellent choice for applications such as consumer electronics, industrial control, patch cords, cable assemblies, electromechanical, push-pull latches, Ethernet, high speed digital, coaxial, and audio/video. It is reliable, durable, and offers reliable signal performance. This connector is an excellent choice for any application requiring a robust connection.
