D-Sub Connectors

D-sub connectors (or D-subminiature connectors) are a type of electrical connector that are widely used in industrial, commercial, and consumer applications. They were initially developed in the 1950s to address the need for more space in larger applications, such as in military applications. Since then, they have been used in a variety of applications, from personal computers to medical instruments. They can be used to connect computers, modems, printers, and other components together. D-sub connectors are available in various sizes, shapes, and configurations depending on the application they are being used for.

787686-1 Application Field and Working Principle

The 787686-1 is a standard 3-pin D-subminiature connector with a 15-pin arrangement. It has a 4-position male-to-female configuration and is used with medium- to large-sized applications. This connector features two male contact pins with a ring ground at the center. This connector is often used to connect a computer to a monitor or a printer, or to link one device to another via a cable.

The working principle of the 787686-1 connector is based upon a magnetic force that is generated when two ferrous metals come in contact with each other. This magnetic force creates an electrical connection between the male contact pins and the female contacts on the other end of the connector. When the female contacts are forced against the male contacts, an electrical connection is formed and the signals or power can pass through the connection. This design allows for a reliable connection and can be used at high speeds with no signal degradation.

This type of connector is made from a variety of materials, including aluminum, stainless steel, copper, and brass. The connector is highly durable and designed to withstand a wide range of temperatures, making it ideal for rugged applications. In addition, the pins of the 787686-1 are gold-plated, which increases their corrosion resistance and allows them to withstand oxidation better than other materials.

The 787686-1 connector is widely used in a variety of applications, including for industrial control and monitoring systems, communications and relays, precision instrumentation, audio/video systems, and computer peripherals. This connector is particularly suitable for rugged applications, since its durable construction and gold-plating can withstand harsh environments. Additionally, the connector is also relatively easy to install and inexpensive, which makes it a popular choice for many applications.
