D-Sub Connectors

D-Sub connectors are a type of electrical connector that comes in a variety of different contacts, genders, sizes, types, and voltage ratings. The D-Sub connector family includes the DB-9, DB-15, and DB-25, as well as many other uncommon sizes. The contact and shell materials are typically composed of copper alloys, such as phosphor bronze and brass.

1689789 Application Fields and Working Principle

D-Sub connectors are widely used in computer equipment, networking, medical, industrial, consumer devices, and telecommunications applications. These connectors are well-suited for use in the environments such as factory automation, military, computer, AV and consumer electronics.

The working principle of the 1689789 D-Sub connector is easy to understand. It features two parts, the pin and the socket. The inner pin slides into the outer socket, and is held in place by latches on the outside of the socket. The contact of the two parts creates an electrical connection, which can then be used to power the device.

The contact pins of the 1689789 D-Sub connector are typically composed of phosphor bronze or gold. The gold-plated connectors are ideal for high-density applications, as they can provide reliable and consistent connections even in the presence of high-frequency signals. The phosphor bronze contact pins provide better corrosion resistance and are more flexible than gold-plated pins.

In order to provide reliable and consistent electrical connections, the D-Sub connector must provide adequate strain relief for the wires that are connected. This strain relief feature helps ensure that the connections remain secure and intact even in the presence of vibration, shock, and temperature extremes.

The 1689789 D-Sub connector is also available with a variety of different shell sizes. This allows users to choose a connector that is suitable for their application. The shell size also affects the overall size of the connector, which can help reduce the size of the system and make it easier to install and use.
