D-Sub Connectors

Overview

D-Sub connectors, also known as D-subminiature or DB connectors, are devices used to establish electrical connections between circuits, devices, and other systems. The plugs or receptacles of these connectors have distinctive "D" shapes, which give rise to their familiar names. Typically, electrical connection is made by mating the male plug with the female receptacle. D-sub connectors are available in various configurations, like 9STD15SAM99B30X, to suit the precise requirements of the application.

Types

D-sub connectors are available in several types that are differentiated by the number of pins, the layout of pins, or the type of mounting.

Types Based on Pin Configuration

The most common configurations include 9, 15, 25, 37, and 50 pins. Double-density models, like the 9STD15SAM99B30X, provide more contacts in the same amount of space.

Types Based on the Mount Position

D-sub connectors also have various mounting configurations, like right-angle, printed circuit board (PCB), servo, integrated circuit, edge-mounts, plugs and sockets, and straight board-mounts.

Features and Benefits

Durability

D-sub connectors are built to be robust and hard-waring, enabling them to withstand the rigors of regular use. The components of these connectors are often designed with ruggedness in mind, delivering superior product life even in highly challenging environments.

Size

D-sub connectors are normally available in a standard form factor that makes them suitable for applications where space is a constraint. The 9STD15SAM99B30X model, for example, offers a higher contact count in the same amount of space, while other compact types are also available for tight applications.

Versatility

D-sub connectors are particularly suitable for diverse applications containing various types of electrical connections. These are available in different materials, contact ratings, sizes and pin counts, making them applicable across different industries.

Versatile Applications

D-sub connectors are widely deployed in a myriad of applications, like networking, computer, and instrumentation applications. Computer applications are the most common, where the connectors are used to interface peripherals, like the keyboard, mouse, and touchscreen, as well as for connection to the hard drive or handset. In addition to these uses, D-sub connectors are also used for networking, industrial automation, telecommunications, medical, and automotive applications.

9STD15SAM99B30X Application Field and Working Principle

The 9STD15SAM99B30X is a double-density D-sub connector, which offers a higher number of contacts in the same amount of space as a single-density model. It is built with robust materials that offer additional durability and dependable performance. In terms of applications, the 9STD15SAM99B30X is typically used in computer peripherals, networking, industrial automation, telecommunication, medical, and automotive devices, among others.The working principle of the 9STD15SAM99B30X D-sub connector is relatively simple. It involves the use of two interconnecting components: the male plug and the female receptacle. The male plug usually has a set of pins, while the female receptacle has holes within which the plug\'s pins are inserted. The two components are mated together to form a secure connection that enables electrical signals to pass between them.
