D-Sub ConnectorsD-Sub connectors, as the name implies, are connectors in a “D” shape with two distinct sides. They’re found on a variety of devices and machines such as computers, peripherals, data processing equipment, audio/video devices, networking and telecommunications equipment, and more. This type of connector is designed to be durable, cost effective, and secure.The 747839-4 is a type of D-Sub connector primarily used in industrial applications. Their applications include use in scientific research, medical equipment and machines, and manufacturing plants. With its precisely define size, the 747839-4 can be adapted to a variety of uses and distances from the connector.D-Sub connectors like the 747839-4 are designed to have precise mating dimensions between the male and female components helping to ensure a secure connection. The 747839-4 features two opposing “D” shaped shells with two cut out into each face of the shell. Each shell has between two and eight pins. The pins are arranged in a specific pattern that fits into the resistance tabs of the female connector. This creates a secure connection and helps to prevent accidental disconnection.The working principle of the 747839-4 is simple but effective. The two opposing shells slide together while the pins slide into the slots in the female connector. This locks the two parts together and creates a connection between them. The pins make physical contact which allows for the exchange of data. This connection allows for the transfer of data between two devices.While the 747839-4 features two shells, some D-Sub connectors feature three shells. These types of connectors are referred to as three shell connectors and are used in a variety of applications. They feature a center shell that snaps into place, allowing for easy assembly. Three shell connectors tend to have fewer pins than the two shell versions and are slightly more expensive. Overall, the 747839-4 is a type of D-Sub connector. It is designed to be durable and secure, capable of withstanding heavy loads and strain. It also features precise mating dimensions between the male and female components that help create a secure connection for the transfer of data. The working principle of the 747839-4 is quite simple and helps ensure the secure connection of two devices.
