D-Sub Connectors

D-sub connectors are multi-pin electrical connectors widely used in many electronic devices, including cable assemblies, networking equipment, computing peripherals, and data communications. They come in many sizes and shapes to meet various electrical requirements. The most common type of D-sub connector is the DBMO25S400, which is a 25-pin mini-D-sub connector commonly used in electronics and computer peripherals. This article will discuss the applications and working principle of the DBMO25S400.

Application Field

The DBMO25S400 D-sub connector is a miniature version of a more traditional DB25 connector and is used in a variety of electronics and computer peripherals. It is most commonly used as an interface connector to connect external devices, such as joysticks, printers, and scanners, to PCs and other digital devices. It is also used to connect cables between Ethernet components, such as routers, switches, and hubs. Additionally, they are used to connect RS-232 links, linking a serial port to a terminal, modem, or other serial device. Furthermore, they are found in serial and parallel port expansion cards, providing several additional serial ports or printer ports.

Working Principle

The DBMO25S400 D-sub connector consists of two parts: the male connector, which has 25 pins arranged in two rows, and the female connector, which has 25 receptacles arranged in two rows. These pins and receptacles are made from gold-clad palladium over nickel plated brass. The pins and receptacles are designed to fit together snugly, ensuring reliable electrical contact and low resistance. The pins and receptacles can be connected to the device’s circuit board through soldering. The connector also features a screw locking mechanism when two connectors are connected, ensuring a strong, secure connection between the two. The connector is designed for a variety of circuit boards, and comes with mounting hardware for easy installation.

Conclusion

The DBMO25S400 D-sub connector is a miniature version of the classic DB25 connector, designed for a variety of applications, such as connecting external devices to PCs, connecting Ethernet components, and connecting RS-232 links. It consists of two parts: the male connector with 25 pins, and the female connector with 25 receptacles. It features a screw locking mechanism and gold-clad palladium over nickel plated brass for reliable electrical connections. It also comes with mounting hardware for easy installation. In this way, the DBMO25S400 is a highly reliable and versatile connector.
