DBMA-25P-K87-F0 application field and working principle

The DBMA-25P-K87-F0 connector is part of the popular D-Sub and D-Shaped Connectors series. The DBMA-25P-K87-F0 features a 0.100 inches mounting style, is rated up to 500V, and provides a secure connection point for up to 25 pins.ApplicationsDesigned with a versatile metal shell, the DBMA-25P-K87-F0 is suitable for a wide range of applications. It is commonly used in industrial automation, computing, audio video and broadcast, and medical and laboratory equipment. Additionally, the connector is ideal for use in harsh environments due to its robust design and hermetic sealing between pins.PrecautionsDue to both male and female ends having shielding connection points, the connector is usually meant for one-time application. The contacts must be aligned for plugging. When plugging in the female end of the connector, it is important to note that the male pins can only be mounted to the printed circuit board (PCB) with the terminal faces back-to-back.DesignThe DBMA-25P-K87-F0 is composed of a single piece of metal shell, which includes an integrated ground contact. By having the ground contact integrated into the shell, the DBMA-25P-K87-F0 eliminates the need for a separate connector housing or a separate grounding wire.Working PrincipleThe DBMA-25P-K87-F0 uses a two-piece polarized assembly and several pins and sockets. The metal shell provides both shielding and polarization, while the pins provide the electrical connection and the sockets provide the mechanical connection between the DBMA-25P-K87-F0 connector and the PCB.When the DBMA-25P-K87-F0 is connected to a PCB, the pins on the female end of the connector are inserted into the sockets and aligned with the corresponding pins on the motherboard.The metal shell shielding and polarization ensure that the female end of the DBMA-25P-K87-F0 is connected securely.The pins of the male end of the connector are connected to the PCB and secured with screws. The integrated ground contact on the metal shell helps ensure that confirmation of a secure connection is indicated by a mechanical click when the two components are connected together.ConclusionThe DBMA-25P-K87-F0 is a high quality and reliable connector from the D-Sub and D-Shaped Connectors series. With its versatile design and multiple applications, the DBMA-25P-K87-F0 is a great choice for a wide variety of applications. The connector’s robust metal shell, integrated ground contact, and two-piece polarized assembly make it secure, reliable and easy to use. Its integrated ground contact also helps reduce the need for additional components, saving time and cost.
