D-Sub Connectors: MDM-25PSM7 Application Field and Working Principle

D-Sub connectors are types of electrical connectors which have a characteristic electrical shield around the pins, and are often used in cables and peripheral devices. This type of connector is named after the distinctive “D” shape of the metal shell enclosure. MDM-25PSM7 is an example of D-sub connector that is used for a variety of applications. It is a mini version of the standard D-sub connectors, coming with a body size of 15.5mm x 31.5mm and a 25-pin configuration.

Applications

MDM-25PSM7 has various applications in different industries. For industrial applications, these connectors are used in automated assembly systems like robots and sensors, while in the medical field, they are used for patient monitoring. In the telecommunications sector, these are used for data transmission in modems and mobile devices. This connector is also used in the automotive industry for vehicle control and navigation systems.

Working Principle

MDM-25PSM7 has a metal housing in the form of D-shaped metal shielding plates that are placed around a center pin array. The metal shielding is made from aluminum or similar material which acts as a heat dissipater, and the center pin array is made from brass alloy. The contact between the center pin array and the metal shielding plates is secured by crimping.The shield is attached to the metal housing, and this forms an electrical ground shield that is designed to reduce and prevent electrical noise. The pins connect to the mating device, and the contact between the pins and their mating devices is achieved by inserting the pins into the molex connector. This contact is necessary to provide electrical current to the connection. The connectors also feature anti-corrosion protection, which provides improved resistance and protection against harmful environmental influences such as moisture. Furthermore, the connectors come with a dust-proof cap that is designed to protect the pins from dust and other environmental hazards.

Conclusion

MDM-25PSM7 is an example of D-sub connector that is used for a variety of industrial applications. It is a mini version of the standard D-sub connectors, coming with a body size of 15.5mm x 31.5mm and a 25-pin configuration. The working principle of this connector includes a metal shield housing, which provides an electrical ground shield, as well as a center pin array made from brass alloy. Additionally, features such as the anti-corrosion protection and dust proof caps make the MDM-25PSM7 a reliable connector for industrial and medical applications.
