Connectors - Headers, Male Pins, MDF7-18P-2.54DSA(55)

Connectors are essential components of just about any electrical application. The particular type of connector used depends on the specific requirements of each individual application. One such type of connector is the MDF7-18P-2.54DSA(55), which is a rectangular connector, male pin header. The following is an overview of the application field and working principle that this particular type of connector provides.

Application Field

The MDF7-18P-2.54DSA(55) is primarily used in computer and mobile computing applications, particularly for connecting and exchanging data between devices. This connector is primarily used in internal applications for a PCB, such as for signal transmission, power current, and connection to a laptop or mobile device. This particular connector is rated for 250V/2A and designed for a maximum 4500 mating cycles.

The MDF7-18P-2.54DSA(55) is reliable enough to handle high power and data requirements, meaning it is capable of being used effectively in any moderately heavy computing and electronic application. As a result, this connector is often used in routers, modems, motherboards, and for various gaming consoles. Some examples of its specific application include USB, SATA, SATA II, SATA III, LVDS, Parallel ATA, and even RGB.

Working Principle

The MDF7-18P-2.54DSA(55) connector uses an integrated design principles, with long-term reliability in mind. These principles include the use of gold-plated pin contacts, friction-lock mechanisms, and anti-vibration pins. The connector is designed to have a high retention force, which prevents the connector from being accidentally pulled apart. It also provides a smooth transition between power and signal contacts.

The MDF7-18P-2.54DSA(55) also uses a self-locking mechanism to keep the connector firmly in place and prevent loosening during use. This pin header utilizes a two-part configuration, with a plug and socket. The plug portion contains the male pins which are gold-plated, making them corrosion-resistant, and able to provide reliable and consistent signal transmission. The socket portion houses the female contacts, and the two parts are connected with a lock, to ensure that the connection is secure.

The MDF7-18P-2.54DSA(55) is also designed to withstand extremely high vibration and shock. Its design allows for vibration testing up to 14G and shock testing up to 20G. The connector also has been designed with a low contact resistance threshold of 250K, and low contact leakage current to prevent electro-magnetic interference (EMI).

Conclusion

The MDF7-18P-2.54DSA(55) is a rectangular connector, male pin header that is designed for robust and reliable performance. It is primarily used in computer and mobile applications, and provides data transmission and power current. This pin header utilizes a two-part configuration, with a plug and socket. It is designed with gold-plated pins and features a friction-lock and anti-vibration pin mechanism. It is also rated to provide reliable performance at up to 250V/2A, and is designed for a maximum of 4500 mating cycles. The MDF7-18P-2.54DSA(55) provides dependable performance for any moderately heavy computer and electronic application.
