MDF7-21P-2.54DS(55) is a type of rectangular connector - headers, male pins, used in electrical circuits. It is a female 2.54-mm pitch, 21-circuit, shielded header type connector, with a maximum current up to 0.5A. These connectors are common in the electric industry as their size and ease of use make them perfect for many applications.

The MDF7-21P-2.54DS(55) rectangular connectors are made from a nylon UL94V-0 rated material, making them durable and resistant to aging. The contacts are made from gold plated copper alloys, which provide superior electrical conductivity and resistance to corrosion. All contacts are shrouded with a metal protective sheath, which provide further protection from UV light and other environmental hazards.

Their wide range of uses has ensured the MDF7-21P-2.54DS(55) rectangular connector - headers, male pins- is used in all sorts of electrical applications and circuits. From making connections for computer motherboards, appliances, relays, sensors, receivers, switches, electric motors, fans, and many other electrical and electronic items.

Due to their small size and easy to use design, these connectors are also used in consumer products such as audio/video equipment, toys, and consumer electronics. Since they’re so versatile, they have become one of the most popular connectors available and can even be found in the automotive and medical industries.

The working principle of the MDF7-21P-2.54DS (55) connector is straightforward and efficient. The connector consists of two components: a housing and a pin. The body of the connector is designed in such a way that when the pin is inserted, it forms a solid and precise connection with the contacts in the connector housing. The pins are slightly spring-loaded when inserted and they have a friction lock to ensure that the connection is secure and stable.

The pins themselves are designed for high-speed data transfer, which makes them ideal for use in data communications or digital IO applications. They are also a perfect solution for making connections in high density products such as mobile phones, cameras, etc. This is due to their small size, which allows them to be used in tightly-packed circuit boards with limited space.

The MDF7-21P-2.54DS(55) rectangular connector with its high-speed data transfer capabilities, superior electrical conductivity and resistance to corrosion, is an ideal solution for all kinds of electrical circuit designs. Its small size and easy installation make it perfect for use in any type of electrical application. Whether a designer needs a durable, reliable, and compact connector for an industrial application, or simply wants to make a quick connection between devices for a consumer product, the MDF7-21P-2.54DS (55) is the perfect solution.
