Introduction to Rectangular Connectors - Headers, Receptacles, Female Sockets

The rectangular connector is an important type of electrical connector for many applications. It includes headers, receptacles, and female sockets. The MDF7-20D-2.54DSA(55) is a specific type of rectangular connector used in a variety of applications.

MDF7-20D-2.54DSA(55) Application Field and Working Principle

Rectangular connectors are used in a variety of electronic applications, including communications, audio-visual systems, robotics, and industrial control. The MDF7-20D-2.54DSA(55) is an angular-style connector that is a header extension. This type of connector is particularly beneficial in situations where space or panel depth is limited.The MDF7-20D-2.54DSA(55) is designed for mounting on panel fronts, and is commonly used in electrical and electronic equipment, such as instrumentation, sensing, and other measuring systems. It is made from a combination of reliable materials, including polyamide insulation and brass electrical contacts, which are designed to last for a long period of time.The MDF7-20D-2.54DSA(55) has two rows of double-row contacts positioned perpendicular to a flat panel. The first row of contacts are contact pads that extend through the panel, while the other row of contacts are head pins that are soldered to the sides of the panel. The header pins are secured into place through the use of a locking device, such as a wire insert, that ensures a secure connection.When the connector is assembled, each contact pad is connected to a respective head pin. Electrical signals can be sent through the connector between various components inside the device, such as embedded microprocessors, programmable logic control systems, sensors, and even power supplies. Moreover, its pins are arranged in a "D" pattern that makes it easier to differentiate between the various pins when making connections.

Conclusion

The MDF7-20D-2.54DSA (55) is a type of rectangular connector used in a variety of applications. It is designed for mounting on panel fronts, and is made from a combination of reliable materials that are designed to last for a long time. Moreover, its unique D pattern of head pins ensures that electrical signals can be sent through the connector between various components inside the device. It is a versatile and reliable connector, perfect for use in a variety of different applications.
