DF3EA-2P-2H(51) Connectors, Interconnects

DF3EA-2P-2H(51) is a two position, two row surface mount header connector that is generally referred to as a rectangular connector. It is a type of electrical connector, used to provide a means for connecting electrical wires, cables, and printed circuit boards (PCB).

Applications

The DF3EA-2P-2H(51) is a popular choice as a wire-to-board connector due to its low profile, having only a 2.5mm mounting height. This low profile makes it especially attractive in applications where space is at a premium, such as consumer electronics, automotive, or telecommunications equipment. The connector is also considered suitable for use in harsher environments due to its ability to be plugged and unplugged without the need for soldering.

The connector is also used in a wide variety of computer related applications, such as motherboards, network switches, modems, and other communication systems. Its versatility and low profile greatly reduce the need for bulky connectors for many small form factor applications.

Working Principle

The DF3EA-2P-2H(51) connector’s basic design is composed of a header and a series of pins. The header, which is a rectangular shaped piece of metal, has two rows of holes. Each hole in the header is slightly larger than the diameter of the pins. This difference in size creates a friction fit between the pin and the holes.

When two connectors are mated, the male pin in the first connector inserts into the second connector\'s holes. The friction fit holds the mated connectors together, while having the ability to be easily disengaged when needed. This makes the DF3EA-2P-2H(51) extremely reliable in applications where frequent plugs and unplugging is required.

Due to its compact design and reliable connections, the DF3EA-2P-2H(51) connector is a popular choice for connecting wires that can handle both power and data in low-profile space. It is available in both pre-assembled and unassembled form, for greater flexibility in customizing the connection for various applications.
