Rectangular Connectors - Headers, Receptacles, Female Sockets

The application field and working principle of 20021321-00042D4LF rectangular connectors are quite extensive, and can be divided into three categories: headers, receptacles, and female sockets.

Headers

The most common application of headers is to provide reliable connections between an integrated circuit and a printed circuit board. They can also be used to connect cables or other wiring components. Headers have two parts, an insulating base and conductive pins. Conductive pins are typically designed to be acceptably mated with the proper mating connector to create an electrical connection.

Receptacles

Receptacles, the mating partner of headers that can mate with them to complete the electrical connection, are also widely used. Receptacles are either mounted onto a printed circuit board or part of a cable assembly. They are cost-effective when compared to headers because they are typically sold in groups of many and connect many individual pins at once.

Female Sockets

Female sockets are designed to accept various pin sizes and offer a way to quickly wire and connect two circuits together. They offer a simple way to connect a circuit to a terminal or another circuit. A secure electrical connection is provided when a rotated key is aligned with a mating pin. Some types of female sockets are designed to be used over and over again and are more reliable than a soldered connection.

To sum up, the application field and working principle of 20021321-00042D4LF rectangular connectors can be divided into three categories: headers, receptacles, and female sockets. Headers make reliable connections between integrated circuits and printed circuit boards, receptacles are the mating partner of headers that create electrical connections, and female sockets are designed to accept various pin sizes and offer quick electrical connections between two circuits.
