Rectangular Connectors - Headers, Receptacles, Female Sockets

20021321-00028T4LF is a type of rectangular connector, part of the headers, receptacles, and female sockets family. Those kinds of connectors are the most commonly used electrical connectors and are employed in a variety of different applications.

Application Field and Working Principle

The 20021321-00028T4LF is constructed with two main components, the female socket and the male header, that contain pins on the mating sides. The principle of their functionality relies on the two components being securely mated, ensuring reliable electrical continuity. The male header has a series of raised pins and the female socket has a series of mating holes: when the two components are snapped together, the pins easily fit into the female socket’s mating holes, and the connector is then locked in place. This connection provides high protection against strong vibrations and other environmental conditions.

Due to their reliable flexibility and simplistic design, these models of electrical connectors are used in various scenarios, such as domestic and industrial machinery, data acquisition, communication links, and medical devices. The 20021321-00028T4LF, for instance, is ideally used in applications that require a secure connection with a high level of environmental protection to control the power to medium-low current devices.

Moreover, the 20021321-00028T4LF connectors have additional features that make them ideal for certain applications. For instance, the connectors are available in both surface mount (SMT) and through-hole (THT) versions, and they are compliant with numerous standards in the industry, such as UL, CE, and IEC.

In addition, these electrical connectors usually feature polarized housings with keying options, allowing them to be used in systems with multiple connector types. This helps to prevent incorrect mating when any additional pins or connectors are involved.
