Rectangular Connectors - Housings

Rectangular connector housings come in various forms, shapes and sizes. They can help to provide protection for electronic parts and components while also providing an electrical connection. J21SF-04V-KY housing is a type of rectangular connector that provides an excellent choice for applications requiring single-pair shielded connections.

J21SF-04V-KY connector

The J21SF-04V-KY housing is a single-pair shielded connector designed to protect against EMI/RFI, dust, water splashes, and other external contaminants. It is constructed with a heavy duty die-cast alloy shell and integrated terminal board and has a double-layer shielded cover designed to reduce interference. The housing has a proven service life of more than 10,000 mating cycles and is compatible with standard 2.54mm pitch connectors. The self-latching locks are designed to ensure reliable mechanical connection and consistent signal integrity. The integrated strain relief provides additional protection against lead breakage and contact damage due to flexing of the cables.

Applications

The J21SF-04V-KY connector is a great choice for applications where reliable single-pair shielded connections are needed in a robust and dustproof housing. These housings are well-suited for industrial automation and factory automation applications requiring a shielded connection. They can also be used in applications such as medical device and transportation equipment, where waterproof and dustproof connection is necessary.

Working Principle

This type of housing connector works by providing an electrical connection between two components. The signal between the two components is protected by the double-layer shielded structure from interference and noise caused by EMI/RFI or other external sources. The self-latching secure locks keep each pair of connections firmly in place, ensuring reliable mechanical connection and consistent signal integrity. The die-cast alloy shell provides additional protection from dust and water splashes, while the integrated terminal board helps to reduce wiring complexity.
