IDC 2.54mm RA CONNECTOR IDC Disconnectable Insulation displacement connectors for 1.27mm (.050") pitch ribbon cables (.100") pitch Features ----------------------- * Twin U-slot The twin U-slot is the most important IDC element in Beam B JST's RA connectors. As Slot shown in the figure, wire conductors are connected Beam A Beam supporter between the slots of U-shaped Conductor parallel beams, and the distance between each adjacent pair of beams is Double-leaf contact designed to be one third of the pitch of wire strands. * Two-die processing and selective gold plating Two precision dies are used to blank and form the contacts. After the first die blanks the contacts, they are gold plated at crucial points. Then, the contacts are formed by the second To keep pace with the rapid developments in electronics, internal and external connection systems are naturally increasing in density. At the same time, labor requirements and overall costs must be minimized. RA connectors meet all of these requirements, while providing increased reliability. These connectors, whose materials, shapes, dimensions, and surface treatments have been carefully selected, are based on the latest technological information that has been accumulated and improved over years of experience in crimping connection technology. die. This eliminates unnecessary gold-plating and overall costs are minimized. This innovation is another example of our industry-leading technology. * Selective gold-plated posts Header posts are also selectively gold-plated. While square wire material is used for production of conventional posts in loose pieces, continuous flat strip is used for production of our post in chain form. This allows selective gold-plating and provides cost reduction. * Cost-efficient JST's unique technology allows it to produce connectors that are extremely reliable and cost-efficient. * Interchangeable cables and connectors RA connectors fit commercially available 1.27mm (.050") pitch Short locking lever flat ribbon cables. A variety of ribbon cables are offered according to the purpose. Moreover, the RA series receptacles and header are interchangeable with the similar type of connectors commercially available.
