1 IDC.54mm R CONNECTOR IDC Disconnectable Insulation displacement connectors for.7mm pitch ribbon cables pitch Features Twin U-slot ID section The twin U-slot is the most important IDC element in eam JST s R connectors. s shown in the figure, wire conductors are connected Slot eam eam supporter between the slots of U-shaped parallel beams, and the Conductor distance between each adjacent pair of beams is designed to be one third of the pitch of wire Double-leaf contact strands. Two-die processing and selective gold plating Two precision dies are used to blank and form the contacts. fter 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. t the same time, labor requirements and overall costs must be minimized. R 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 R connectors fit commercially available.7mm pitch flat ribbon cables. variety of ribbon cables are offered according to Short locking lever the purpose. Moreover, the R series receptacles and header are interchangeable with the similar type of connectors commercially available.
