• Twin U-slot ID section
The twin U-slot is the most
important IDC element in
JST’s RA connectors. As
shown in the figure, wire
conductors are connected
between the slots of U-shaped
parallel beams, and the
distance between each adjacent
pair of beams is 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 pitch flat
ribbon cables. A variety of ribbon cables are offered according to

are interchangeable with the similar type of connectors
commercially available. Contact JST before procuring cables
and other manufacturer’s mating connectors.
