• Twin U-slot
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
Short locking lever
RA connectors fit commercially available 1.27mm (.050") pitch
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. Contact JST
before procuring cables and other manufacturer's mating
connectors.
