Features ––––––––––––––––––––––––
• Conforms to MIL Standards
JST’s RX connectors conform to MIL standards (MIL-C-83503)
and are compatible with its RA connectors.
• Secure locking mechanism
The locking levers are engaged by inserting the receptacle into
the header. This ensures a firm connection that’s highly resistant
to impact and vibration. To save space, JST has also made
available short locking levers which provides a firm connection
even when the receptacle has no strain relief.
• Cost-efficient
To reduce costs, only the mating sections of the receptacle
contacts and header posts are gold-plated. JST’s wealth of
mass-production technology allows it to produce connectors
that are extremely reliable and cost-efficient.
Contemporary needs require that
electronic equipment be high in density,
modular in construction and multi-
functional. In addition, the costs of such
connection systems must be reduced. To
meet these needs, particularly in the video
and audio fields, we offer JST’s highly
reliable and cost-efficient RX connectors.
These connectors reflect displacement
connection technology as well as its
advanced production techniques.
Without strain relief
• Post suited for high-density patterns
The mating section of the header post is 0.64mm square. The
printed circuit board solder section of the post is 0.60mm in
diameter. This small size greatly facilitates high-density design
of printed circuit boards.
