1 j s t j s t j s t jst short locking lever long locking lever 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. features ?conforms to mil standards jst? 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? 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? wealth of mass-production technology allows it to produce connectors that are extremely reliable and cost-efficient. ?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. * rohs compliant products are published. * refer to "general instruction and notice when using terminals and connectors" at the end of this catalog. * contact jst for details. standards 0 recognized e60389 1 certified lr20812 with strain relief without strain relief rx connector disconnectable insulation displacement connectors for 1.27mm pitch ribbon cables 2.54mm pitch
