Developed in response to new- ly emerging SCSI applications, it Is also an ideal choice for any applica- tlon requiring a low-cost, right angle PC tail connector. Available in either standard, or reverse polarization, these receptacles are completely intermateable with stand- ard Amphenol micro-ribbon con- nectors. To accommodate PC pane! or chassis thickness, the front shell has been lengthened 0.100. A 0.070 reduction in connector-to-board height, as measured from PCB surface to connector centerline, provides a lower profile to accommodate PC Host Adapter Card/lO Port configurations Beryllium copper contacts feature recessed Closed Front Entry design for improved ESD suppression. The positive mating action of these con- tacts 1s self-wiping and self-cleaning, resulting in highly reliable electrical continuity and low contact resistance. Spring clip or jack screw mounting hardware assures connectors remain tightly engaged.
