Amphenol Micro-Ribbon connectors 57 series general configuration 57 series solder termination description Micro-Ribbon connectors offer a fast, economical and distinctively different method of achieving electrical interconnection. The heart of the connector is the ribbon contact, selectively plated gold over nickel on a copper alloy base. With contacts designed to mate easily and positively, the 57 series Micro-Rib- bon connector delivers electrically and mechanically sound interconnections time after time. Exceptionally versatile, 57 series Micro- Ribbon connectors are available in rack and panel, cable to panel, cable to cable and printed circuit types. features @ Copper alloy contacts, selectively plated gold-over-nickel for excellent current-carrying characteristics. @ UL 94 VO rated diallyi phthalate di- electric per MIL-M-14G Type MDG, for operation at up to 700 volts D.C. (sea level) without shorting or flashover. Resists cracking or chip- ping and has low moisture absorp- tion. @ Float bushings on receptacles allow .020 radial float, for easy mating. e Zinc-plated steel outer shell, with clear chromate finish, for corrosion resistance. e@ Wide, flat mating surfaces, pressed tightly together by flexing action of both contacts, for electrical continu- ity. @ Positive mating action that wipes contacts clean, removing film or for- eign matter, for low contact resis- tance. @ Soider cup type contact tails (for easy wire attachment) and pin style tails (for printed circuit board attach- ment) both are available. A high bar- rier between contact rows also is available. e A trapezoidai-shape shell that assures correct polarity.
