high density dual port series connectors utilize two high density connectors vertically stacked and assembled into a single connector unit, which permits saving of panel and printed board space, and decreases final assembly costs. high density dual port series connectors are professional quality connectors recommended for use in sheltered, non- corrosive indoor and outdoor environments having normal ventilation. connector contact variants are 15, 26, 44 and 62. connector gen- ders can be mixed, i.e., one male and one female connector within one high density dual port assembly. the two connectors may be spaced apart to three standard dimensional spacings. the connector may also be partially populated with contacts which are installed in the connec- tor body to customer selected contact positions. mounting angle brackets can be ordered riveted to the connector by specifying r2, r6, r7 or r8 options. locking systems are available uti- lizing 4-40 threaded jackscrew systems, polarized or non-polarized, or with a quick release vibration lock system for either front or rear panel mounted connectors. high density dual port series connectors comply with the dimen- sional requirements of mil-dtl-24308. materials and finishes: insulator: glass-filled polyester per mil-m-24519, ul 94v-0. black color. contacts: male and female contacts precision machined high tensile phosphor bronze. contact plating: gold flash over nickel plate. other finishes available upon request. shells: steel with tin plate, or zinc plate with dichromate seal. other materials and finishes available upon request. mounting spacers and brackets: steel or brass with tin plate, or zinc with dichromate seal. cross bar: nylon resin, ul 94v-0, black color. push-on fasteners: beryllium copper with tin plate. jackscrew systems: steel with zinc plate and dichromate seal, or clear zinc plate. vibration lock systems: lock tabs, steel with nickel plate. electrical characteristics: contact current rating: 3 amperes. initial contact resistance: 0.010 ohms maximum. proof voltage: 1,000 v r.m.s. insulator resistance: 5 g ohms. clearance and creepage distance [minimum]: 0.039 inch [1.0 mm]. working voltage: 300 v r.m.s. mechanical characteristics: fixed contacts: size 22 contact, male contact 0.030 inch [0.76 mm] diameter. female contact rugged open entry design. contact retention in insulator: 7 lbs.
