this catalog covers the amphenol mil-c-26482, series 2 connectors. these connectors are bayonet coupling type, and they feature crimp contacts that are rear insertable and rear releasable. they can be ordered through amphenol, by military or equivalent proprietary part numbers. the connectors covered in this catalog broaden the miniature cylindrical family of fered by amphenol, so that now users have the broadest range of product available to them. should more information be required concerning the connectors covered in this publication, or if special application needs arise, please contact factory : amphenol 1 page contents introduction 1general description, features & benefits class descriptions, performance specifications insert arrangement chart insert alternate positions insert arrangement patterns shell styles, dimensional data : w all mounting receptacle, narrow flange 8 w all mounting receptacle wide flange 9 cable connecting receptacle 10jam nut receptacle 1 1 straight plug, straight plug with rfi grounding fingers 12 contact information, sealing plugs, crimping & insertion/removal t ools 13 ordering information 14 5-7 4 3 2 series ii introduction
amphenol miniature cylindrical mil-c-26482, series 2 connectors amphenol 2 amphenol broadens their miniature cylindrical family of connectors with the addition of the product line of mil-c-26482, series 2 connectors. this series provides a bayonet coupling connector with crimp rear insertable, rear releasable contacts. design characteristicsmedium size, environmentally resistant connector recommended operating voltage to 1000 v ac (rms) at sea level quick positive coupling assured by 3 point bayonet coupling system v isual confirmation of complete coupling eliminates mismating by the use of five key/keyway designinsertion and removal of contacts from the rear of the connectors assures no damage to the front that might af fect the sealing characteristics utilizes same standard qualified rear release type plastic tool for contact insertion and removal contacts are qualified to mil-c-39029 requirements - bin coded (three colour bands), and are crimped with standard crimp tools per mil-c-22520 grommets are constructed of tear-resistant elastomer and experience no degradation when exposed to a broad range of fluids sealing over a range of wire diameters is assured by a triple webbed grommet at the rear of the connector closed entry socket side of the insert is designed with a lead-in chamfer and a hard face that will accept a pin contact bent within pre-established limits elastomer interfacial seal on the pin side has raised barriers around each pin which displace into the socket chamfer when mated, providing a positive moisture seal cust omer options shell styles within this family include: w all mount with either a narrow or a wide flange, jam nut single hole mount, and cable connecting receptacles, along with standard plugs or plugs with rfi grounding fingers, in shell sizes 8 to 24 ms and proprietary versions availableaccommodation of contact sizes 20, 16 and 12 34 insert arrangement patterns available, accommodating from a minimum of 3 to a maximum of 55 circuits alternate positioning availablev arious finishes are available (for information on non-cadmium zinc cobalt plating, consult factory) ms 3 4 7 0 wa ll mo un tin g r e ce pta c l e wit h n ar r o w f l a n g e ms 3 4 7 2 wa ll mo un tin g r e ce pta c l e wit h wi de fl a ng e ms 3 4 7 1 c a b le con n e c ti n g re c e p tac le ms 3 4 7 4 jam n ut r e c e p t a c l e ms 3 4 7 6 str a i g h t p l u g ms 3 4 7 5 plug wi th rfi grou nd ing fi n g e rs series ii
