range ms series-750 ms circular coupling connectors these are circular threaded coupling connectors designed to jss 50812 (equivalent to mil c 5015). the housing is aluminium alloy having olive green, corrosion resistant, cadmium plating for extreme operating conditions. the insulator is made of a specially developed polychloroprene (neoprene). this gives a high degree of insulation resistance and dielectric strength, along with resilience to withstand shock, impact, and vibration. pins are copper base alloy - silver plated, available in a range of current ratings from 10 amps to 150 amps. these offer excellent conductivity under severe service conditions with minimum loss or discontinuity of current even in dynamic applications. a large array of over 100 insert arrangements in 13 shell sizes for power, signal, and combinations of power and signal pin configurations are available for a variety of applications. these connectors are qualification approved by lcso (electronic components standardisation organisation, ministry of defence, govt. of india) new features include provision of grounding pins, emi - rfi shielding, adapters that can accept international pg cable glands (pg and metric), electroless nickel finish, eco-friendly zinc finish special backend fittings for heat shrink termination, crimp contacts and termination (in select sizes). special variants to ms connectors are available or can be developed to suit specific requirements. http://www.alliedconnectors.net/rangems.html [03-01-07 11:04:30]
