See page for dimension table. RoHS Non-Compliant standard finish (no deviation code) of olive drab chromate over cadmium plating. The inserts are also RoHS Non-Compliant as the solder cups contain tin/lead solder. Non-Compliant assemblies are also offered with finishes of clear chromate over cadmium plating (639), black zinc (621), and electroless nickel (689). RoHS Compliant connector assemblies are on pages 1231 and 1232 for solder type, and on page 1233 for crimp type. See pages 179 and 180 for cable clamps and other accessories.
MIL-C-5015 style, provides the interconnection solution for low cost. Shell components are fabricated from high grade aluminum alloy to provide strength and environmental protection. Connector components are fabricated from high grade aluminum alloy, with a conductive cadmium plate finish and an olive drab chromate after-treatment. Some cable clamps are a zinc alloy with an olive drab⁄green chromate finish. Contacts are silver plated with pre-tinned solder cups
