If you need to identify a code not listed, please call your RS Techno-Geek!A Guide to 62GB Connectors862GB - SPECIFICATIONSB asic ConstructionThe normal shell finish used, which has a high resistance to corrosion, is zinc cobalt olive drab.

6 Other finishes may be supplied to special order, such as cadmium plate which is available by adding deviation (714) to the end of partnumber. Inserts are of polychloroprene rubber compounded to an Amphenol specification. Operating temperature range is -55 C to 125 C, and the connectors have gold-plated contacts designed for soldered connections. Configurations for size 20 contacts range between 2 contacts in the size 8 ( diameter) shell up to a maximum of 61 contacts in the size 24 mm ( diameter) shell. Hermetic connectors with glass sealed dialectric are manufactured with mild steel shells and nickel ironcontacts plated tin over SpecificationsBritish Standards Specification BS 9522 FOO 17 closely corresponds to the United States Military Specification MIL-C- 26482 solder terminations.

7 Approved gauges are used to check interchangeability of 62GB series with other connectors manufactured to BS 9522 FOO 17 or must be derated under the followingoperating conditions:1. At elevated ambient temperatures, the current ratingsare reduced so that total maximum hot spot temperature of 125 C is not At high altitudes, revised voltage ratings become When connectors to different specifications are intermated ( BS 9522 FOO 17 and MIL-C26482), the combination must not be operated under conditions more severe than the less stringent clause of either specification. Amphenol 62GB connectors are designed to meet the most stringent requirements of both bayonet lock connector series, developed and manufactured in the by AMPHENOL Ltd, having full qualification approval to British Standards Specification BS 9522 F0017 and British Defence Specification DEF STAN 59-35 (Part 3) Sec.
