Amphenol ® 62GB
solder connectors
T
his miniature bayonet lock connector series offers
designers important features not found in any other range
of connectors. The range has full qualification approval to
British Standards Specification BS 9522 FOO 17 and British
Defence Specification DEF STAN 59-35 (Part 3) Sec. 7.
62GB Series connectors - developed and manufactured
entirely in the United Kingdom by Amphenol Limited. They
are the first and only British connectors to have achieved
this. A doubly strong position which Amphenol are well
geared to handle. The manufacturing facilities of the
Whitstable plant have been cited as exemplary in Europe.
Certainly the layout is extensive and extremely efficient;
safety awards have been attained every time returns have
been submitted to the British Safety Council.
62GB Series connectors have been well established with
Government authorities on an international scale and users
can be found in Sweden, Denmark, Norway, Finland,
Germany, Spain, Holland, India, Canada and Italy.
Derating
Connectors must be derated under the following
operating conditions:
1. At elevated ambient temperatures, the current ratings
are reduced so that total maximum hot spot
temperature of 125°C is not exceeded.
2. At high altitudes, revised voltage ratings become
effective as shown on page 7.
3. When connectors to different specifications are
intermated (e.g. 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
specifications.
Military Specifications
British Standards Specification BS 9522 FOO 17
closely corresponds to the United States Military
Specification MIL-C-26482 solder terminations.
Certain differences exist between the schedules which
can be seen on pages 2 and 3.
Approved gauges are used to check interchangeability
of 62GB series with other connectors manufactured to
BS 9522 FOO 17 or MIL-C-26482.
Basic Construction
62GB Series can be supplied in brass or stainless steel.
The normal shell finish used, which has a high resistance to
corrosion, is zinc cobalt olive drab. Other finishes may be
supplied to special order, such as cadmium plate which is
available by adding deviation (714) to the end of part
number.
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
12.7mm (0.5in diameter) shell up to a maximum of 61
contacts in the size 2436.1 mm (1.5in diameter) shell.
Intermediate sizes, and contact data for heavier current
ratings are shown in the insert availability chart on page 6
and 7.
Hermetic connectors with glass sealed dialectric are
manufactured with mild steel shells and nickel iron
contacts plated tin over copper.
* Other finishes ar e available on request.
Protection Agai nst Mis-Mating or Cross-Plugging
In BS 9522 FOO 17 positive shell-to-shell keying is
provided with keys and keyways in a choice of either the
normal (N) or any of the four preferred alternate
positions: B, C, E and F. This prevents mismating between
shells of different orientations and overcomes the
difficulties associated with rotated inserts and a standard
key-keyway orientation. In the latter system, damage to
the inserts or contacts can result if excessive force is used
to engage non-mating pairs.
Rotated inserts are, however, permissible in BS 9522 FOO
17 connectors if required to mate with or replace units to
MIL-C-26482 mounted in existing equipment. Connectors
have normal orientations manufactured to BS 9522 FOO 17
or MIL-C-26482 are fully intermateable as also are
connectors with inserts in positions W, X, Y or Z.

NOTES
* This insert arrangeme nt is not incl uded in B.S.
spec., but is available and. listed in MIL-C-26482.
g Due to the arrangement of contacts in the
14-12 insert arrangement it is classified, for
current derat i ng , in the shel l size ra ng e 18-24.
Lettering of inserts shown above corresponds to view of fron t
(mating surface of pi n inserts or rear face (cable accessory
end) of socket inserts.

CURRENT RATING
Maximum current per individual contact (in isolation) at a
maximum ambient temperature o f 85°C: Size 20 contact 7.5A
Size 16 contact 13-OA The performance of 62GB Series
connectors at all times exceeds the maximum c ontinuous
bunched rating of the app ropriate size wire, or cable of
equiva lent temperature rating. This bunched rating i s therefore
the determining factor. In the case of mixed loadings, the
greatest individual load shall be the bunched loading. In any
combination of ambient temperature plus temperature rise due
to current flow through the contacts, the maximum connector
internal hot spot temperature of 125°C must not be exceeded.
That is, when only one contact per connector is load ed.
