Amphenol ® 62GB
solder connectors
This miniature bayonet lock connector series offers
designers important features not found in any other range
of connectors.
62GB Series connectors – compliant to the United States
Military Specification MIL-C-26482E on certificate No.
1713. 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.
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.
At high altitudes, revised voltage ratings become
effective as shown on page 7.
When connectors to different specifications are
intermated, the combination must not be operated
under conditions more severe than the less
stringent clause of either specification.
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. For other finishes available, please see part
number breakdown
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 dielectric are
manufactured with mild steel shells and nickel iron
contacts plated tin over copper.

Other finishes are available on request.

Protection Against Mis-Mating or Cross-Plugging
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 available in positions w, x, y and z.
These are to be requested via the part number
configuration. See part number breakdown.
