Crimp Connectors
DESIGNED TO COMPLY WITH MIL-C-26482
AND BS 9522-N0001, THE SUCCESSOR TO
DEF 5326 Patt. 603
Development and manufacture of 162GB miniature
bayonet lock connectors has been closely
coordinated with the solder version. The entire
programme has been carried out at Amphenol’s
Whitstable Plant. The precision machinery and
measurement control processes used for the
production of 162GB crimp connectors are the same
as those used to produce 62GB solder connectors.
Full intermountability
absolutely guaranteed.
and

are
Audio Applications
Contacts are suitable for tinsel cord applications.
162GB Series crimp connectors share many of the
features of 62GB solder connectors. Coupling is
achieved with a triple-track bayonet locking system
which gives positive alignment on all shell sizes.
When connector halves are fully mated there is a
definite click. Inspection holes in the coupling ring
will then reveal the bayonet pins on the receptacle
which are clearly marked in yellow.
The Amphenol design means simplified removal of
coupling rings for servicing or replacement as they
are
front demountable.
In addition there is a rough
grip heavy duty style for arduous conditions and a
lever coupling ring which allows extremely close
mounting of connectors.
The method of sealing is the same as for 62GB
connectors; using peripheral seals on the rubber
inserts and sealing the mating shells with a square
section gasket. Wire sealing is by multiple risers in
the rear grommet.
Derating
Connectors must be derated under the following operating
temperatures:
1. At elevated temperatures, the current ratings are
reduced as show in the table on page 10.
2. At high altitudes, revised voltage ratings become
effective as shown on page 11.
3. When connectors to different specifications are
intermated (e.g. BS 9522-N001 and MIL-C-26482), the
combination must not be operated under conditions
more severe than the less stringent clause of either
specification.
Amphenol 162GB connectors are designed to meet the
most stringent requirements of both specifications.
Cable Assemblies
Amphenol is fully equipped to undertake the preparation of
all types of cable assemblies complying with the military
vehicles and engineering establishments and fighting
vehicles requirements of the Ministry of Defence – the
Ministry of Environment (Motorways) for motorway control
equipment – the Post Office manufacturing code and to the
British Standards Institute when applicable to Cable
systems. Control procedures carried out in accordance
with MIN DEF 05-21. Approval numbers BS 9000, 1043/M
and CAA AD/1450/58. Moulded terminations form a
specialised service by the company. The process offers
such advantages as a waterproof seal between cable and
connector back-end, mechanical protection, and a
homogeneous joint between moulding and cable.
