CA /MS A&B
ITT Cannon is the foremost manufac-
turer of MS and MS type connectors
with the widest range of connector
styles, sizes and variations in the
industry. These connectors utilize the
finest materials, which, along with
precision manufacturing and rigid
quality control, assure ITT Cannon
customers of the finest quality con-
nectors. The MS A & B product line
has environmentally safe green and
black zinc alloy plating. The Black
zinc plating is RoHS complaint. The
plating is a high quality, uniform fin-
ish. The contact, which are preloaded
in the insulator, have been
redesigned such that the solder cups
remain in the proper orientation and
will not rotate during wiring termina-
tion. The contacts are machined for
strength and durability and plated
with silver. The Cannon MS A&B
design meets the performance
requirements of the MIL-C-5015. The

MS A&B
Introduction
CA/MS 3100A wall mounting recepta-
cles are used to carry wires through
walls or bulkheads, or to provide the
means of disconnection at a bulk-
head. CA/MS 3100A receptacles mate
with CA/MS 3106 and 3108 plugs.
A
Circular
CA/MS 3101A cable connecting
receptacles are used for cable
extension
requirements
where
mounting provisions are unnecessary.
CA/MS 3101A plugs mate with
3106A/B and 3108B connectors.
Note:
The D revision of MIL-C-5015
has changed the nomenclature of the
3101 from receptacle to plugs.
CA/MS 3102A box mounted recepta-
cles are used in junction boxes or as
an integral part of equipment. CA/MS
3102A receptacles will mate with
3106 and 3108 plugs.
CA/MS 3106A straight plug utilizes a
solid endbell. The CA/MS 3106A
mates with 3100, 3101, and 3102
connectors
CA/MS 3106B is identical to the
3106A straight plug except it utilizes
a split endbell. CA/MS 3106B mates
with 3100, 3101, and 3102 connec-
tors.
CA/MS 3108B 90° angle plugs are
used where there is limited space ad
where wires must be brought at
abrupt angles. This plug will mate
with 3100, 3101, and 3102 connec-
tors.
