MULTIPLE CONFIGURATIONS
• Low profile options
• Compatible with many shell sizes
and plating finishes
• Wide variety of modification
options allow customisation of
standard ranges to suit specific
requirements
EASY INSTALLATION
• Tool free ranges available
• Simple and fast termination
solutions
• Two-part components allow
uncoupling for repairs to help
eliminate damage to the boot
HIGH-RELIABILITY
SOLUTIONS
• Backshells can provide strain-
relief and cable support to help
prevent bending or overflexing
• Oer individual or overall 360°
screening against EMI/RFI
interference
• Backshells can oer protection
towards the eectiveness of the
cable, sealing against water and
dirt ingress
For high-performance sealing and strain
relief, the ideal mate for a TE Connectivity
(TE) connector or molded part in a wiring
application, is a TE backshell.
TE supplies a comprehensive range of circular POLAMCO
and Raychem backshells that can assist in providing
effective strain relief, environmental sealing and
electromagnetic interference (EMI)/radio frequency
interference (RFI) shielding, helping you meet today’s
challenges in demanding environments, across many market
sectors.
Spin-Coupling Adapters
Spin-coupling adapters are two-part components that have
a rotatable coupling nut and a grooved body designed to
accommodate lipped-type heat-shrinkable boots.
Spin-couplings with a compatible molded part are used
to optimize environmental protection and strain relief of
unscreened cable terminations. Cable repairs can often be
made without removing the boot.

Rollback Repair Possible With A Backshell
Many cable repairs are made within 75 mm of the
connectors—usually because of a broken pin or wire. By
reheating the heat-shrinkable boot and unscrewing the
backshell coupling nut, the boot can be “rolled back,”
providing access to the rear of the connector for repair. This
technique is applicable to spin-coupling backshells utilizing
a heatshrink boot.

CIRCULAR BACKSHELLS
Selecting A Backshell
TE offers an extensive standard
range of backshell styles to suit a
wide variety of applications and
requirements. These ranges can be
extensively customized using an
array of plating options, materials
and modification codes. Use the
product finder on pages 12-13 to
select the most suitable standard
series for your requirement.
Adapter Code
An alphabetical code is used to identify connectors
with similar adapter interfaces. This code is used to
determine the backshell family and part number. The
table connector interface table on page 9 shows the
appropriate code to match a variety of interfaces.
Backshell Part Number
The part number is the sequence of numbers and
letters that describes the adapter family (or series),
size, angle, material, finish, and modifications. The
part numbering system is explained on page 10 for
POLAMCO series backshells and on the individual
Raychem product pages.
Family/Series
TE offers several families (or series) of backshell
products. Each part number begins with an numerical
or alphanumeric prefix denoting the specific product
family.
Entry Size
Entry size is the diameter of the hole through which
the cable enters into the adapter. If unknown, the
diameter required can be calculated using the formula
shown on page 11.
Shell Size
This is the size of a connector as specified by the
connector manufacturer. It is normally a two-digit
number between 08 and 24, although certain
connectors are obtainable in either larger or
smaller sizes and some use letter codes.
Modifications
Other options (such as extended length, part
marking etc) are available and are defined by
standard modification codes - listed on pages
7-8. Alongside the standard ranges shown in this
brochure, TE also offer custom solutions to fit
more exact requirements. Contact the sales office
to find out more.
Please refer to the fold out interface page (attached to the reverse cover of this brochure)
for interface specific measurements.

Table 1
Calculating Wire Bundle DIameter
Where it is not possible to physically measure the wire bundle diameter it
can be estimated from the individual wire diameters using the following
calculation.
When selecting the backshell cable entry size from provided tables, it is a good idea to err on
the side of too large, as an undersized cable can always be enlarged with tape or a grommet
to fit the cable clamp. When calculating wire bundle diameters, note that the gauge # of the
wire describes only the diameter of the metal conductor, and not the overall diameter including
insulation and/or braids. Refer to the appropriate wire specification for the actual diameter of
the wire for use in the following calculations.
Steps:
1. Determine each type of wire diameter
2. Choose the multiplication factor from table 1 below
3. Calculate the bundle diameter using the following formula:
(Bundle Diameter) = Factor x n1 x d1
2 + n2
2 + d2
2 + n3 x d3
2 + ... + nn x dn
2
Where d1 ... dn are diameters of each type of wire in the bundle (when using wires from dierent diameters)
n1 ... nn the quantity of wires with the same diameter
Factor is chosen in according to the total number of wires in the bundle (TABLE I)
4. Add thickness of any shielding or jacketing to core wire bundle diameter.
(Final OD) = (Bundle Diameter) + 2 x (Shield Thickness) + 2 x (Jacket Thickness)

CIRCULAR BACKSHELLS
Glossary of Terms
Anti-decoupling
Anti-decoupling backshells
incorporate a ratchet in the nut
to help reduce the possibility of
the backshell decoupling from the
connector due to extreme vibration
and shock.
Arctic grip
A deep square-form grip, alternative
to a knurled grip, particularly on
protective covers.
Backshell
Any accessory fitted to the rear
thread of a connector, providing
strain relief, screen termination and/
or cable sealing.
Blanking Cover
Helps to provide environmental
protection and EMC shielding to
circuitry or shorting loops at the rear
of a connector that is to be used as a
stand-alone device.
Cobra Head
Low profile split 90° adaptor.
Conduit
Flexible corrugated tubing that
provides environmental protection for
wiring. Can be used in conjunction
with screenbraid and conduit adaptor
backshells to provide a fully screened
and sealed system.
Connector
Device for electrically connecting
wires to each other or to electrical
equipment.
Direct-coupling
Direct-coupling backshells do not
have a distinct nut, i.e. the entire
backshell rotates when the backshell
is screwed into place.
Dummy Receptacle
Provides stowage, environmental
protection, and EMC shielding for an
unmated plug.
EMC
Electromagnetic Compatibility
assures the avoidance of interference
eects resulting from the
unintentional generation, propagation
and reception of electromagnetic
energy. This can be achieved
by properly grounded shielding
(screening) or by electronically
filtering signals (Filter Connector).
Entry size
Two digits describe the diameter of
the hole through which the cable
enters into the backshell. Check
specific series for details – note that
some series such as boot adaptors
(97 series) and cable clamps (96
series) do not require the entry size
to be stated.
Follower
Refers to the main body of a spin-
coupling backshell.
Heat shrink boot
Molded sleeve that joins the cable
jacket to a suitable backshell,
for purposes of strain-relief and
environmental protection. Heat
shrink boots shrink to fit and are
installed by use of a specialised hot
air gun. Adhesive-lined boots and a
variety of materials are available.
Heat shrink kit
Backshell with pre-installed heat-
shrink boot and optional (internal)
overall screen. Enables easy
installation whereby boot and 360°
screen termination are achieved in
one operation by use of hot air gun.
Individual screen
EMC shield (e.g. screenbraid)
encompassing an individual wire in a
bundle.
Lacing Tape
Lacing cord used as a binding
medium to indicate an EMC
classification of an open wiring
harness.
Overall screen
EMC shield (e.g. screenbraid)
encompassing entire wire bundle.
Protective Cover
Provides environmental protection
and EMC shielding on the front
(mating end) of an unmated
connector.
RoHS
The RoHS Directive bans the placing
on the EU market of new electrical
and electronic equipment containing
more than agreed levels of lead,
cadmium, mercury, hexavalent
chromium, polybrominated biphenyl
(PBB) and polybrominated diphenyl
ether (PBDE) flame retardants.
Screenbraid
Flexible EMC shield in expanding
sleeve form for covering cable.
Shell size
Two numerical digits that state the
size of the connector.
Shield
See EMC
Spin-coupling
Spin-coupling backshells have a
coupling nut that rotates freely on the
backshell body.
Strain relief
Any method of relieving the strain
on the individual wires, should the
cable be put under tension. Common
methods are cable clamps, heatshrink
boots, tie posts.
