Identify
the part number of the cable that
meets the application requirements.
This number is the first segment of
the cable assembly part number. Refer
to cable selection guide in this section
of the catalog.
If
your application demands ruggedization,
the ruggedization code is added at
the end of the cable part number.
|
| Ruggedizations
type P, U or
K offer protection from
humid and/or mildly abrasive environments.
This
type of ruggedization consists of
a protective sleeving over the full
length of the cable assembly. This
sleeving slightly restricts the cable
bend radius.
P
polyolefin sleeving.
(solar and moisture protection)
U
polyurethane sleeving.
(highly abrasion resistant)
K
polyvinylidene sleeving.
(highly flexible, low outgassing)
Type
N ruggedization consists
of a nomex braid generally applied
directly over the FEP outer jacket
of a cable. Nomex provides additional
chaffing and heat resistance in harsh
environments. Ruggedizations type
R, UR or KR
offer very good protection from humid,
abrasive and harsh environments, as
well as crush protection up to 300
lbs per six inches of length. This
type of ruggedization consists of
spiral wound, stainless steel wire,
anchored from connector A to connector
B, covered with a protective sleeving.
|
R
spiral wound, stainless steel wire,
covered with polyolefin sleeving.
UR
same as above with polyurethane sleeving.
KR
same as above with
polyvinylidene sleeving.
Type
A armor ruggedization
is the ultimate protection against
handling. It consists of a helically
wound, flexible type 302 stainless
steel armor that is anchored from
connector A to connector B. The armor
offers exceptionally high crush resistance
and protection from kinking. Cables
measuring less than .240 diameter
have 1,000 lbs/inch crush resistance.
Cables measuring .250 to .360 diameter
have 800 lbs/inch crush resistance.
A stainless steel wire that runs from
connector A to connector B inside
the armor protects the cable assembly
from tension damage. An optional sleeving
applied over the armor offers protection
from humidity and vapors.

2.
Connector A:
Choose
the part number of the connector from the
connector selection guide in this section.
Use the first five digits only.
In
the example, connector 29095-32-22 (SMA
plug, Rt. angle) is selected so 29095
are the only digits used in the cable assembly
part number. The full part number of the
connector is only used when connectors are
purchased individually.
Note:
The termination methods used (the way the
cable is attached to the connector) by Astrolab
depend on the cable dielectric, the outer
conductor and the maximum frequency of the
connector and cable.
As
a general rule all semi-rigid cables are
terminated by soldering the outer conductor
to the connector body.
Listed
below are the most popular Astrolab cables
and the termination method used.

Connector B:
Same
as connector A.
In
the example, the connector selected is part
number 29741-32-22 (N, plug 90° sweep)
so29741 are the only digits
used in the cable assembly part number.
4.
Length:
Cable
assembly length is defined as the distance
between the reference planes or center lines
of connectors A and B. The default unit
of cable assembly length is inches. You
can specify the length of the assembly in
feet (ft), millimeters (mm), centimeters
(cm) or meters (m).
Example:
Assembly 32022-29095-29741-63.5 is identical
to Assembly 32022-29095-29741-1613mm or
32022-29095-29741-1.613m

ORIENTATION
The
letters A through D
are used to define orientation of right
angle and sweep connectors.
Example
32022-29095-29741-63.5A

The
letters E thru H
are used to define orientation of flatsto
flats or flats to 90°
and sweep connectors.

Phase
Matching Option:
Cable assemblies can be phase matched to your specifications. Add PM ±
nnº as an option, where nn is the phase tolerance.
Amplitude
Matching Option:
Cable assemblies can be amplitude matched
to your specifications. Add AM ±
nn as an option, where nn is the amplitude
tolerance.
VP
Option (low outgassing):
The VP option is available for assemblies that will be used in high vacuum or
spacecraft applications. All materials used in assemblies with the VP option meet
or exceed NASA outgassing requirements for TML <1.0% and CVCM <0.10%. The
VP option is placed at the end of the part number, such as '32022-2-29094-12VP'
Attenuators:
If desired, an attenuator can be added to one end of the cable assembly. Refer
to the proper section of this catalog for attenuator availability. Add the attenuator
part number to the cable assembly.
Adaptors:
If desired, one or two adaptors can be used to conform the cable assembly to a
different interface or gender or to protect the primary cable assembly interface
from wear (connector saver). For available adaptors see the adaptor section of
this catalog. Again, add the adaptor part number to the cable assembly.
