rf interconnect products
Introduction
Established in 1960, Trompeter is a manufacturer of high value wireline coax, triax, and twinax transmission line
connectors, cable, and the tools required for assembly. In addition, the company has a broad line of patch panel insertion-
controlled interconnect modules and a rapid response cable assembly business. The firm is ISO-9001 registered and
enjoys an international presence in the Telecommunications, Broadcast, and Military/Aerospace markets.
MIL-STD-1553B Digital Data Bus Applications
Twinax /Triax connectors are used in military applications to protect data signals from extraneous noise through non-
signal-carrying shielding. Interfacing connectors must provide contact surfaces isolated from each other and from their
outer shields. MIL-STD-1553B addresses twinax applications for computerized/multiplexed digital data distribution
systems servicing the many functions of
Command, Control, Communications, Computers
and
Intelligence
(C
4
I)
which
was originally designed for military aircraft. MIL-STD-1553B applications are found in military surface ships, battle
tanks, helicopters, missiles, space vehicles, combat aircraft and in many ground applications such as data networks and
perimeter security for airports, armories, and other government installations.
The great advantages of additional information, automation and weight savings, which are necessary for the complex
demands of aircraft operations are realized by using a single transmission cable instead of the complicated, heavy,
dedicated multiple cable used in the past. A 78Ω twinax cable was selected to provide the transmitted digital information
with the needed protection from magnetic, electrostatic and electromagnetic pulse (EMP) interference. Complete
shielding of the twisted pair along the transmission path and all electrical contacts within multi-pin connectors must be
maintained.
Trompeter
provides matching components of Twinax/Triax connectors and cable for improving the transmission
capabilities and interference rejection of data transmission systems. Trompeter components will meet or exceed MIL-
STD-1553B requirements (for airborne and ground checkout) and MIL-STD-1760 "External Stores".

Trompeter quality
Quality Standard and Custom Components
For over thirty years, Trompeter's product offering have grown as a result of new and modified designs for unusual
applications. With Trompeter's tradition of custom components comes our reputation for providing rugged products that
have been designed to perform to your expectations and to meet your specific mechanical requirements. The growth of
our product line, from 78 components in 1964 to more than 7,000 end items (over 20,000 configurations), is proof of our
engineering and manufacturing capabilities.
Why compromise your design?
A minor modification might be an affordable solution to your design needs.
Why settle for less than Trompeter?
Superior quality is paramount.
Trompeter components meet your most demanding requirements...
When performance is critical.
When compromise is not an acceptable solution.
When cost savings detract from the integrity of your design.
ISO 9001 Registration
The main value of being an ISO 9001 Registered company is in the assurance to our customers that we have a solid quality
system in place, and that it is well documented. DET Norske Veritas (DNV) has certified that Trompeter is in compliance
with established systems and policies. ISO 9001 Quality System Standard is a document outlining twenty elements of
quality that Trompeter has addressed in order to meet registration requirements. An accredited ISO 9001 auditor must
verify, through on-site audits, that a company has a well documented quality system in place that meets the requirements
of ISO 9001, and that the company is working in accordance with the documented system. Trompeter's quality system
is also certified by numerous other accredited agencies. ISO 9001 registration makes Trompeter an edge in the global
market by giving customers the assurance that they are dealing with a company dedicated to meeting their quality
expectations.
3-Year Warranty
All Trompeter products carry a
"Three Year Warranty"
(except
the battery powered cable stripper)
and meet or exceed
the highest industrial and government standards, such as MIL-C-39012 and MIL-C-49142. More importantly, Trompeter
connectors are designed to meet your design specifications which are often more demanding and less forgiving. We have
built our business on responding to your special needs for uncompromising performance in a world of increasing pressure
from global competition. If, within three (3) years of shipment, any of our products fail to meet your expectations due
to defects in material or workmanship, we will gladly repair or replace it free of charge.
Custom Product Requests
The products in this catalog are your first resource for solving your special interconnect problems. If you cannot find
an adequate solution, then we invite you to consult with us for your special requirements. If you have an application which
requires a new product, or a modification to one of our existing products, please fill out a copy of the Custom Products
Request Form on page 137 and fax it to us. Please submit one complete form for each product requested. Requests for
new/modified products are evaluated weekly, and you will receive a response within 3-5 working days.

Space-qualified connectors
Outgassing Requirements
for Space Rated Connectors
Trompeter has a long and proud history of servicing space applications.
NASA
uses the specification
(SP-R-0022),
Vacuum Stability Requirements of Polymeric Material for Space Application, to qualify materials for use in spacecraft.
This has also become the standard in the commercial space industry. This specification governs the "outgassing" of non-
metallic materials. Outgassing occurs when a non-metallic material is placed into a vacuum, subjected to heat, and some
of its constituents are volatilized.
One of the bi-products of outgassing is that the material loses a portion of its mass. This is referred to as Total Mass Loss,
or TML. Under the NASA specification, the material's TML should not exceed 1.0% of the total specimen mass. This
issue is very important because shrinkage may contribute to the failure of a connector as the connector components will
no longer fit properly.
Another bi-product of outgassing is Collectable Volatile Condensable Material (CVCM). This represents the quantity
of outgassed matter that condenses and collects on a surface. Under the NASA specification, the maximum condensable
material allowed is 0.1% of the total specimen mass. This is very critical in a thermal/vacuum environment because it
is the condensed material that will contaminate optical and sensory surfaces causing them to possibly fail.
Some polymeric materials meet the requirements of a TML less than 1.0% and CVCM of less than 0.1% through the
normal manufacturing process. Other polymeric materials, while not within limits after their manufacture, can be
brought within vacuum stability limits by vacuum baking for a specific period of time (usually 48 hours at maximum
use temperature at a pressure less than 10
-5
torr). If a material cannot be vacuum baked, its exposure area is 13cm
2
or less,
and is out of sight of a payload or other critical surfaces, then a TML not greater than 3.0% and a CVCM not greater than
1.0% is acceptable.
Test conditions are ASTM E-595 or ASTM F-1227. The test consists of heating a sample to 125°C for 24 hours under
a 10
-5
torr vacuum and measuring the weight loss and any material that condenses on an adjacent cold surface area (25°C).
The most common candidates for outgassing in Trompeter product lines include:
1. Silicon rubber per ZZ-R-765E/GEN (Federal Spec), Class 2B, Grade 40, 50, 60, and 70. Almost all of
Trompeter's gaskets are manufactured from this material. These materials require a post process
(by Trompeter) at 200°centigrade for 6 hours minimum.
2. Ink. Trompeter uses Markem
TM
series 7224 inks (in a variety of colors) for part marking. Only blue 7224
Markem ink has acceptable TML (0.43%) and CVCM (0.07%) readings after a post cure process. While this
is acceptable, Trompeter recommends impression stamping the connector rather than ink marking.
3. Shrinkable strain relief/sealing sleeve. Sleeves made from Kynar
TM
material meets the requirement for
outgassing at 0.14% TML and 0.02% CVCM.
4. Insulators. At Trompeter, the majority of dielectric insulators are made from PTFE. (Teflon
TM
is Dupont's
trademark for PTFE, FEP, and PFA fluoropolymer resins). PTFE has excellent TML (0.07%) and CVCM
(0.01%) readings. The loss rate is about one-tenth of the acceptable maximum rates for spacecraft uses.
