ITT Cannon Space Connectors
As a world leader in connector technology, ITT Interconnect Solutions
occupies the enviable position as the primary supplier and innovator in
mission critical space applications. Cannon's products have served on
every free world space mission since the inception of space exploration,
over 50 years ago. Reflecting this achievement, the United Space
Alliance recognized ICS in 2007 with a certificate of appreciation for
our efforts in supporting the shuttle and space station programs.
Today, ITT ICS supports global space initiatives with one of the indus-
try's broadest portfolios of high reliability,
space grade products. Coupled with our
extensive custom Engineering capability,
Cannon provides unrivaled support and
design expertise to the pioneering space com-
munity.
Connector Types
There are three major categories of High
reliability connectors used in space flight
application: D-Subminiature, Micro-miniature,
and Circular, including Filters and Specials for
all categories. The selection process depends
on the type of application and size require-
ments; D-subminiature and Micro-D connec-
tors are widely used on PCB and panel mount
applications, as well as light duty cables. Circulars
are typically used more for heavy duty cable and
panel mount applications. Consequently, D-Sub type

connectors typically favor Satellite applications whereas circular connectors favor launch and
crew manned vehicles.
Design and Materials
All space grade connector products meet the design and materials requirement of both
NASA/GSFC and the European Space Agency. The key considerations for design conformance
includes the adherence to Mil-Spec design standards that ensure the capability for interconnect.
For D-Subminiature connectors, this standard is M24308, for Micro-D’s it is M83513, and for
Circular connectors it is M38999. NASA and ESA requirements deviate from these standards by
recommending materials that ensure low levels of residual magnetism (or magnetic permeabili-
ty) and materials outgassing. Many manufacturers of connectors use elastomers and plastics
which contain compounds that may outgas over time. It is essential that these compounds be
removed prior to final assembly and launch, usually by means of a bake-out process. It should
be noted that ITT Cannon is one of the only space connector manufacturers that has developed
specialized polymers that meet NASA and ESA outgassing requirements, even prior to bake out.
Quality Testing
NASA and ESA requirements specify that both screening and qualification testing be performed
on all connectors used in space flight applications. NASA and ESA follow similar requirements
as they jointly participate in programs that require intermateability and similar quality standards
on mission critical applications. In some cases, qualification requirements may vary depending
on the critical nature of the mission. Consequently, qualification may be periodic for a specific
connector type or lot specific for a particular mission..
