Custom Back Shell Systems
ITT has designed numerous back shell solutions for
micro miniature interconnects for many harsh envi-
ronment applications. Although ITT does not offer a
standard back shell portfolio today, we can design
and manufacture a range of back fittings for our
MDM connector products depending on the cus-
tomer requirements. Utilizing one of our partnership
relationships, one of our UK based micro product
groups of ITT can provide can provide custom
designs utilizing proven banded systems in which
the braid is captivated over a chimney style outlet.
These types of back shell systems are available in
Sealing Gaskets
We have received requests for gasket materials to seal the MDM connectors into various enclosures. We recommend that you consider wider flanged connectors
together with a low cost conductive gasket to provide an adequate surface area. This combination will give you IP-66 sealing with good EMC compliance. The follow-
ing dimensions for gaskets and flange dimensions are regarded as the minimum that you should consider.
Conductive elastomers generally offer a superior shielding performance when compared with alternatives as in table below.
* Neoprene is a trademark of Dupont
Conductive rubber gaskets can be loaded with many different metallic fillers but the choice of material is dependent upon a number of factors such as level of con-
ductivity, shielding effectiveness, galvanic compatibility and cost.
Galvanic Corrosion can occur when two dissimilar metals are in contact with one another in the presence of an electrolyte. The type of gasket material has to be
assessed because of the use of metallic fillers. Many applications are dry indoor environments where corrosion is not a major concern. However, for external use,
particularly marine, it is recommended that consideration be given to compatibility. The table on the next page is a summary.

different material finishes and sizes and can be pro-
vided with special process termination methods. In
addition, ITT has developed a method of riveting the
back fitting to the shell within the jacking area. This
option guarantees 360 degree shielding effective-
ness even when jackscrews or jacking posts are not
being used.
Where a conduit system is preferred such as for test
box environments in field locations, back fittings and
a fully screened weatherproof convoluted trunking

Custom Back Shells
In addition to the above ITT can provide special
back potting style termination systems for environ-
mental protection and strain relief. These types of a
back shell style system are typically filled with epoxy
or other encapsulating materials to provide a robust
and effective back shell system.
