Micro-D Metal Shell - .050" Contact Spacing MDM
MDM connectors are used in applications
requiring highly reliable, extremely small, light-
weight connectors with higher density contact
configurations than available in traditional rec-
tangular connectors. They are available in 8
shell sizes accommodating from 9 to 100 con-
tacts, and special arrangements of power and
coaxial contacts.
These connectors are designed to meet the rap-
idly increasing demands for an environmental,
high performance, rugged, moisture-sealed
microminiature connector. This connector
employs size 24 MICROPINTM/MICROSOCKETTM
contacts on .050 (1.27) centers in a contact
density identical to the standard MICRO-D con-
nector series, but with these additional features:
•Aluminum shells to provide greater
strength, prevent chipping, cracking or
breaking, offer electromagnetic (EMI) and
RFI shielding.
•Silicone elastomer compression interfacial
seal to provide a moisture and humidity
seal between each contact and between
contacts and shell.

NOTES:
1. Front panel mounting is the preferred mounting
method. Front panel mounting dimensions
(figure1) will accommodate either #2-56 screws
or jackpost hardware.
2. Rear panel mount dimensions (figure 2) will
accommodate #2-56 screw hardwareonly.
When mounting the connector with rear panel
mount jackpost see the panel cut-out
dimensions.
3. Edgeboardmounting bracket (figure 3) uses #2-
56 screws. Dimension .450+/-.002 (11.43+/-
0.05) locates the MDM receptacle flush with the
end of the board.

Save wear and tear on your equipment and
systems connectors by using the "Connector
Saver".
The multi-matings and unmatings experienced
by most connectors during testing and final
check out can be eliminated.
Simply mate the "Connectors Saver" to your
unit and use the opposite side for your testing
interface...less wear, less tear, less chance of
damage. It is available in all eight standard
MDM layouts. Mating hardware is available
and can be ordered either separately or
included with the connector saver.
