Micro-D Metal Shell - .050" Contact Spacing
MDM
MDM connectors are used in applications requiring
highly reliable, extremely small, lightweight connec-
tors with higher density contact configurations than
available in traditional rectangular connectors. They
are available in 8 shell sizes accommodating from 9
to 100 contacts, and special arrangements of power
and coaxial contacts.
PINª/MICROSOCKETª contacts on .050(1.27_
centers in a contact density identical to the stan-
dard MICRO-D connector series, but with these
additional features:
Â¥ Aluminum shells to provide greater strength,
prevent chipping, cracking or breaking, offer
electromagnetic (EMI) and RFI shielding.
These connectors are designed to meet the rapidly
increasing demands for an environmental, high per-
formance, rugged, moisture-sealed microminiature
connector. This connector employs size 24 MICRO-
Â¥ Silicone elastomer compression interfacial seal
to provide a moisture and humidity seal between
each contact and between contacts and shell.
