ELECTRICAL DATA - page 231
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.
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-
