Subminiature connectors are used in many
applications, including aerospace,
transportation, communication systems,
information systems and test equipment. Being the
inventor of the D Subminiature connector,
ITT Cannon is able to use its extensive design
expertise and high quality manufacturing
processes to insure the optimum performance and
reliability.
The D Subminiature connectors with xed
contacts in solder cup, straight and 90° PC contact
terminations are quali ed to MIL-C-24308 (see
cross reference, pages 142-143). These high-
reliability D Subminiature connectors are the nest
quality connectors available at the most
competitive prices in the market.
Applications:
Aerospace
Transportation
Communication Systems
Information Systems
Test Equipment
