D Subminiature Military/High Reliability
TT Cannon Military/High Reliability D
Subminiature connectors are used in many
Iapplications, 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 fixed
contacts in solder cup, straight and 90 PC contact
terminations are qualified to MIL-C-24308 (see
cross reference, pages 142-143). These high-
reliability D Subminiature connectors are the finest
quality connectors available at the most
competitive prices in the market.
Applications:
Aerospace
Transportation
Communication Systems
Information Systems
Test Equipment
