• Environmental Protection
• MIL-C-4308 Compatibility
• Reliability and Versatility
GD* connectors are ideal for aerospace, mili-
tary, telecommunications and other
applications requiring protection and high
reliability.
ITT Cannon developed GD* connectors to
meet the needs of the avionics industry.
These connectors provide high-density and
moisture protection.
Environmental protection is accomplished by
the resilient grommet, interfacial seal, and
bonded connector components.
