• 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.
