Reliability and Versatility
GD* connectors are ideal for aerospace, military,
telecommunications and other applications requir-
ing environmental 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.
Environemental protection is accomplished by the
resilient grommet, interfacial seal, and bonded
connector components.
