Environmental D

D*D

The Cannon D*D Environmental Series is designed

to meet the demand for subminiature rectangular

plugs with superior vibration and moisture resist-

ance characteristics for aircraft, missile, and ground

support equipment applications.

Featuring a rugged aluminum shell and peripheral

seal, the D*D connector meets all applicable re-

quirements of MIL-C-24308. Available in both sol-

der and crimp versions, all assemblies are provided

with nylon potting cups and dust caps.

Solder type contacts are non-removable and are

factory-installed. Crimp type connectors utilize the

field-proven LITTLE CAESAR® rear insertion, rear-re-

lease retention system.

PLEASE NOTE: The D*D Series is not intermate-

able with other D Subminiature connectors.
