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.
