general description
Amphenol
MIL-DTL-5015 Type Cylindrical Connectors and Heavy Duty MIL-DTL-22992
Connec tors. They offer the same durability advantages and design benefits for
reliable interconnection as the Amphenol coax contacts used in high performance
D38999 connectors. A variety of military and commercial shielded cables are
accommodated within these cylindrical series.
Other features of the coax contacts available for MS/Standard and Heavy Duty
cylindricals include:
•
•
•
•
•
Several insert arrangements that can incorporate:
• Size 4, 8 and 12 coax contacts
Advanced shielding wire technology in a rugged military connector
Single connector with multiple coaxial connection eliminates cross-mating
Positive contact captivation - especially important in these series with its much
higher coupling/uncoupling force
Older shielded cable type availability
