Advantages
AFD
Representing the most advanced design in use which both reflects and sets the pace for future developments, Compagnie
DEUTSCH presents its AFD series connectors meet requirements of MIL-C 26482 G series 2 bayonet coupling connectors.
The Compagnie DEUTSCH AFD series connectors offer several advantages over previous devices such as :
•
Higher performance characteristics.
•
Completely sealed against rigorous environments.
•
Reduced assembly and rework costs.
•
Simplified assembly procedures.
•
Hard plastic socket interface prevents penetration of bent pins.
•
Rear release system from the rear of the connector.
•
RFI fingers available for AFD 57 only.
•
Intermateability and interchangeability with Compagnie DEUTSCH series connectors :
- 951 meet requirements of NFL 54125 B and UTE 93422 model HE 301 B.
- FDBA meet requirements of MIL-C 26482 and UTE 93422 model HE 302 and 303.
•
Available in 9 shell sizes and 27 various insert arrangements.
•
Hermetically sealed electrical connectors in DBC version.
