Connectors and contacts
Bus 1553 B connectors
The increase of on-board equipment and the implantation of local net-
works (Bus networks) have produce major space and weights
savings.
The most common standard is the Bus, MIL-STD 1553 B.
It has various applications : • Missiles,
• Launchers,
• Tanks,
• Helicopters...
• Single-way connectors with triaxial interface
