The Amphenol R27 Series is a robust rectangular connector designed to
meet or surpass all the requirements of the MIL-DTL-83527 specification and
EN 3682 European Standard. This series is particularly well suited for military and
commercial aircraft applications where harsh environmental issues are a concern.
Connectors, shells, inserts, termination modules and contacts are sold separately or
fully assembled.
