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.

Product Features
  • Enhanced environmental sealing
  • More robust and durable shells
  • EMI shielding spring
  • Interchangeable insert patterns with ARINC 600 models
  • Available in both filtered and non-filtered
