R27 Series MIL-DTL-83527

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.

These connectors are intermateable and interchangeable with filtered and nonfiltered MIL-DTL-83527 connectors. A wide range of contact arrangements is available using contact types from Fibre Optic, Quadrax, Differential Twinax, Triax, Twinax and Coax to the standard size 12, 16, 20 and 22 contacts, in crimp and PCB. These connectors are offered in both filtered and non-filtered designs. Filtered designs incorporate Amphenol’s solderless construction which reduces stress on the ceramic elements resulting in superior thermal and physical shock performance and unparalleled long-term reliability. Custom designs and features such as termination modules, backshells, unique insert patterns and integral shells are also available.


  • Enhanced environmental sealing

  • More robust and durable shells

  • EMI Shielding springs

  • Interchangeable insert patterns with ARINC 600 models

  • Available in both filtered and non-filtered
