Radiall MPX EN3682 (MIL-DTL-83527) Connectors
EN3682 (MIL-DTL-8357) Connectors are the More Rugged Version of ARINC 600
Recognized by EN3682 and MIL—DTL—83527, Radiall’s MPX connectors are, most commonly, used in mil/aero applications to connect the equipment rack to the avionics system. This series is known as a more rugged version of the Arinc 600 and delivers high density and robustness to harsh environment type of applications. NSX Series offers numerous contact types for any application—signal, power, coax, twinax, triax, quadrax, and LuxCis Arinc 801).
