Commercial Aerospace

Commercial aerospace circular connectors qualified to ARINC and EN standards are specified for avionics bays, airframe wiring, cockpit controls, and cabin distribution on commercial transport and business aircraft. ARINC-format circulars must meet strict dimensional interchangeability requirements while providing sealing and vibration performance demanded by aircraft OEMs and MRO programs. EN2997, EN3155, and related European aerospace connector standards govern insert arrangements, plating systems, and qualification testing for in-service platforms. Amphenol Commercial Air Division designs and manufactures ARINC-compliant circular connectors optimized for avionics bay installations, with traceability and lot documentation aligned to AS9100 requirements. Amphenol PCD offers complementary EN-series circular solutions with broad insert arrangement coverage for European and North American aircraft programs. Together, these two business units address the full range of commercial aircraft circular connector requirements from design-in through long-term production support.
