BACC (Boeing) Connectors

Part Number Prefix: BACC63

aero-electric-26482

BACC63 is a Boeing-developed specification for high-reliability circular connectors widely utilized across commercial and military aerospace applications. These connectors are engineered to survive harsh operating environments, featuring robust construction that provides essential EMI shielding, environmental sealing, and resistance to extreme shock and vibration. They are frequently deployed in mission-critical systems, such as engine bays, landing gear, and avionics control instrumentation.

Design Characteristics

  • - Coupling Mechanisms: These connectors are available with threaded (often tri-start) or bayonet coupling styles.
  • - Material and Construction: Shells are manufactured from passivated stainless steel, aluminum, and lightweight composite materials.
  • - Designed to withstand harsh conditions, BACC63 connectors provide effective environmental sealing against moisture, dust, and fluids.
  • - This series offers EMI/RFI shielding, often utilizing conductive shells and metal-to-metal coupling to maintain signal integrity.
  • - BACC63 is built upon established military specifications, such as MIL-DTL-83723 Series III or MIL-DTL-26500.
