The HEX40-KC-45-21-A9-1 is a circular MIL spec backshell manufactured by TE Connectivity Aerospace, Defense and Marine. It belongs to the HEX40 series and is designed for use with specific circular connector assemblies. The component features a 45-degree angled exit configuration, providing strain relief and cable management in constrained environments. It is constructed to meet rigorous military specifications for durability and environmental resistance.
Verify exact part number alignment with engineering drawings before procurement. Confirm that the 45-degree orientation matches system requirements. Check for any recent obsolescence notices or lifecycle changes from the manufacturer. Ensure compatibility with the specific connector shell size designated in the model suffix.
Select this component when a 45-degree cable exit is required for MIL spec circular connectors. Compare against straight backshells if space constraints differ. Verify that the housing material and finish are suitable for the intended operational environment. Ensure the connector series compatibility matches the application design.
This part is part of the HEX40 series of circular connector accessories. It serves as a critical interface between the connector body and the cable assembly. The series is known for robust construction suitable for demanding applications. It complements other components in the MIL spec connector ecosystem.
Consult official substitution lists for direct equivalents. Generic alternatives may not meet MIL spec requirements. Verify dimensional and electrical continuity if cross-referencing with similar angled backshells.
