Backshells and Cable Clamps
Circular connectors are interconnect products characterized by a cross section that is generally circular in shape and have contacts that are typically arranged on a polar coordinate system, rather than on a rectangular grid or coaxially. For products marketed as modular connector systems allowing configuration of a desired connector from a catalog of interoperable components, backshell and cable clamp components are respectively used to cover the non-mating end of the connector and to provide strain relief for attached cabling.
