The strong and lightweight machined aluminum backshells provide additional strain relief. They are designed to accommodate flexible, abrasion-resistant metal braiding and are supplied with tie-bands to attach the braiding to the shell. The backshells, together with the braiding, provide shielding for enhanced electrical continuity and effective EMI/RFI protection. Mating backshells for use with vertical PCB-mounted connectors or panel-mounted cable connectors are also available.
