D-Sub connector housing Backshells

EMC-shieldedmetalaluminum

Overview
D-subminiature (D-sub) backshells provide enhanced protection and increased functionality to a connector system. They help ensure optimal performance and reliability for D-sub connectors by offering mechanical protection, cable management and electromagnetic compatibility features.

Benefits

• Strain relief for cable terminations
• Shielding termination points for improved EMI/RFI protection
• Positive locking mechanisms and coupling features
• Improved durability and mechanical protection of connector interfaces
• Options for top or side entry, tie-wraps, cable clamps and other cable retention methods

Available constructions and materials

• Precision machined lightweight aluminum two-piece backshells (A / AS / AL Series)
• Precision machined banded backshells (AP / AK / AW Series)
• Precision machined one-piece banded backshells (XP / XW / XK / XR / XS Series)
• Precision machined one-piece threaded backshells, aluminum or stainless steel (X3P / X3W Series)
• Electromagnetically compatible low-profile machined backshells with tie-wrap (EL Series)
• Zinc die-cast backshells with top or side entry (CT / CS / DT / DS Series)

Applications

• Industrial and commercial D-sub connector systems
• Mil/Aero environments (variants and accessories suitable for military/aerospace use)
• Spaceflight and other high-reliability applications (dedicated space-focused backshell options and literature exist)

Documentation and selection resources
Multiple technical brochures and catalogs are referenced on the product series page for selecting the correct backshell style, material and accessory options. These cover subjects such as accessories (jackscrews, IP sealing), lightweight aluminum machined backshells, banded and threaded backshell families, low-profile EMI-compatible designs and space-rated product guides.
