Space-Grade D-Subminiature Backshells and Accessory Hardware

Space-Grade D-Subminiature Backshells and Accessory Hardware

MIL-DTL-24308

D-Sub EMI backshells are used to ground cable shields for electromagnetic compatibility, and to provide strain relief and mechanical protection of wire-to-connector terminations. These backshells are made out of aluminum alloy or composite thermoplastic. Electroless nickel is the most widely used finish. These backshells are compatible with industry-standard metal shell M24308 type connectors.

Glenair's Improved-Design Two-Piece Backshells, with IS-Sommer Cross-Reference

IS-Sommer rectangular connector accessories utilize a two-piece design with a separable band platform and loose/removable hardware. Glenair design improvements to this standard deliver serious performance in space and other high-performance application environments. Importantly, Glenair backshells of this type feature only captive hardware. Even when the two-piece backshell is split for assembly around the wired connector, Glenair hardware remains captive to the backshell body, eliminating the risk of FOD in sensitive space applications.

The architecture of the Glenair split shell design incorporates a sliding tongue-and-groove for superior EMC performance and ease of use. Also, unlike competitor solutions, the separable cable entry piece is captive when the backshell is assembled, and stays in position with an anti-rotation feature.

Glenair split-shell cable-clamp backshells likewise feature all captive hardware and a low-profile saddle-bar cable clamp. In general, the Glenair design facilitates faster, safer, trouble-free cable assembly.
