1 ircular onnectors MR 4 Series onnectors General Information high density (.080 [2.0] contact centers), lightweight, subminiature, cylindrical connector series featuring crimp contacts and fingertip, push-pull, quick disconnect coupling. This series conforms to the applicable performance requirements of MIL and is available in unsealed, environmentally sealed, and hermetic types. large assortment in insert arrangements accommodating WG 12 through 2 gauge wire and miniature coaxial cables is available for the design engineer s choice. The contacts are retained by shoulder entrapment and can be crimped with the standard M22520 tools, using appropriate locators. This proven series of connectors has a long history of outstanding performance on many military and aerospace programs. MR 4 Series onnectors are ideal for applications where high performance must be achieved at low cost. Materials and Finishes Service and Performance ata I. Electrical Electrical Ratings MR 4 Series onnector housings and quick disconnect couplings are machined from bar stock aluminum to combine maximum strength with minimum weight. Threaded couplings are machined from nonmagnetic, stainless steel bar stock for durability of the coupling threads. ontacts are manufactured from high conductivity copper alloys which have been selected for low contact resistance over the operating range of the urrent Ratingielectric Working Voltage ontact mperes, Withstanding Sea 70,000 ft.
