MIL-C-5015 Connectors MS-E/F/R/ER ITT Cannon is the foremost manufacturer of MS and MS type connectors with the widest range of connector styles, sizes and variations in the indus- try. These connectors utilize the finest materials, which, along with precision manufacturing and rigid quality control, assure ITT Cannon customers of the POTTING ER CONNECTORS (Solder Contact finest quality connectors.

Both the MS-F and MS-R have 0 rings to supplement the interfacial seal. Shells are alumi- num alloy. Contacts are siliver plated copper alloy. The F80 modification (crimp contact termination) is ACCESSORIES available in E, R, F and BFR styles with resilient Accessories to fit MS connectors include junction insulators. shells, protective caps, dummy or stowage recepta- cles, cable clamps, telescoping bushings. How to Order In the latest revision of MIL-C-5015, a new class of CA 3106 R 20 - 27 P W * environment-resistant connectors was added. This MS 3106 R 20 - 27 P W - new class F connector supersedes the previous PREFIX class E connector. The MS3106F is identical to the MS3106E except that the MS3106F has an0 SHELL STYLE ring under the coupling nut.
