Waterproof Connectors MR Cannon's MR waterproof connectors, designed to meet the requirements of MIL-C-5015, withstand conditions involving mud, ice, and water. They are particularly suited for missile ground support equip- ment, radar installations, heavy construction in- stallations, and outdoor applications involving rapid transit, radie/tv stations, and marine equipment. Maximum resistance to severe environmental con- ditions is assured by an O-ring seal around the entry which provides a cable strain relief as well. When properly terminated to a jacketed cable, a mated pair of MR connectors can be immersed in depths of 150 feet in fresh water. For other immersion media consult factory. The MR connector series is supplied with Mit-C-5015 resilient insulators and solder pot con- tacts. For crimp type contacts refer to the ordering information below. MS contact arrangements, cou- MIL-C-5015. Simple maintenance under severe conditions is possible with a convenient, long, knurled coupling nut and endbell that can be easily removed by standard open end wrenches. Dust caps have attached bead chains to prevent kinking. Operating temperature range of connectors 55C ( 67F) to 125C (257F). The upper temperature is the maximum internal hot spot temperature resulting from any combination of electrical load mated insert faces, and a gland seal at the cable pling threads, and sizes are standard to and ambient temperature.
