CA/MS 3100A receptacles mate with CA/MS 3106 and 3108 plugs. CA/MS 3101A cable connecting receptacles are used for cable extension requirements where mounting provisions are unnecessary. CA/MS 3101A plugs mate with 3106A/B and 3108B connectors. Note: The D revision of MIL-C-5015 has changed the nomenclature of the 3101 from receptacle to plugs. CA/MS 3102A box mounted recepta- cles are used in junction boxes or as an integral part of equipment. CA/MS 3102A receptacles will mate with 3106 and 3108 plugs. CA/MS 3106A straight plug utilizes a solid endbell. The CA/MS 3106A mates with 3100, 3101, and 3102 connectors CA/MS 3106B is identical to the 3106A straight plug except it utilizes a split endbell. CA/MS 3106B mates with 3100, 3101, and 3102 connec- tors. CA/MS 3108B 90 angle plugs are used where there is limited space ad where wires must be brought at abrupt angles. This plug will mate with 3100, 3101, and 3102 connec- tors. Dimensions shown in inches (mm) Specifications and dimensions subject to change www.ittcannon.com A-73
