These connectors utilize the finest materials, which, along with precision manufacturing and rigid quality control, assure ITT Cannon customers of the finest quality connectors. The MS A & B product line has environmentally safe green and black zinc alloy plating. The Black zinc plating is RoHS complaint. The plating is a high quality, uniform finish. The contact, which are preloaded in the insulator, have been redesigned such that the solder cups remain in the proper orientation and will not rotate during wiring termination. The contacts are machined for strength and durability and plated with silver. The Cannon MS A&B design meets the performance requirements of the MIL-C-5015. The product is available in all the popular sizes and configurations available in Class A (solid end bell) and Class B (split end bell) versions. Applications: • Industrial Controls • Test Equipment • Traffic Signals • Bus Systems Product Features and Benefits • High strength aluminum alloy connector • Threaded coupling • High strength plastic insulators • Product is tooled and available in 50 insert patterns • Environmentally safe shell finishes • Machined contacts • Protected against corrosion • Low cost • High quality plating finish • UL recognized Performance Specifications Temperature Range: Current Rating: Durability: Wire Accommodation: No. of Contacts: Termination: –55°C to 125°C (-67°F to 257°F) 13 A to 150 A* 500 mating cycles min. 0 to 20 AWG* 2 to 48 Solder *Depending on contact size.

CA/MS 3100A receptacles mate with CA/MS 3106 and 3108 plugs. A Circular 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 receptacles 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 connectors. 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 connectors.
