Connectors Suitable for Transportation Applications
Building on the success of its CMC connection system, Molex Incorporated introduces its second generation sealed, hybrid, high-density and modular connector system. The CMX family uses a new CTX terminal system with a fully protected seal to deliver the ultimate in sealing performance. The CMX connector system is suitable for transportation powertrain applications, such as those found in engine control units, automatic gearboxes, suspension controllers and electrical parking brakes.
"Based on our 10 years of experience with the CMC product line, the next-generation CMX connection system offers significant improvements in product performance while remaining cost competitive," says Selvan Wilhelm, global product manager, Molex. "The unique feature for all new CMX connectors is the sophisticated design of the interfacial seal protection, which ensures the connector remains protected before mating, and during mating and unmating operations."
The first two circuit sizes of the CMX family, which meet the demands of the transportation market, is a compact 5-row 55-circuit CMX connector and a 5-row 65-circuit CMX connector. Further circuit sizes to extend the family are in development. Both CMX connectors support low and medium current using .635 mm (.025") and 1.50 mm (.059") CTX terminals. The new matte seal is designed for the high performing sealing function of the CTX terminals and can be used with ISO and JASO wires. The CTX terminal system features a clean-body type design that performs well in harsh environments, while serving low, medium and high current applications. The use of high conductivity copper alloy allows excellent stress relaxation and current carrying properties.The rear seal cover, which can be molded with breakable dummy plugs for the CTX terminal cavities, helps to reduce cycle time and applied costs for harness manufacturers. It also allows customers more flexibility for unused cavities.
