High-density connection system targets automotive and transportation applications

Molex's CMC product line has expanded with the introduction of a 154-circuit header in compliant-pin mount and 32- and 112-circuit solder-mount headers. 

Designed to perform in high-conductivity applications and harsh environments, CMC is an industry standard interface used in automotive and transportation powertrain applications, including ECUs (engine control units), automatic gearboxes, suspension controllers and electric parking brakes.

The new 154-circuit, three-pocket, right-angle header with compliant-pin terminals improves productivity and reduces assembly costs by enabling a solder-free process, as opposed to conventional press-fit type mounting processes.  The 154-circuit header features 120 x 0.635mm (.025") signal pins, 24 x 1.50mm (.059") terminals and 10 x 2.80mm (.110") power pins, supporting high currents in applications such as large ECUs.  The high-end design of the integral guiding plate protects the 5 terminal rows and ensures positioning, while being able to withstand high-vibration levels up to 10G.  Intended for heavy-duty agricultural equipment applications, the 154-circuit connection system performs up to 50 mating cycles for mating and unmating of multiple ECUs on different applications.

The new 32-circuit, single-pocket, right-angle header, solder-mount terminals are designed for smaller powertrain applications, in addition to hydraulic and electronic suspension controllers.  The 112-circuit, three-pocket, right-angle header, which also features solder-mount terminals, is designed for any ECU application requiring a higher number of circuits.  Both the 32- and 112-circuit headers are constructed of hydrolytically stable, high flammability UL 94V-0 plastic material, suitable for epoxy adhesion, which make them well-suited for sealed applications.

The 154-circuit header is available with optional combinations of circuits based on customer requirements.  The 32- and 112-circuit headers follow the same standard cut-out shape as Molex 48- (500762) and 80-circuit (502225) headers.  Various color codings allow modularity and easy mating of the CMC headers and connectors.
