Circuit headers boast press-fit terminals

Molex Inc. has extended its CMC product portfolio with the release of a 154-circuit header, and 32- and 112-circuit solder-mount headers. The connection system is designed to perform in high-conductivity applications and harsh environments such as automotive and transportation powertrain applications. These include engine control units (ECUs), automatic gearboxes, suspension controllers and electric parking brakes.

The 154-circuit, three-pocket, right-angle header with compliant-pin terminals improves productivity and reduces assembly costs via solder-free process, as opposed to conventional press-fit type mounting, stated Molex. It features 120 x 0.635mm signal pins, 24 x 1.50mm terminals and 10 x 2.80mm power pins, supporting high currents in applications such as large ECUs.

The hybrid connection system targets high-vibration automotive powertrain applications.

According to the company, the design of the integral guiding plate protects the five terminal rows and ensures positioning, while being able to withstand high-vibration levels up to 10G. Ideal 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 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 ECU applications requiring a higher number of circuits. Both devices are constructed of hydrolytically stable, high flammability UL 94V-0 plastic material, suitable for epoxy adhesion, making them ideal 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.
