Molex CMC 28-Circuit Header and Receptacle

Molex CMC 28-Circuit High Current Header mates with the CMC 28-Circuit Receptacle and Female Power Connector to offer a space-saving wire-to-board solution for sealed transportation applications requiring up to 21A. This header uses the standard Molex CMC header cut-out shape and features a hybrid terminal combination with 5x CP 2.80mm, 18x CP 0.635mm, and 5x CP 1.50mm solder-mount terminals. The compact design of the Molex CMC 28-Circuit interface provides a space-saving solution for many sealed applications in transportation vehicles, particularly those with challenging space requirements such as motorcycle engine control modules.
