Molex CP-6.5 Wire-to-Board Connector System is a foolproof interconnect system that provides quick, easy identification of mated pairs in wire-to-board applications. The 6.50mm wire-to-board receptacles and PCB headers have color-coded housings to differentiate mating possibilities. Connectors with mismatched colors do not mate. Unique keying features within each header and receptacle housing prevent the entry of the receptacle into the header when mismated. A positive lock feature produces an audible click when fully mated.
