KK Connectors

Molex KK Interconnection System consists of connectors that form the building block for creating thousands of different configurations. This system offers polarization features that ensure correct mating. The system incorporates offset header entry holes that provide +180°C polarization and allows both power and signal to carry through the same housing. This connector system also enables loading with optional polarization keys and pegs that ensure the one-way mating of headers and housings. Molex KK Interconnection System comes with customizable KK headers that offer more polarization options and design configurations. These include headers with voided pins, customized pin lengths, kinked PC tails, and varying tin or gold plating options.
