Molex 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.
Molex Reflow Process Compatible (RPC) headers are available in both signal and power applications and handle up to 260°C solder temperature. The signal application KK 254 connectors deliver up to 5A and 250V per circuit in a 2.54mm centerline pitch. The KK 396 connectors deliver 13A and 600V per circuit in a 3.96mm centerline pitch.
