Molex KK® Interconnection System

Now Available - Reflow Process Compatible (RPC) headers are now available in both signal and power applications and can handle solder temperatures up to 260ºC. Signal application KK 254 connectors delivers up to 5.0A and 250V per circuit in a 2.54mm centerline pitch. Power application KK 396 connectors deliver 13.0A and 600V per circuit in a 3.96mm centerline pitch.

Molex KK® Interconnection System
offers many polarization features to ensure correct mating in an application. The KK® Interconnection System has offset header entry holes, which provide 180º polarization, allowing both power and signal to carry through the same housing, and can also be loaded with optional polarization keys and pegs, to help ensure that the headers and housings only mate one way. Customizable KK headers allow for more polarization options and design configurations, such as headers with voided pins, customized pin lengths, kinked PC tails, and varying tin or gold plating options, providing application design flexibility. The Molex KK® Interconnection System of "building block" connectors can create thousands of different configurations, allowing each user to build a system precisely suited for any application on centers from 2.50 to 5.08mm with a maximum current of 13.0A per circuit while handling up to 600V.
