Molex's proven KK system of "building block" connectors can be used to create thousands of different configurations, thereby allowing each user to build a system that is precisely suited to any application on 2.50mm (.09"), 2.54 (.100"), 3.96 (.156") and 5.08mm (.200") centers.

The system offers interconnection in a number of modes; wire-to-board, board-to-board, both vertical and right angle, and board- or cable- to chassis. Features include a friction lock to secure connectors to wafer, polarizing wall or location pegs to assure correct assembly. Various methods of securely holding the connectors to a PC board are available. Headers are available in solid or breakaway, and housing termination can be crimp or IDT.

The Molex KK interconnection system can provide all the options necessary to complement PC board interconnection design requirements. For this reason, KK has become known as a versatile interconnecting system developed to meet the challenge of modularization.
