MarKK, Molex’s next-generation KK® terminal, utilizes a spring-box design for enhanced
reliability across an extended temperature range
Molex’s MarKK (pronounced “Mark”) terminal is
the next-generation product in the KK terminal
offering. The new spring-box design provides a
high-force interface, assuring good contact over
broader temperatures. Designed to meet increasing
customer demands, MarKK provides the next level of
performance in the familiar KK terminal design.
proven KK system of “building block” connectors can
be used to create different configurations, allowing
each user to build a system that is precisely suited
to any application.
