FEATURES AND SPECIFICATIONS
3.96mm (.156”) Pitch
MarKK™ Crimp Terminal
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.
MarKK terminals are available in both pre-plate and
post-plate Tin versions, as well as post-plate select
Gold to ensure a broad selection of options. The
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.
The MarKK terminal is designed to be used with the
following crimp housings: KK Crimp Terminal Housings
Series 41695 and 6442. Tooling that utilizes the new
MarKK design is available, FineAdjust™ applicator part
number 63866-2000.

Features and Benefits
n Utilizes spring-box design and provides
high-force interface assuring good contact
over broader temperatures
n Head-and tail-carried design eliminates
customer’s need to monitor cutoff dimension
in application tooling
n High conductivity alloy allows increased current-
carrying capability; up to 13.5A per line (see
product specification for details) based on a
2-circuit system
n Four truly independent points of contact
assures a highly reliable interface
