Cannon MKJ Series: Reduction in weight and
size without loss of reliability
The MKJ family of mini-circular connectors provides similar electrical
and mechanical characteristics as larger and heavier Military Standard
Environmental connectors.
ITT Cannon continues its tradition of innovation with the
MKJ line of miniature circular connectors. MKJ products
tackle your matrix of harsh environment applications.
These connectors offer three coupling methods (threaded,
bayonet and breakaway) in a highly engineered design
with reduced weight by 71% and size by 52% without
sacrificing the environmental performance or reliability.*
Bringing together a unique combination of design,
functionality and flexibility, the MKJ excels in delivering
a product for a broad variety of harsh environment
applications. The MKJ series comes with rear accessory
threads or integral band platform for direct attachment
of cable shield and overmold. MKJ provides unparalleled
functionality for numerous applications across multiple
markets including Industrial, Defense and Aerospace.
