MKJ Series Overview
Versatility, performance and reliability in a miniaturized footprint,
enables unparalleled functionality.
Key Features
• Plugs and receptacles are environmentally sealed
for use in the harshest environments
• RoHS-compliant configurations
The MKJ family of miniature circular connectors provides
similar electrical and mechanical characteristics as larger
and heavier Military Standard Environmental connectors,
but in a smaller form factor. Bringing together a unique
combination of design, functionality and flexibility,
Cannon’s MKJ connectors excel in delivering proven and
reliable solutions that perform even in the harshest
environments. The MKJ series comes with rear accessory
threads or integral band platform for direct attachment of
cable shield and overmold.
Configuration
Coupling
• EMI Shielding - up to 40dB Attenuation,
100MHz to 1000MHz
• PCB mount jam nut for enhanced EMI and
vibration resistance performance
• Cable assemblies and application specific shell
configurations available
