Cannon MJK Series Connectors


Cannon’s MKJ Miniature Circular Connectors enable high-speed data, power and signal transmission in a wide range of technology-driven applications and platforms. At less than half the size and weight of standard military-grade interconnects, MKJ offers highly engineered design, performance and reliability, but in a much smaller design package. Our MKJ Connector Series also comes with rear accessory threads or integral band platform for direct attachment of cable shield and overmold. Choose from five different MKJ connectors in a variety of coupling options: UN Thread, Double Start, Triple Start, Bayonet and Cannon Breakaway.
