NON-MAGNETIC RF CONNECTORS
Introduction
Johnson’s Non-Magnetic Connector Additions Offer Solutions to MR Imaging Technology
Johnson, a product line of Cinch Connectivity Solutions, has expanded the connector product groups in its popular line of Non-Magnetic
RF coaxial connectors and cable assemblies.
MCX and MMCX micro-miniature connectors have been added to satisfy the needs of the RF coil manufacturers that are building smaller
coils for MRI equipment. Customized flex coils and array coils can image smaller parts of the body such as wrists, feet, hands and other
appendages.
The Non-Magnetic MCX and MMCX is the perfect micro-miniature connector for small multichannel coil packages as they provide a
positive snap-on coupling design with high mating cycles for rugged, high density connectivity.
The Type N Non-Magnetic connector provides a perfect RF solution for high Tesla fields considered for future designs. These deep tissue
MR images will require the rugged interface of the N connector as well as the tri-alloy plating to eliminate inter-modulation issues.
All the connectors in Johnson’s Non-Magnetic line are made from high purity copper alloys assuring no ferrous materials are in the
connectors manufactured. Cinch Connectivity Solutions continues to work with our customers to develop new solutions as the MR
industry transitions to high-end field applications and improved resolution at greater physical depths within the body.
Products are offered through authorized distributors and international sales channels including a direct sales force and a network of
manufacturers’ representatives. For more information, please call (800) 247-8256.
