In environments shaped by strong magnetic fields, even small material choices matter, prompting new approaches to compact RF connectivity for sensitive systems.
Amphenol RF has introduced additional non magnetic SMPM connector configurations engineered with non ferrous materials for use in magnetic field environments. The expansion addresses applications where even minor magnetic interference can influence precision instrumentation and RF signal behavior.
In environments such as MRI systems and quantum computing platforms, components are routinely exposed to strong magnetic fields. Under these conditions, material composition plays a critical role in overall system stability. The newly introduced SMPM configurations are designed for use in such settings, as well as in advanced instrumentation equipment where controlled and consistent RF transmission is required. The connectors are also suited for medical technologies including magnetic resonance angiography MRA, MRI scanners, medical imaging components, and specialized surgical instrumentation, where signal consistency and material selection remain key design considerations.
The SMPM interface offers a compact footprint, allowing integration into space constrained layouts and densely populated boards. This form factor supports board to board connectivity in modular system architectures. The connectors are available in smooth bore and full detent configurations and are compatible with existing non magnetic bullet adapters, enabling a complete board to board solution within non magnetic system designs.
Construction includes a gold plated beryllium copper body and contact paired with a PTFE insulator. These materials are selected to support electrical conductivity while maintaining non magnetic characteristics required for operation in magnetic field environments.
The additions join an existing range of non magnetic RF solutions that includes MCX, MMCX, SMB, and SMP options, extending available interconnect choices for systems operating in magnetically sensitive conditions.
