CRYOGENIC SEMI RIGID CABLES
In cryogenic systems, the coaxial cable serves not only as a signal carrier but also as a thermal bridge. This page helps you quickly identify materials and semi-rigid cable types—from stainless steel to CuNi and NbTi.
Anyone planning a system for low temperatures knows that the biggest challenge is often not the signal itself, but the heat input through the cables.
A cryogenic semi-rigid cable must therefore meet two conflicting requirements:
- the lowest possible thermal conductivity
- while maintaining sufficient electrical performance
The choice of the right material determines the heat load, attenuation, mechanical stability, and operational reliability.

Which Cryogenic Semi Rigid Cable is The Right Choice?
- Stainless steel Semi Rigid: Applications where heat input is more important than minimal attenuation
- NbTi Semi Rigid: Highly sensitive applications, with a focus on minimal heat input and the lowest possible attenuation
- SS-SSSP Semi Rigid: For high-frequency applications where the skin effect can be utilized
Which cryogenic semi-rigid cable is right for your application?
Selecting a cryogenic coaxial cable always involves balancing attenuation, thermal load, installation space, and signal integrity. The following table provides an initial guide to typical cable types for applications ranging from high-density integration to critical signal paths in the millikelvin range.
