Multicoax systems for cryogenic applications


Comprehensive MXP 2×8 ganged multicoax cabling solution for room temperature and cryogenic applications


A seamlessly integrated multicoax cabling system engineered for exceptional channel density, supporting up to 192 channels with an ISO flange. The system is designed to operate reliably across the entire thermal range, from standard room temperature down to the millikelvin (mK) levels in the mixing chamber.


  • Hermetically sealed transitions maintain vacuum integrity and deliver excellent thermal isolation
  • Precision cable assemblies are tailored to meet specific customer requirements at every thermal stage
  • The portfolio includes flexible and semi-rigid assemblies, attenuator blocks, and a PCB connector to ensure full system compatibility
  • Components are available in Copper Telluride and Copper Beryllium materials
  • Semi-rigid cables are offered in Cupronickel, Copper Beryllium, Stainless Steel, and Niobium Titanium
  • Flexible cabling is provided using the versatile Multiflex 53-02 cable
