0.034" Non-Magnetic Semi-Rigid Coax Cable 50 Ohms UT-034C Alternative VNA Test Cable

The SR-034C is a precision non-magnetic semi-rigid coax cable engineered as a direct UT-034C alternative for applications where ferrous materials cannot be tolerated. Maintaining identical 0.034 inch (0.86mm) outer diameter and 50 Ohm impedance, this cable uses a silver-plated copper center conductor rather than copper-clad steel, ensuring zero magnetic susceptibility throughout the construction. The seamless copper tube outer conductor delivers 100% RF shielding with effectiveness exceeding 120 dB, eliminating signal leakage in sensitive multi-channel arrays. The PTFE dielectric maintains 70% velocity of propagation with 95.2 pF/m capacitance, while the 2100V RMS voltage rating supports high power RF chains. With cutoff frequency extending to 155 GHz, this non-magnetic coax meets the demanding requirements of 7T MRI receive coils, quantum computing cryostats, and precision measurement systems where even little ferrous contamination compromises performance.
