0.086" Semi-Rigid Coaxial Cable Non-Magnetic 50 Ohm UT‑085C Alternative Microwave Cable

SR‑086C semi‑rigid coaxial cable is a 0.086" diameter, 50‑ohm, non‑magnetic microwave cable engineered for applications where low magnetic signature and stable RF performance are critical. It uses a non‑magnetic silver plated copper center conductor and solid copper tube outer conductor with PTFE dielectric, delivering low loss, excellent shielding, and tightly controlled 50Ω impedance across a broad frequency range. SR‑086C is ideal as a non‑magnetic alternative to UT‑085‑type semi‑rigid cables in MRI, NMR, precision instrumentation, and other magnet‑sensitive systems. Its semi‑rigid construction allows accurate pre‑forming to tight bend radii while maintaining consistent phase and VSWR for high‑reliability assemblies.

• 0.086" (≈2.18 mm) 50‑ohm semi‑rigid non‑magnetic coax for RF and microwave applications.

• Non‑magnetic conductors and outer jacket to minimize magnetic interference and susceptibility.

• PTFE dielectric for low loss, stable electrical properties, and predictable phase performance.

• Wide operating frequency range suitable for high‑frequency microwave and test applications.

• Excellent shielding effectiveness for low leakage and high isolation between channels.

• Tight dimensional control for compatibility with common UT‑085 style connectors and layouts.

• Designed for harsh environments: wide operating temperature range and robust mechanical stability.

• Suitable for precision pre‑formed assemblies and high‑density RF modules.

• MRI and NMR systems where non‑magnetic components are mandatory to avoid image distortion.

• Precision lab and metrology equipment in strong magnetic fields or magnetically sensitive environments.

• High‑density RF and microwave modules requiring controlled routing and low magnetic signature.

• Aerospace, defense, and scientific instruments with strict EMC and magnetic cleanliness requirements.

• Custom pre‑formed semi‑rigid cable assemblies for production test fixtures and RF sub‑systems.

A: SR‑086C uses non‑magnetic silver plated copper conductor and copper tube outer conductor materials (no ferromagnetic alloys), so it exhibits negligible magnetic attraction and minimal influence on magnetic fields. This makes it suitable for MRI, NMR, and other magnet‑sensitive applications.

A: Yes, SR‑086C is designed to maintain similar 50‑ohm impedance, diameter, and RF performance characteristics as standard 0.086" semi‑rigid cables, while using non‑magnetic materials. Always review the detailed datasheet to confirm insertion loss, power handling, and maximum frequency for your design.

A: In many cases, yes. The 0.086" semi‑rigid form factor allows SR‑086C to fit footprints designed for UT‑085‑type cables, but you should check mechanical tolerances, connector compatibility, and bend paths before finalizing the replacement.

A: Non‑magnetic designs are typically optimized to keep insertion loss and power handling comparable to standard semi‑rigid cables of the same size. Exact ratings depend on the specific materials and construction, so consult the product specification for precise values.

A: The minimum formed bend radius is similar to other 0.086" semi‑rigid cables and is usually on the order of a few cable diameters. For reliable performance, follow the manufacturer’s recommended bend radius and use proper forming tools to avoid kinks and impedance changes.

A: Semi‑rigid PTFE‑based, non‑magnetic cables like SR‑086C are commonly used in vacuum and low‑temperature applications, thanks to their stable dielectric and solid metal construction. Always verify outgassing, temperature limits, and mechanical stress requirements against your system spec.

A: Yes. We accept OEM & ODM, buyers can order SR‑086C as straight lengths or as pre‑formed assemblies based on 2D drawings or 3D models. Providing exact lengths, bend angles, and connector types helps ensure repeatable routing and faster installation.

A: When requesting a quote, include: cable type (SR‑086C non‑magnetic), impedance, length, connector types and genders, operating frequency range, required VSWR or return loss, any special environmental requirements, and a drawing for pre‑formed shapes if needed.
