Product Description
Product description

The SR-086C-SP is a precision 0.087 inch (2.2mm) non-magnetic semi-rigid coaxial cable featuring silver plated copper inner conductor and silver plated copper shield throughout its construction. Unlike standard semi-rigid coax cables that use copper clad steel conductors, this cable contains zero ferrous materials. This complete elimination of magnetic materials makes it ideal for MRI systems, quantum computing cryostats, and precision instrumentation where magnetic interference cannot be tolerated. The PTFE dielectric provides 70% velocity of propagation with 29 pF/ft capacitance and 50 Ohm impedance. With 61 GHz effective frequency, >100 dB shielding effectiveness, and 173.8 dB/100ft attenuation at 50 GHz, this cable delivers reliable performance for demanding millimeter wave applications. Operating temperature range is -55°C to +125°C with full RoHS compliance.

  • Quantum computing cryostats – Control and readout lines in dilution refrigerator systems requiring non-magnetic materials to preserve qubit coherence times at millikelvin temperatures

  • Cryogenic device characterization – Low temperature measurement setups for superconducting electronics and quantum sensing applications

  • Medical device manufacturing – Test fixtures for MRI compatible electronics and implantable device qualification

  • Semiconductor research – Cryogenic probing stations and material characterization systems requiring magnetic free environments

  • Precision metrology – Reference standards and calibration fixtures for sensitive magnetic field measurements

  • Aerospace instrumentation – Magnetometer payloads and scientific instruments requiring zero magnetic interference

  • Particle accelerators – Beamline monitoring and RF pickup applications where magnetic materials disturb particle trajectories

  • Research laboratories – Custom experimental setups requiring non magnetic RF paths for sensitive measurements

  • Defense and aerospace – Electronic warfare systems and secure communication links where magnetic signature control is critical


FAQ

Q: What makes SR-086C-SP different from standard 0.086 semi-rigid coax cable?

A: The SR-086C-SP features a silver plated copper center conductor rather than copper clad steel, and a silver plated copper tube outer conductor with zero ferrous content throughout.

Q: What is the maximum frequency for this semi-rigid coax cable?

A: The SR-086C-SP has an effective frequency of 61 GHz with attenuation of 173.8 dB/100ft at 50 GHz. Higher order mode cutoff extends beyond this range for clean propagation.

Q: What connector options are available for custom assemblies?

A: We offer SMA (26 GHz), 2.92mm (40 GHz), 2.4mm (50 GHz), 1.85mm (65 GHz), and SMP connectors. Custom configurations available upon request.

Q: What is the minimum order quantity for custom assemblies?

A: 10 meters minimum for cable, with custom assembly quantities negotiable based on requirements.

Q: Is this cable suitable for cryogenic applications?

A: Yes. The all copper construction performs reliably at cryogenic temperatures down to 4K and below. The silver plated surfaces maintain conductivity at millikelvin temperatures.

Q: What documentation is available for non-magnetic verification?

A: Material certification and non-magnetic verification available upon request for MRI, quantum, and defense applications.
