0.087'' Tin-Plated Semi-Rigid Coaxial Cable 50 Ohm SR-086C-TP for Naval Electronic
The SR-086C-TP is a 0.086 inch (2.2mm) non-magnetic semi rigid coaxial cable featuring a silver-plated copper inner conductor and a tin-plated copper outer shield. Unlike standard semi-rigid cables that use copper clad steel conductors, this cable contains zero ferrous materials throughout. This unique combination serves dual purposes: the non-magnetic construction makes it suitable for MRI systems and quantum cryostats, while the tin-plated shield provides exceptional corrosion resistance for marine and coastal installations where these sensitive instruments are increasingly deployed. The PTFE dielectric delivers 70% velocity of propagation with 29 pF/ft capacitance and 50 Ohm impedance. With 61 GHz effective frequency, superior shielding effectiveness, and full RoHS compliance, this cable meets the demands of next-generation offshore MRI research vessels, coastal quantum computing facilities, and marine research laboratories.

Offshore MRI research vessels – Oceanographic research ships equipped with mobile MRI systems for marine life studies require both non-magnetic cabling for image quality and corrosion resistance for salt spray exposure. The SR-086C-TP enables high-field imaging at sea without image artifacts or cable degradation.
-
Coastal quantum computing facilities – Quantum research centers located in coastal regions face dual challenges: non-magnetic requirements for qubit coherence and corrosion protection from salt-laden air. This semi-rigid coaxial cable addresses both requirements in a single solution.
-
Marine biology imaging laboratories – Coastal research stations studying marine specimens using MRI and NMR techniques need non magnetic cabling that withstands humid, salty conditions without replacement.
-
Underwater communication test fixtures – Test equipment for underwater RF communication systems deployed in coastal test facilities requires non magnetic materials to avoid influencing measurements, plus corrosion resistance for the marine environment.

Floating laboratory platforms – Oceanographic buoys and floating instrument platforms require non magnetic RF cabling that can survive years of continuous marine exposure without replacement.
Q: How is this semi-rigid coaxial cable different from standard SR-086-TP?
A: Standard SR-086-TP uses an SCCS (silver plated copper clad steel) center conductor which contains steel and is magnetic. SR-086C-TP uses a solid silver plated copper center conductor with zero ferrous content, making it non magnetic while retaining the tin-plated shield for corrosion resistance.
Q: Why would I need non-magnetic semi-rigid coaxial cable in a marine environment?
A: Increasingly, sensitive scientific equipment is deployed in marine settings: MRI systems on research vessels, quantum sensors on naval ships, and NMR spectrometers in coastal laboratories. These applications require both non-magnetic materials for accurate measurements and corrosion resistance for survival in salt spray.
Q: Is the tin plating on the shield just for corrosion resistance?
A: Yes. The tin plating serves as a protective barrier against salt spray and humidity while the underlying copper tube provides the RF shielding and non-magnetic properties. The tin layer does not affect the cable's magnetic characteristics.
Q: What connectors are recommended for exposed marine installations?
A: For direct outdoor exposure, we recommend IP67 N-Type or IP68 TNC connectors with passivated stainless steel bodies. These provide weather-sealing while maintaining non-magnetic properties.
Q: What is the minimum order quantity?
A: 10 meters minimum for cable, with custom assembly quantities negotiable.
Q: How long will this semi-rigid coaxial cable last in marine environments?
A: The tin plated shield typically provides 5-8x longer service life than bare copper in salt spray conditions, with actual longevity depending on specific exposure levels.
