Non-Magnetic SMA Male to SMA Male Cable FM-141FL-NM Coax

Why It Matters

The cable’s non‑magnetic construction and high‑frequency capability enable reliable signal integrity in magnetically sensitive environments, a critical need for defense and aerospace systems where performance and rapid deployment are paramount.

Key Takeaways

• 50 Ω non‑magnetic SMA‑male to SMA‑male cable supports up to 18 GHz.
• Operates from –55 °C to 165 °C with VSWR ≤1.4:1.
• 0.375‑inch bend radius, 90 dB shielding, gold‑plated brass connectors.
• Quick‑ship inventory reduces lead times for defense and aerospace projects.
• Silver‑plated copper core and PTFE dielectric improve signal‑to‑noise ratio.

Pulse Analysis

Non‑magnetic coaxial cables have become essential in sectors where magnetic fields can corrupt high‑frequency signals. Traditional SMA assemblies use ferrous components that introduce distortion, especially in radar, satellite, and electronic warfare platforms. By eliminating magnetic materials, Fairview’s FMCA100381 preserves signal fidelity, delivering a higher signal‑to‑noise ratio and stable impedance across the 18 GHz band, which is increasingly demanded by modern phased‑array and 5G test rigs.

The FMCA100381’s technical specifications address several pain points for system integrators. A silver‑plated copper conductor paired with PTFE dielectric minimizes loss while the 90 dB shielding attenuates external interference. Its 0.375‑inch bend radius and robust brass‑gold connectors allow tight routing in cramped enclosures without compromising VSWR, which stays at or below 1.4:1 even at extreme temperatures ranging from –55 °C to 165 °C. These attributes make the cable suitable for aerospace avionics, defense communication links, and high‑precision laboratory measurements where durability and repeatable performance are non‑negotiable.

Beyond performance, the product’s fast‑ship availability reshapes supply‑chain dynamics for mission‑critical projects. With a stocked inventory, engineers can bypass the long lead times typical of custom‑order coax, accelerating prototype cycles and reducing time‑to‑field. As defense budgets prioritize rapid modernization and commercial aerospace pushes toward higher‑frequency connectivity, demand for ready‑to‑deploy, non‑magnetic RF components is set to rise. Fairview’s emphasis on inventory readiness positions it to capture a growing share of the market, while the broader industry may see increased pressure to standardize on magnet‑free designs for future high‑frequency applications.
