An engineer who's designed cables for FANUC or KUKA robotic arms will look at a surgical robot cable spec and assume it's a simpler problem—shorter cable, lower power, smaller forces. That assumption gets expensive quickly. The flex life number might even be lower than an…

Can you put a coaxial cable inside an MRI scanner without creating artifacts, heating tissue, or turning the cable into a projectile? The answer is yes—but only if you understand exactly which materials, geometries, and construction techniques make a cable MRI-compatible versus MRI-dangerous. And the…

Last year, a medical device startup came to us with what seemed like a simple request: "We need a cable assembly for our single-use bronchoscope. We've been using the same design as our reusable prototype—just need to cost it down for disposable volumes." They were…

The TDR trace on channel 47 was off. Not by much—about 12 picoseconds longer than the mean of the other 127 channels in the bundle. That's 12 trillionths of a second. On the screen it looked like a tiny blip, barely outside the ±1% tolerance…

Most engineers assume that the lowest dielectric constant always wins. It makes intuitive sense—lower Dk means higher velocity of propagation, lower capacitance, and wider bandwidth. So ePTFE with its Dk of 1.3–1.7 should be the obvious choice over FEP (Dk 2.15) or PFA (Dk 2.06)…

0.064 mm. That's the individual strand diameter of a 42 AWG 7-strand micro coaxial conductor—roughly the width of a human hair. Drop to 46 AWG and each strand shrinks to about 0.040 mm. That 0.024 mm difference doesn't sound like much, but it changes everything:…

Pick the wrong NDT coaxial cable and you won't know it until you're staring at a noisy A-scan 40 feet up on scaffolding—at which point swapping cables means climbing down, walking back to the truck, and losing half an hour of inspection time. It's not…

Last year, a medical device startup came to us after their cable supplier—an excellent ISO 9001-certified shop with 15 years of aerospace experience—failed their first OEM qualification audit. The cables were good. The testing was solid. But when the auditor asked for a design history…

A 46 AWG coaxial cable going into an IVUS catheter and a 42 AWG coaxial cable going into a cardiac ultrasound probe might look like close relatives on a datasheet. Both carry ultrasound signals. Both demand controlled impedance. Both use micro coaxial cable at their…

MRI, CT, and PET scanners each impose unique and extreme demands on cable assemblies — demands fundamentally different from other medical imaging cables. MRI generates 1.5–7 Tesla magnetic fields plus radiofrequency pulses at 64–300 MHz. Any ferromagnetic material becomes a projectile hazard. Any long conductor…

Non-destructive testing (NDT) ultrasound uses the same core micro coaxial technology as medical imaging — individually shielded 50 Ω elements with ePTFE dielectric and silver-plated conductors — but in environments medical cables never see: refineries at 85°C ambient, nuclear plant containment zones, offshore platform decks…

The 256-core coaxial cable bundle is the most demanding standard configuration in micro coaxial manufacturing. 256 individually shielded 50 Ω elements — each with its own foil and braid shielding — must be precisely arranged in concentric layers, phase-matched within ±1% propagation delay, and enclosed…

44 AWG micro coaxial cable bridges the gap between the industry-standard 42 AWG (0.48 mm) and catheter-grade 46 AWG (0.30 mm). At 0.38 mm OD, 44 AWG delivers approximately 20% smaller bundle diameter than 42 AWG at equivalent channel count — the difference that enables…

42 AWG micro coaxial cable is the workhorse of the micro coaxial industry. At 0.48 mm OD with ePTFE dielectric, it delivers the optimal balance of signal performance, bundle density, mechanical durability, and cost that has made it the default choice for 128–256 channel ultrasound…

36 AWG coaxial cable is the crossover point between standard miniature coax (RG-174 at 2.8 mm / RG-178 at 1.8 mm) and ultra-fine micro coaxial grades (42–50 AWG at 0.19–0.48 mm). At 36 AWG, the silver-plated conductor measures 0.127 mm, producing 0.75 mm finished cable…
