3 core silicone cable-26 awg silicone wire PFA Insulation OD 4.0mm

Ultra-Flexible Micro-Signal Routing for Minimal Invasive Instruments

The 3 Core Medical Silicone Cable (Model with 26 AWG conductors) is explicitly engineered for micro-signal routing, low-voltage telemetry, and ultra-lightweight medical handpieces. By utilizing finer 26 Gauge wires insulated with heavy-duty PFA insulation, this specialized 3 core silicone cable dramatically increases structural suppleness while maintaining a tight, non-obtrusive outer diameter of just 4.0mm.

Perfectly optimized for dense, space-constrained clinical environments like compact diagnostic wands and reusable surgical electrodes, its effortless bending dynamics prevent hand fatigue for surgeons and medical operators during prolonged procedures. For massive multi-channel sensor layouts that require a scaled-up, high-density cluster, we also design a matching 32 core high temp silicone wire matrix incorporating 12 precisely twisted conductor pairs.

Advanced Material Science: High-Dielectric PFA Cores & Biocompatible Shell

The internal primary insulation of each wire core is extruded from premium PFA (Perfluoroalkoxy) fluoropolymer. PFA delivers exceptional dielectric strength, ultra-low capacitance, and complete chemical inertness, safeguarding the underlying micro-stranded copper lines against high voltage spikes and aggressive operating theatre disinfectants. The external protective sheath is custom-compounded from a biocompatible medical-grade vulcanized solid silicone rubber matrix, providing a velvety, friction-free tactile feel that glides easily over surgical drapes.

Our ultra-fine stranding structure guarantees that all internal multi-stranded conductors remain completely uncompromised after repeated chemical and autoclave steam sterilization processing cycles at 134°C. If your imaging or visualization tool operates within an even tighter geometric layout that demands extreme cross-section reduction, exploring our ultra-miniature 16 conductor 40 AWG medical silicone cable provides an advanced alternative managing 8 distinct twisted pairs inside a sub-3mm footprint.
