The ZION RG316D Dual-Core Overall Shielded Coaxial Cable is a high-performance RF cable assembly designed for multi-channel signal transmission in harsh and high-temperature environments.
Featuring two RG316D coaxial cores, each with silver-plated copper conductors, PTFE dielectric insulation, and dual-layer braided shielding, combined with an overall tinned copper braid and TPU outer sheath, this cable delivers excellent EMI suppression, thermal stability, and mechanical durability.
It is ideal for aerospace electronics, defense systems, RF modules, industrial instrumentation, and other applications requiring stable impedance, low VSWR, and superior shielding effectiveness.
■Key Features
