📋 Product Overview 產品概述
Individually shielded twisted pairs for critical instrumentation applications
The GEXOL®-331HF Shielded Pairs Instrumentation Cable is specifically engineered for precision signal transmission in demanding offshore and marine environments worldwide. Each twisted pair consists of Black-White color coded conductors with a bare tinned drain wire, individually shielded with polyester-backed aluminum foil tape providing 100% coverage for superior electromagnetic interference (EMI) protection. The cable features pair-to-pair isolation plus an overall shield, making it ideal for sensitive instrumentation circuits that require noise immunity. Available in configurations from 1 to 24 pairs in both 16 AWG and 14 AWG, this cable maintains circuit integrity during fire conditions while delivering exceptional signal quality. Blue jacket or stripe options are available to signify intrinsically safe (IS) circuits.
