Functioning as a high-reliability physical layer media, this shielded twisted-pair component establishes deterministic token-passing pathways between central programmable logic controllers, decentralized input\/output platforms, variable speed drives, and operator interface terminals across manufacturing automation zones. Commonly referred to in industrial environments as the \u003cstrong\u003eBlue Hose\u003c\/strong\u003e, the cable is designed to provide stable transmission characteristics over long distances without data degradation.\u003c\/p\u003e\n\u003cp\u003eThe inner construction contains two twenty-gauge stranded tinned copper conductors insulated with high-density polyethylene, color-coded in clear and blue. To achieve rigorous noise rejection margins inside harsh industrial electromagnetic fields, the conductors are enveloped by an overall Beldfoil aluminum-polyester shield providing 100% coverage, supplemented by a 55% tinned copper braided shield and an integrated 20 AWG tinned copper drain wire. This industrial infrastructure component is standard across automotive assembly plants, automated sortation warehouses, process batching lines, and large-scale plant systems requiring highly reliable peer-to-peer processor interlocking and remote programming execution.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSpecialized twinaxial configuration optimized for Allen-Bradley Data Highway Plus and Remote I\/O networks.\u003c\/li\u003e\n\u003cli\u003eDual-layer shielding incorporating 100% Beldfoil tape alongside a 55% tinned copper braid for comprehensive EMI\/RFI isolation.\u003c\/li\u003e\n\u003cli\u003eDistinctive, high-visibility blue PVC outer jacket providing robust sunlight and oil resistance.\u003c\/li\u003e\n\u003cli\u003eIndustrial 78-ohm nominal characteristic impedance designed to match standard station connectors and termination resistors.\u003c\/li\u003e\n\u003cli\u003eSupport for long-distance network trunks spanning up to 10000 feet depending on network transmission speeds.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMulti-node Data Highway Plus (DH+) processor-to-processor interconnect networks.\u003c\/li\u003e\n\u003cli\u003eSLC 500 and PLC-5 distributed Remote I\/O (RIO) chassis communication links.\u003c\/li\u003e\n\u003cli\u003eControl cabinet trunk line wiring and inter-panel network drops.\u003c\/li\u003e\n\u003cli\u003eUnconditioned industrial environments requiring sunlight-resistant, long-run communication media.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer\u003c\/td\u003e\n\u003ctd\u003eRockwell Automation \/ Allen-Bradley\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eData Highway \/ Remote I\/O\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003e1770-CD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCable Type\u003c\/td\u003e\n\u003ctd\u003eShielded Twinaxial (Blue Hose)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Pairs\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Conductors\u003c\/td\u003e\n\u003ctd\u003e2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConductor Gauge\u003c\/td\u003e\n\u003ctd\u003e20 AWG\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConductor Stranding\u003c\/td\u003e\n\u003ctd\u003e7 x 28\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConductor Material\u003c\/td\u003e\n\u003ctd\u003eTC - Tinned Copper\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInsulation Material\u003c\/td\u003e\n\u003ctd\u003ePE - Polyethylene\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInsulation Color Code\u003c\/td\u003e\n\u003ctd\u003eClear \u0026amp; Blue\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInner Shield Type\u003c\/td\u003e\n\u003ctd\u003eBeldfoil Aluminum Foil-Polyester Tape (100% Coverage)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Shield Type\u003c\/td\u003e\n\u003ctd\u003eTC - Tinned Copper Braid (55% Coverage)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDrain Wire Gauge\u003c\/td\u003e\n\u003ctd\u003e20 AWG (7 x 28 stranding, tinned copper)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eJacket Material\u003c\/td\u003e\n\u003ctd\u003ePVC - Polyvinyl Chloride (Sunlight Resistant)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNominal Cable Outer Diameter\u003c\/td\u003e\n\u003ctd\u003e0.238 inches (6.05 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNominal Characteristic Impedance\u003c\/td\u003e\n\u003ctd\u003e78 ohms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNominal Conductor DC Resistance\u003c\/td\u003e\n\u003ctd\u003e9.5 ohms \/ 1000 feet at 20 Celsius\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNominal Outer Shield DC Resistance\u003c\/td\u003e\n\u003ctd\u003e4.1 ohms \/ 1000 feet at 20 Celsius\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNom.
