As a critical peripheral in the TPNB (TotalPlant Network Bridge) environment, this CAT5e-grade interconnect is built to facilitate stable 100-BASE-T communication between controllers and network nodes. Unlike standard commercial patch cords, the 51305482-205 is manufactured with rigorous length tolerances and shielding to prevent signal timing jitter and electromagnetic interference. It provides the physical backbone necessary for high-availability process control, ensuring that secondary network paths remain synchronized and ready for instantaneous failover.\u003c\/p\u003e\n\u003ch3\u003eElectrical Benchmarks and Hardware Parameters\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eCable Length:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e5 Meters (±0.5% tolerance)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eStandard:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eCAT5e \/ 100-BASE-T Optimized\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eData Throughput:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e100 Mbps\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eConductor Construction:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e24 AWG Stranded Copper\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eImpedance Profile:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e100Ω ±15%\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eDC Resistance:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e≤9.38Ω per 100m\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eSignal Timing:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003ePropagation delay ≤548ns\/100m with ≤45ns\/100m delay skew\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eThermal Range:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e-20°C to +60°C (Operation) \/ -40°C to +75°C (Storage)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eVoltage Rating:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eUp to 30V AC\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eNet Weight:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e0.38 kg (Shipping weight 0.4 kg)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003ePackaging Dimensions:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e7 x 14 x 14.5 cm\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eManufacturing Origin:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eUSA\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eTariff Code:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e8537101190\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eIndustrial Control System Applications\u003c\/h3\u003e\n\u003cp\u003eThe 51305482-205 TPNB LAN B cable is primarily utilized in large-scale industrial infrastructures such as petrochemical plants, offshore platforms, and power generation facilities where redundant networking is mandatory. In a typical Experion PKS setup, this cable is dedicated to the \"B\" side of the Fault Tolerant Ethernet (FTE) or TPNB bridge, allowing for physical separation of redundant data paths to prevent simultaneous network failures. Its 24 AWG stranded core is designed to withstand the vibration and tight-radius routing common in high-density DCS cabinets. By maintaining strict electrical characteristics across its 5-meter span, it prevents the data collisions and packet loss that often plague lower-grade cabling in electrically noisy environments near high-voltage motor starters and variable frequency drives.\u003c\/p\u003e\n\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Why is this cable specifically designated as a \"LAN B\" cable?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: In Honeywell redundant architectures, cables are often color-coded or tagged to separate the primary (LAN A) and secondary (LAN B) networks. Using a designated LAN B cable like the 51305482-205 ensures that technicians maintain the correct topology during installation and maintenance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can this cable be used for PoE (Power over Ethernet) applications?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: While the 24 AWG copper construction can technically handle low-voltage power, this cable is specifically rated and certified for 100-BASE-T data signals in DCS environments with a maximum voltage rating of 30V AC.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Is the 5-meter length the only version available?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: The 51305482-205 refers specifically to the 5-meter variant. Honeywell produces other part numbers in this series for different lengths to ensure exact fitment within various cabinet sizes without excessive cable slack.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does this cable feature a specialized jacket for chemical resistance?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: The jacket is a ruggedized industrial grade designed for the temperature extremes found in plant environments (-20°C to +60°C) and provides standard resistance to the humidity and oils typically found in control room cabinets.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is the benefit of the low \"Delay Skew\" mentioned in the specs?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: Low delay skew ensures that data arriving across different wire pairs within the cable stays synchronized. This is vital for time-sensitive control protocols where even nanoseconds of misalignment can cause communication errors between controllers.\u003c\/p\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":45518938996909,"sku":"51305482-205","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0733\/1613\/9181\/files\/honeywell-51305482-205-tpnb-lan-b-cable-re0v1inr00n.jpg?v=1766982372","url":"https:\/\/www.maxwellplc.com\/products\/honeywell-51305482-205-tpnb-lan-b-100-base-t-ethernet-cable-5m","provider":"Maxwell PLC Ltd","version":"1.0","type":"link"}
