BELDEN 3106A 1 PAIR MODBUS
Belden 3106A is an advanced industrial communication cable designed for RS-485 and Modbus networks that require both a data signal and an auxiliary signal/drain. It features a pair of 22 AWG conductors with high-performance Datalene® insulation, an additional dedicated signal/ground wire, and a robust construction rated for sunlight, oil, and cable tray (PLTC) exposure.
Product Description
3106A is a hybrid cable engineered for complex automation installations where a standard shielded pair is insufficient. By including an additional 22 AWG conductor, this cable allows for dedicated signal referencing or auxiliary monitoring without the need to pull extra cables.
Key Technical Specifications
Hybrid Conductor Configuration: * Data Pair: 1 pair of 22 AWG (7x30) stranded tinned copper conductors, insulated with Datalene® for low capacitance and high-speed transmission.
Auxiliary Conductor: Includes 1 additional 22 AWG stranded tinned copper conductor with PVC insulation, useful for common-mode reference or supplemental signaling.
Dual-Layer Shielding: * Individual Foil Shield: Protects the data pair from high-frequency interference.
Overall Braid: 65% coverage tinned copper braid provides high structural integrity and immunity against low-frequency EMI.
Environmental & Safety Ratings:
PLTC (Power Limited Tray Cable): Certified for installation in cable trays, conforming to industrial standards.
Sun & Oil Resistant: Designed to maintain integrity in harsh factory environments where UV light and chemical exposure are present.
Impedance: 120 Ohms nominal, ensuring high signal fidelity for Modbus and RS-485 protocols.
Primary Applications
Advanced Modbus Networks: Ideal for installations requiring a common-mode reference wire to improve signal stability over long distances.
Industrial Monitoring: Used where remote diagnostics or auxiliary power sensing is required alongside the main data loop.
Factory Automation: A reliable choice for environments involving heavy machinery, robotics, and outdoor infrastructure where cable longevity is a primary concern.
