BELDEN 9843 3 PAIR MODBUS DMX
Belden 9843 is a high-density, three-pair shielded twisted pair cable designed for complex RS-485, Modbus, and industrial control applications. It provides the same reliable signal integrity, low-capacitance performance, and dual-layer shielding as the 9841 and 9842, but offers expanded connectivity with three distinct conductor pairs.
Product Description
Belden 9843 is engineered for environments where multiple serial communication lines must be routed together. By consolidating three pairs into a single, shielded cable assembly, it reduces installation time, space requirements, and labor costs in multi-drop network configurations.
Key Technical Specifications
Conductor Construction: Three pairs of 24 AWG (7x32) stranded tinned copper conductors. The stranded wire provides essential flexibility for routing within control panels or cable trays.
Dielectric/Insulation: High-quality Polyethylene (PE) insulation minimizes signal loss and maintains strict 120-Ohm characteristic impedance.
Dual-Shielding Architecture:
Beldfoil® Shield: 100% coverage aluminum/polyester foil to eliminate high-frequency RFI.
Tinned Copper Braid: 90% coverage tinned copper braid to provide superior low-frequency EMI protection and mechanical grounding support.
Outer Jacket: Flame-retardant PVC (rated CM), providing a rugged exterior to protect the conductor pairs from physical abrasion and moisture.
Primary Applications
Complex Control Networks: Ideal for large-scale Modbus installations requiring multiple master/slave channels.
Industrial Automation: Used for interconnecting PLCs and remote I/O blocks where multiple signals must be transmitted in a single conduit.
Lighting and Stage Control: Useful in larger DMX or architectural lighting systems where multiple universes or control lines must follow the same pathway.
