Belden 9842 060, Multi Conductor Cable 2 Pair 24 AWG PVC

Belden 9842 is a 2-pair, 24 AWG low-capacitance data cable engineered for reliable RS-485 serial communication in electrically noisy industrial environments. Built with stranded tinned copper conductors, polyethylene insulation, and dual-layer shielding—100% Beldfoil® foil plus 90% tinned copper braid—this cable delivers dependable signal integrity for long-distance runs connecting PLCs, VFDs, HMIs, RTUs, and SCADA systems. Its 120-ohm characteristic impedance matches the RS-485 specification, and its CM fire rating makes it suitable for general-purpose indoor installation. Sold by the foot with no minimum order at Ramcorp Cable.
