Belden 3109A 010, Multi Conductor RS 485 4 Pair 22 AWG SH PVC
Description
Belden 3109A 010 is an RS-485 multi-pair cable designed for data communication in harsh environments. It features 4 twisted pairs of 22 AWG (7x30) TC - Tinned Copper conductors with PE - Polyethylene (Foam) insulation. The cable uses an Overall Beldfoil® (100% coverage) and Tinned Copper braid (65%) shield, plus a 22 AWG (7x30) TC drainwire. A black PVC - Polyvinyl Chloride outer jacket supports Environmental suitability: Indoor, Outdoor, Sunlight Resistance, Oil Resistance, with CM and PLTC ratings and a UL Voltage Rating of 300 V (CM, PLTC).
