AutomationDirect now offers high-quality, low-capacitance data cables designed with impedances specific for RS-232/422 and RS-485 communication applications in industrial environments. The 24 AWG tinned copper conductors are constructed as twisted pairs to reduce electrical noise sensitivity and are available in one, two, or three-pair colour-coded constructions. Polyethylene conductor insulation provides very high insulation resistance. The rugged gray PVC jacket is durable enough for use in demanding industrial applications. Protection from radiated or conducted electromagnetic interference is provided by combination shields consisting of an overall foil shield layer with drain wire and a woven braid shield layer. This shield combination offers maximum effectiveness across the frequency spectrum compared to other single layer shielded cables.
