Data communication cables
Data communication cables
Improved sensors, instruments, sophisticated control and automation systems are being relied upon to achieve the optimum levels of plant efficiency. Critical to the performance of these new tools of productivity are wires and cables, which reliably transmit signals and data under harsh environmental conditions. The RS 232/422/423/485, data bus cables are manufactured in a wide range of sizes, insulation materials, shield configurations, jacket materials, armoured/unarmoured to meet the specific applications. All data communication cables are normally shielded cables in multicore or multipair configuration. The cables are normally provided with an overall shielding by aluminium-polyester tape or a tinned copper braid shield. In applications where the protection of signal integrity is critical a combination of foil and braid shield is provided for maximum shield effectiveness. Moreover cables can also be provided with individual core or pair screening where necessary. The cables are available in various conductor sizes ranging from 26 AWG to 22 AWG, i.e., 0.14 to 0.34 sq.mm. The cables are specially designed for low capacitance and specific impedances. Twisted pair cables offer reduced noise interference and hence data speeds are usually higher than those of multicore cables. The cores are normally colour coded for easy identification. Custom designed, import substitute cables are also available.
