Kelsey Acoustics has launched Duracat, a tough Cat5 DMX and AES data cable for industrial applications which provides a durable and reliable data solution for patching, theatre, studio stage and public area usage. According to Kelsey's Michael Whiteside, the brief for this cable was to produce a tough, "stage-proof" Cat5e cable that terminates with standard RJ45 connectors and yet has a build that provides real protection for its structure as a data cable. "We have gone to great lengths to ensure that Duracat is constructed for maximum flexibility combined with the strength and durability that is fundamental to the accurate transmission of data," he commented.

Satisfied customers already include Marquee Audio who have used Duracat for a recent theatre installation, and rental company SSE who were delighted with every aspect of the cable's performance in a live environment and have subsequently ordered a significant quantity. Internally, Duracat is built as a Cat5e patch lead, using stranded copper conductors that give it strength with flexibility. The pairs are orbitally spun round each other rather than twisted which prevents strain and means they stay in a 'natural' position. This also enhances its electrical consistency. A plastic foil followed by a loose wrap screen around the four pairs maintains a low capacitance and gives the components protection against internal abrasion.

The inner sheath fits exactly onto RJ45 connectors, for correct and secure crimp termination, whilst the outer sheath provides a durable wall to protect the internal structure from distortion. The outer jacket, which is stiffened to maintain consistent impedance yet still remain flexible, fits snugly into Neutrik-type cable glands, making it ideally suited to Kelsey’s Duracon, Neutrik Ethercon and DMX 3- and 5-pin connectors. Finally, the all low smoke and halogen-free construction meets the new fire regulations for many public and work areas while the overall shield provides immunity from interference and compliance with EMC directives.
