QWL Series - Amphenol Aerospace

QWL – accessoriescabling informationThe Amphenol ® QWL series of electrical connectors hasbeen designed with the problems of multi-conductorcable users in mind. Two of these problems, namelywater proofing and strain relief, are solved by the radialinward compression of an internal neoprene gland in thevarious cable accessories shown on the following pages.For additional strain relief beyond that provided by thegland, both cable grips and bar clamps are available.Since the glands close down from .094” to .145”(depending on shell size), the optimum condition forcable users is to select a gland with an I.D. only slightlylarger than the maximum O.D. of the cable. The insidediameter of the accessory housing determines the maximumdiameter of the cable as shown in the tabulationbelow. Smaller sizes than those shown in each shell sizecan be accommodated by smaller compression glands.Different cable manufacturers use different constructionsand cable lays in manufacturing multi-conductor cable.The specific cabling manufacturing specification shouldbe known by the customer in detail in order to properlyfigure each QWL application. This knowledge can savemany individual wire crossovers in any given run of cable.Crossovers add materially to the cable diameter without acable accessory. In those cases where diameter buildupis impossible to avoid, special cable accessories withlonger barrels are available.How to order information is covered in detail on pages 4and 5. In selecting the base number below, care shouldbe used, as some of the cable accessories are providedwith protection cap attachment rings, while others areprovided with the Kellems strain relief grip as shown.
