The Amphenol
®
QWL series of electrical connectors has
been designed with the problems of multi-conductor
cable users in mind. Two of these problems, namely
water proofing and strain relief, are solved by the radial
inward compression of an internal neoprene gland in the
various cable accessories shown on the following pages.
For additional strain relief beyond that provided by the
gland, both cable grips and bar clamps are available.
Since the glands close down from .094” to .145”
(depending on shell size), the optimum condition for
cable users is to select a gland with an I.D. only slightly
larger than the maximum O.D. of the cable. The inside
diameter of the accessory housing determines the maxi-
mum diameter of the cable as shown in the tabulation
below. Smaller sizes than those shown in each shell size
can be accommodated by smaller compression glands.
Different cable manufacturers use different constructions
and cable lays in manufacturing multi-conductor cable.
The specific cabling manufacturing specification should
be known by the customer in detail in order to properly
figure each QWL application. This knowledge can save
many individual wire crossovers in any given run of cable.
Crossovers add materially to the cable diameter without a
cable accessory. In those cases where diameter buildup
is impossible to avoid, special cable accessories with
longer barrels are available.
How to order information is covered in detail on pages 4
and 5. In selecting the base number below, care should
be used, as some of the cable accessories are provided
with protection cap attachment rings, while others are
provided with the Kellems strain relief grip as shown. If a
type or cable accommodation size is not found herein
that fulfills your application, please contact Amphenol,
