Shielded Jacketed Vari Twist
Shielded Jacketed Vari-Twist® 9V283XX Series
.050″ Pitch, 28 AWG, PVC
Product Description
Belden’s shielded jacketed 9V283XX series was designed to
help meet the FCC EMI/RFI requirements. In addition, the cable
provides shielding from external electrical interference along with
excellent crosstalk attenuation. As with the 9V280XX series, the
cable supplies the electrical benefits of twisted pairs, but can be
mass-terminated in the programmed flat sections. The thin extruded
jacket allows for greater flexibility, ease of termination, reduced
space requirements, and identification of the flat sections while
providing exterior protection from the environment. The core cable
is Belden’s 9V280XX PVC series to allow easy termination to any
standard IDC connector. All cables are 100% shielded with a
Duofoil® shield (aluminum/polyester/aluminum) and can be terminated
with the two 28 AWG drain wires. Ten various conductor/pair counts
are standard; other sizes are available upon request. The cable
is UL approved (CSA available upon request) and passes the VW-1
Vertical Wire Flame Test.
Color Code: Each pair consists of a Tan conductor paired with a
color-coded conductor. Color Sequence Each Terminating Section:
Brown/Tan, Red/Tan, Orange/Tan, Yellow/Tan, Green/Tan, Blue/Tan,
Purple/Tan, Gray/Tan, White/Tan, Black/Tan. Sequence is repeated
as necessary.
Application: External interconnection or internal wiring
of electronic equipment.
