Introduction
Round ’n’ Flat cable combines the handling and shielding features of round cable and the mass termination capabi-
lities of flat cable into a single construction. This product is designed for routing in tight spaces where a round shape
is more practical and where a foil braid shield is necessary to help meet FCC requirements for EMI/RFI suppression.
The inner cable is extruded Spectra-Zip with alternating sections that are flat and slit. Each flat section is 3/4” in
length with conductors on controlled spacing of .050” + .003” making it ideally suited for IDC mass termination
methods. The alternating flat and slit sections also offer an advantage over standard round cable for hand termina-
tion. The flat sections keep the conductors aligned for conductor positioning while the slit zip feature provides easy
breakout of individual conductors
One edge of the flat cable is marked for conductor re-
ferencing. Two layers of shielding, aluminum- polyester
foil and tinned copper braid are used to protect signals
from EMI interference.
