Round 'n' Flat cable combines the handling and shielding features of round cable and the mass termination
capabilities 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 termination. 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 referencing. Two layers of shielding, aluminum-
polyester foil and tinned copper braid are used to protect signals from EMI interference.
