Part Information: Part Number: 159-2801-020 Description: Round and flat, aluminum and braid shield, .050 pitch, 28 awg, 20 conductors Family: Round and Flat Outline Drawing Introduction 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. Benefits Round cable that mass terminates High flexibility Helps meet FCC requirements UL, CL2 CSA Certified Specifications Physical Conductors 28 AWG, 7/36 Tinned Copper Color code Gray with Red Edge Insulation PVC, .010 WALL Thickness: .035 .003 Pitch .050 .00 Aluminum/Polyester Foil, with Minimum 85% Shielding Coverage Tinned Copper Braid Jacket Black PVC, .030 nom Wall Liner Paper Liner Between Jacket and Braid Temperature -20C to +105C (-4F to 221F) Rating UL style Inner Cable: 2651 UL Listed Power Limited Circuit Cable CL2 Composite CSA AWM I/II A 105uC 300V, FT-1 Electrical Voltage 300 volts *Impedance 75 ohms *Capacitance 24 pf/ft at 1 MHz (78.7 pf/m) *Inductance 15 H/ft at 1 MHz (.49 H/m) Propagation Delay 1.60 ns/ft (5.25 ns/m) *Above values measure in the ground-signal-ground mode with the shield also grounded. *Above values measure in the ground-signal-ground mode with the shield also grounded.
