3M™ Round, Shielded/Jacketed, Flat Cable
.050" 28 AWG Stranded, Mass Terminatable, PVC/PVC 3659 Series
• Round construction permits easier routing
• 28 AWG wire on .050 inch pitch permits mass
     termination to broad line of IDC connectors
• Continuous split/bond repeat allows for mass
     termination on 2.4 inch centers (approximate)
• Primary cable is zippable for branching or discrete terminations
• Meets external wiring requirements of National
     Electrical Code, Article 725 (CL2)
• UL listed for USA and Canadian markets
• Dual shielding provides 35 db average shielding
     effectiveness
• See Regulatory Information Appendix (RIA) for
     chemical compliance information
     (RIA E1 & C1 apply)
