3M 3659 User Manual
.050″ Round, Shielded/Jacketed, Flat Cable
28 AWG Stranded, Mass-Term, 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
