3659_1 Datasheet, PDF (1/5 Pages) 3M Electronics – 3M Round, Shielded/Jacketed, Flat Cable .050 28 AWG Stranded, Mass Terminatable, PVC/PVC

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)
