3M™ Round Conductor Flat Cable
.025" 30 AWG Solid, PVC
• .025 inch wire spacing increases signal density
• PVC insulation provides excellent flexibility
• 30 AWG solid conductors on .025 inch wire spacing
is designed for mass termination
• Zippable for branching or discrete termination
• Designed for use with Ultra-ATA cable assemblies
• RoHS Compliant. See the Regulatory Information
Appendix (RIA) in the “RoHS Compliance” section
of www.3Mconnectors.com for compliance
information (RIA E1 and C1 apply).
