3M™ Twisted Pair Flat Cable

.050″ 28 AWG Stranded, Mass Terminatable, PVC 3782 Series

• Combines the advantages of loose twisted pairs
with flat section parts for mass termination

• Loose twisted pairs allow for easy routing

• Twisted pairs reduce crosstalk for balanced
drive applications

• Zippable for branching or discrete termination

• Wires are color-coded for easy identification

• RoHS* compliant
