Description: .050" centerline, 28 AWG Twist 'N' Flat, Fully Laminated, PVC insulated
Family: Internal Twisted Pair

Outline Drawing

Spectra-Strip Twist 'N' Flat� cable combines the time and cost savings of mass termination with the electrical performance of twisted pairs, making it ideal for high speed computers and communications equipment. Labor savings of up to 95% as compared to automatic strip and crimp termination are readily achieved.

Twist 'N' Flat� cable consists of stranded round conductors insulated with color coded PVC, twisted into pairs and laminated between layers of PVC film to form a planar cable. The twist in adjacent pairs is reversed to reduce cable crosstalk even further. Standard cables alternate 18-inch (45,7cm) long twisted pair sections with 2 inch (5,1cm) flat sections in which the conductors are laminated in parallel.

Twist 'N' Flat� cable can also be fabricated to your custom requirements. Flat sections can be made longer to allow room for multiple connectors. Twisted pair length can be varied from a minimum of 6 inches to many feet to conform to your requirements. The lamination can be fabricated "loose" at specified points to provide easy access to individual conductors. For complete details, consult the Spectra-Strip sales office nearest you.

  • UL / CSA certified
  • Twisted pairs for significant crosstalk reduction
  • Up to 64 conductors (32 pairs) with precise spacing for controlled electrical characteristics
  • Double sided lamination provides excellent conductor strain relief and mass termination from either side of cable
  • Reduced assembly costs compared with discrete or hand lamination terminations
