Thermocouple Extension Wire | FEP Insulated – TEW&C TEX/ALTEXTWK


  • Continuous use -328F (200C) to +400F (+200C)
  • Flame Retardant
  • Excellent Dielectric Strength
  • Good Moisture, Chemical and Solvent Resistance
  • 100% Continuous Drain/Shield Contact

Overall Shield

FEP twisted overall shielded thermocouple cables are ideal for applications where the environment ambient temperatures can spike over the limit of conventional PVC cables. The twisting of the conductor and the aluminum/polyester taper shield provides protection against cross talk, static and magnetic noise in instrumentation circuits. Conductors are insulated with color-coded FEP, then twisted and shielded with tin/copper drain wire. Final layer of overall FEP jacket is applied with a nylon ripcord. The cable can be supplied in a UL listed design CL2, CL3, PLTC or ITC.
