  • Thermocouple Cable - EX, JX, KX, TX 600V, 90 °C Wet or Dry

    For use as a 600 Volt, multi-pair thermocouple instrumentation cable where flame-retardancy, and moisture/chemical resistance is critical. Cable can be installed in free air, in raceways, or direct burial. The cable is also approved for wet or dry locations as well as Class 1 Division II industrial hazardous locations per NEC 501-4(b) for (UL) Type Tray Cables (TC).
    Temperature rating of 90 ºC wet or dry. Insulation provides excellent electrical, thermal, and physical properties, excellent flame resistance and resistant to crush, compression, cuts and heat deformation. Also conductor insulation provides good low temperature (-40 ºC) cold bend characteristics.
    Approved for direct burial.


    • Conductor is thermocouple alloy per ANSI MC96.1 - 1982.
    • Extruded flame-retardant ethylene propylene rubber (EPR) insulation.
    • Conductors twisted together with a drain wire and aluminum mylar shield. Shielded pairs cabled together with fillers as needed to form a round core. An overall aluminum Mylar shield and drain wire is applied over the core.
    • Pairs are color coded per thermocouple type with pair number printed on the negative (red) conductor. See chart below for specific color codes.
    • Black, flame-retardant, sunlight resistant, Chlorinated Polyethylene (CPE) jacket. Available with color coded jacket.
    • Available with class B stranding per ASTM B174.
    • Insulated Conductor - VW-1.
    • UL Type TC, 90ºC Wet or Dry, 600V
