This termination features swaged magnesium oxide insulation surrounding the elements, with silicone-impregnated fiberglass leadwire insulation swaged approximately 3\/4″ into the sheath.","* The fiberglass insulation protects the integral leadwires under mildly adverse atmospheric conditions (not recommended where excessive vibration and abrasion are encountered). * Standard cold end lead length is 24″. Longer leads are available on request. Specify in feet, e.g. T2(3FT). * Available with the following sheath sizes: 0.062″ (AWG 30 leadwire), 0.125″ (AWG 24 leadwire), and 0.187″ (AWG 20 leadwire). Maximum sheath length is 5 ft. * Service temperature upper limit: 700°F (370°C)
