About Wire and Cable

Compare wire vs. cable and choose the right option based on gauge, number of conductors, insulation, and current rating.

Make your own thermocouples.

Stranded Wire—Stranded wire is more flexible than solid wire.

FEP Insulation—FEP insulation and jacket is abrasion and chemical resistant.

Fiberglass Insulation—Fiberglass insulation and jacket is rated for higher temperatures than FEP and is highly chemical resistant.

Polyimide Insulation—Polyimide insulation and jacket stands up to humid conditions and rapid temperature changes.

Silica Insulation—Silica insulation and jacket resists continuous exposure to temperatures up to 1600° F.

Ceramic Fiber Insulation—Ceramic fiber insulation and jacket withstands continuous exposure to temperatures up to 2200° F.

Thermocouple Extension Wire

Designed to carry thermocouple signals over longer distances than standard thermocouple wire, this extension wire lengthens existing thermocouple connections.

Shielded—Shielded wire has a layer of foil that blocks signal interference from nearby equipment and devices. It has an uninsulated ground wire that is not counted in the number of wires.

Stranded Wire—Stranded wire is flexible, so it’s pliable enough to be pulled around corners.

Armored Thermocouple Cords with Connectors

With plug-in connectors on both ends, these cords extend the reach of your thermocouple. Made of thermocouple materials, they prevent signal loss.

Choose a cord that matches your thermocouple type. You should also make sure the equipment you're connecting it to is compatible with the same thermocouple type.

Stainless Steel Jacket—These cords are protected by a stainless steel armor that also resists corrosion and wear.
