About Wire and Cable

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

Thermocouple Wire

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.

Armored Thermocouple Cords with Connectors


Male × Female Flat-Pin Mini Connector	Male × Female Round-Pin Connector

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.
