Available Configurations

Properties common to all products in this list

Composition: Cu 55/Ni 45 Form: Insulated Wire Material: Copper/Nickel (Constantan®) Commodity: Alloys Insulation: Polyurethane
Polyurethane Constantan® Thermocouple Insulated Wire is designed for precise temperature measurement in high-performance thermocouples. Its polyurethane insulation provides excellent abrasion resistance, flexibility, and durability, making it ideal for robotics, HVAC systems, and lab instrumentation. This thermocouple wire is commonly used in engineering applications such as process monitoring, automation, and industrial sensors, where reliable short-to-medium-term temperature measurement is critical. Additionally, its resistance to abrasion, oils, and select industrial chemicals ensures long-term performance in dynamic and mechanically demanding environments.
