Ultra-thin 0.08mm J Type Thermocouple Wire with PFA Insulation and Iron-Constantan Conductors

J Type Thermocouple Grade Wire is designed for temperature sensing and thermocouple manufacturing applications. It consists of two different conductors: Iron (Fe) as the positive leg and Constantan (Cu-Ni) as the negative leg.

This type of thermocouple wire provides stable thermoelectric performance and reliable temperature measurement in industrial environments. It is commonly used for manufacturing J type thermocouples, temperature sensors, heating equipment, industrial ovens, machinery, molds, and process temperature monitoring systems.

Typical J Type thermocouple temperature range: -210°C to +760°C

The actual operating temperature depends on the wire diameter, insulation material, and application environment.

• Ultra-small conductor diameter (0.08 mm) - Low thermal mass brings ultra-fast thermal response, which can capture rapid temperature changes. Small overall dimension allows wiring inside narrow, compact spaces where ordinary cables cannot fit. Good flexibility permits repeated bending in confined assemblies.
• PFA insulation & sheath properties - PFA fluoropolymer features wide operating temperature range from -75°C to 260°C. It delivers excellent chemical resistance against acid, alkali, solvent and oil, outstanding dielectric strength, moisture-proof and flame-retardant performance, and stable electrical performance in harsh environments.
• Measurement reliability - Fine-gauge J-type wire maintains good thermoelectric accuracy, suitable for short-cycle dynamic temperature monitoring. The integrated PFA sheath prevents short-circuit and conductor oxidation, extending service life.

• Rapid-response temperature testing in laboratories and R&D
• Micro-component temperature monitoring for electronic devices, MEMS and miniature sensors
• Thermal analysis, material curing, plastic processing and heat-treatment equipment
• Aerospace, automotive component thermal test, vacuum and corrosive-environment temperature measurement
• Precision equipment internal wiring with strict space constraints
