Our Durable Type J Thermocouple Cable is built to handle the demands of HVAC and automotive applications with ease. Using iron and constantan conductors for Type J thermocouples, it delivers accurate temperature readings in environments where reliability matters. We offer insulation options like FEP, PFA, or fiberglass, all rated up to 400°F (204°C), so it stands up to moisture, chemicals, and vibration. Whether you’re monitoring an HVAC system or testing an automotive engine, this cable gets the job done.
The stranded conductor design keeps it flexible, making it a breeze to install in tight spaces or complex setups. We also include aluminum foil shielding with a drain wire to block electromagnetic interference (EMI), ensuring clean signals in noisy environments. You can customize gauge sizes, insulation types, and lengths to fit your specific needs. Designed to meet IEC 60584 and ANSI MC96.1 standards, our Type J cable is a solid choice for tough applications.
