Thermocouple Type K Wire

At Aerospace Wire & Cable we offer Type K in both thermocouple wire grade, and extension grade in both solid and stranded constructions. Temperature ratings for insulating materials range from 60ºC to 260ºC. Cables with SLE conductors are also available upon request.

Customization capabilities regarding color codes, cabling, shields, AWG sizes are available upon request.

Thermocouple type K is an electrical cable that is comprised of chromel (positive) and alumel (negative). It is the most common thermocouple type because it provides the widest operating temperature range (-270ºC - 1,260ºC*). Because Type K thermocouples are nickel-based and possess great resistance to corrosion, these thermocouples have the widest operating temperature range, and work in most applications.
