Fused Kapton® tape applied to conductors and jackets. Excellent moisture and abrasion resistance, high dielectric strength (7 kV/mil) retains much physical integrity after gamma radiation. FEP is used as adhesive binding agent (melts at approx. 500°F). In many stationary applications the wire can potentially withstand 600°F for prolonged time periods due to bi-directional overlapping insulation design.

What is the minimum rated temperature for this product? The datasheet linked on this page does not include it, and the product page lists 0C, but the datasheet for "Fine Gauge Thermocouple Wire" rates KK type insulation down to -267C. Which is it?

Asked by: SD123
The probes with Kapton insulation are rated for use down to -200C but below 0C they would be expected to meet the Standard Limits of Error accuracy specification unless calibrated.

I am looking for the cross sectional dimension of this wire. KK-J-24S-SLE-100 Thank you.

Asked by: JPaez
The cross sectional dimensions of KK-J-24S-SLE-100 wire are 1.3mm x 2.2mm or 0.050" x 0.085". The wire has more of a rectangular appearance much like a lamp cord.

We bought thermocouple K type (KK-K-24-100) which didn't have color code on it. How can I figure out which wire is negative or positive?

Asked by: Anonymous
Thank you for connecting with Omega Engineering. Type K thermocouple wire will have one red negative lead and one positive yellow lead.

Has KK-K-30-1000 been tested in vacuum environments? How much does it outgas?

Asked by: vacuumwire
Thank you for the inquiry. KK-K-30-1000 has not been tested in vacuum. The construction is kapton tape bonded with a PFA adhesive so there would be some outgassing due to the adhesive. Best regards OMEGA
