Ninomiya K Super Ultrathin – Fluorocarbon Insulated Thermocouple Wires

Features

  • Using fluorocarbon-resin as insulation material to make it very thin (OD is 1/2 of normal products), very flexible and small in finished outer diameter.
  • Excellent thermo responsivity due to low thermal capacity.
  • Excellent machining properties, because the strength is not weakened so much after machining by making the outer sheath thinner instead of reducing diameter of the conductor.
  • Using fluorocarbon-resin as coating material, highly resistant to heat(-200 to +260℃) and chemical.

Ninomiya K Super Ultrathin – Fluorocarbon Insulated Thermocouple Wires

Our ultra-thin fluorocarbon duplex insulated thermocouple wire features K-type thermocouple elemental wires (Chromel/Alumel) conforming to JIS C 1602 standards. These wires are coated with fluorocarbon-resin (PFA) for insulation.

In addition to the above specifications, we are equipped to manufacture products categorized under class 1, section 1, and other types of duplex-insulated thermocouples upon request. Please feel free to contact us with any specific requirements.

Please note: Fluorocarbon-resin emits toxic gases harmful to humans when burned. Therefore, avoid burning the product during processing or use.

Comparison with other products

  • Front: K-super ultrathin / Back: 0.1x1P K-PFA
  • Both utilize 0.1 mm conductors for K-type thermocouples, but K-super ultrathin has a finished outer diameter that is half the thickness of 0.1x1P K-PFA
