Heating Elements

Mineral Insulated Heating Cables


Heaters and sensors for R&D, semiconductor, and high-tech systems up to 1000°C.

Within the semiconductor and chemical industry, mineral insulated heating cables are a widely used heating element. Electron provides a standard range of mineral insulated heating cables with an outside diameter from 0.5mm up to 6.5mm with a stainless steel sheath. These elements can be used up to 700°C. Special alloys such as AISI 310S or Inconel 600 can be ordered on request and can be used up to 1,000°C.


Wide range of products

Choice of different casings

  • AISI 304, AISI 304L, AISI 316L, AISI 321, AISI 316Ti
  • Special alloys such as AISI 310S, Inconel 625, Inconel 800 or others can be offered on request


Diameter range from 0.5 mm to 6.5 mm

Different designs

Depending on your request, we supply the MI heating cables in different designs:
