Compact Power in Extreme Conditions

The MICROPAK HEATER® is a high-performance miniature metal-sheathed heater available in multiple compact models: MP11, MP21, MP20, MP35, MP35K, and MP36. Despite their ultra-small outer diameters—starting at just 0.8mm (0.031”)—these heaters are built to withstand harsh industrial environments while offering efficient and concentrated heat output.

Key Features of the MICROPAK HEATER MP Series

  • Ultra-small diameters from 0.8 mm to 2.3 mm

  • Capable of reaching high watt densities

  • Customizable shapes: straight, bent, or precision-wound into spirals

  • Ideal for localized heating in confined or hard-to-reach areas

  • Designed for vacuum or non-vacuum environments

  • Suitable for high-temperature sensor protection

This level of engineering is only possible through Okazaki’s proprietary manufacturing technology, which ensures the heating element is uniformly embedded in high-density magnesium oxide for optimal insulation and thermal conductivity.

Applications Across High-Tech Industries

  • Semiconductor production: Precision heating in wafer processing

  • Aerospace and aviation: Lightweight heat solutions for sensors and electronics

  • Medical equipment: Controlled heat in analytical and diagnostic devices

  • Industrial sensors: Enhancing reliability in extreme conditions
