World renown quality of Okazaki mineral insulated cable

Okazaki’s product range, under the brand name AerOpak®, includes both MI thermocouple cable and MI RTD cable. These cables are designed to withstand a wide temperature range, from -200°C to 1260°C, which makes them ideal for hazardous and high-temperature environments. Their MI technology is also used to manufacture MI heating cable used in Aerospace and Semiconductor industry.

Key features of Okazaki’s MI cables are:

Produced exclusively with European, American and Japanese suppliers

Okazaki’s products are made exclusively with raw materials from European, American and Japanese manufacturers, which emphasize a commitment to leveraging the high-quality standards and technological advancements prevalent in these manufacturing sectors. European, American and Japanese are renowned for their stringent quality control, innovative technologies, and sustainable manufacturing practices, which aligns well with Okazaki’s commitment to quality and innovation.

Precision placement of wires

Pitch Circle Diameter (PCD) is a critical measurement in the precision placement of wires within Okazaki’s MI cables. The meticulous arrangement of wires within Okazaki’s MI cables is a standout feature. This precise placement is crucial for ensuring that the wires inside the cable are consistently positioned, without being too close to the wall of the cable, or too close to each other. PCD is playing a pivotal role in maintaining the overall quality and reliability of the cables. This level of precision is essential for automated processing of the end-user and is a testament to Okazaki’s commitment to manufacturing excellence.

Continuity in quality

Okazaki’s dedication to consistent quality is evident from their long-standing history in supplying cables to the automotive industry. From 1.5 million supplied cables, only 300 meters is reported to have been returned, highlighting the exceptional reliability of their products. This consistency is attributed to their highly optimized processes, which ensure large volumes can be produced with uniform quality, greatly benefiting from the accurate wire placement achieved through Okazaki’s process control.

Stable production

The company’s emphasis on process control is significant. They produce their own MGO pallets starting from scratch and only work with seamless tube manufacturers in Europe and Japan. Okazaki’s expertise extends to knowing precisely which starting wires and EMF calibration values are required for each type of sheath material to create Class 1 MI cables.

Calibration deviation

Okazaki’s commitment to quality is further underscored by their various certifications, including those that comply with the American Society for Testing and Materials (ASTM) and the Japanese Industrial Standards (JIS). For AerOpak® mineral insulated thermocouple is ensured that every single coil or batch is standard in line with IEC60584 class 1.  All cable is calibrated in their own laboratory, which has the highest qualifications in Japan. 

Configuration of the MI cable

Okazaki’s cables are available in a wide range of sizes and configurations, catering to diverse industrial needs. The diameters of these cables typically range from 0.50 mm up to 12.70 mm. But Okazaki can manufacture between 0.08 mm to 26.00 mm according to your purposes of use. The sheath materials include stainless steel, Inconel, and other high-performance alloys, making them suitable for extreme environments. All standard thermocouple and RTD wires are possible standard insulated with magnesium oxide (MgO). Aluminum oxide ( Al2O3 ) and silicon dioxide ( SiO2 ) are possible upon request.

Commitment to quality and accuracy

The company’s dedication to quality is evident in its numerous certificates and standards, including ISO 9001 ISO 14001 and JCSS 0079. Okazaki ensures fully traceability and products are always accompanied by material 3.1 certificates and calibration certificates. This commitment to quality and accuracy positions Okazaki as a independent market leader, continuously investing in product design and leading-edge technologies to maintain its position.
