TAMAGAWA SEIKI
Continuing to Challenge “Angle” and “Accuracy”
History
The history of TAMAGAWA SEIKI CO., LTD. can be traced back to March 1938, when the company‘s founder established the company near the Tamagawa River in the south of Tokyo. In 1942, he set up the Iida plant in his hometown, Iida city of Nagano prefecture, to contribute to regional industrialization.
After World War II, we immediately started to develop, produce and sale instrument motors anticipating diverse needs of the age. The business was expanded to automatic control equipment and aerospace instruments with the motto “grow technology and sale technology”. The technology is symbolized by our registered trademarks, “MOTORTRONICS”, “SPACETRONICS”, “Smartcoder” etc.
We are determined to continually train the strength of product development and sales forces, to flexibly meet customer’s requests by our product quality and performance and to grow up as a “Glocal (Global + Local ) Company” which can supply the only /number one products.
Business
Since its foundation, Tamagawa Seiki has taken up the challenge of angular precision for control equipment, such as high-precision sensors, motors and gyros, and successfully delivered such equipment to its customers.
We are now one of few manufacturers in the world with the capability to develop and manufacture both two-dimensional and three-dimensional (spatial) position/angle sensors.
We have applied leading-edge high-precision sensor technology to our “Motion System”, whose fields of application are extending even to the space industry.
