conpany photo We strive to become more environment-friendly, to become an enterprise worthy of ever-greater trust by our customers.
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 the few makers 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.
