Application Field

Tamagawa Seiki has been providing high-accurate sensor, motor, gyro and so on challenging the angle accuracy required in each period since its founding. Currently, the motion system applying such high-accurate sensor technology is expanding its activities to industrial field as well as to space industry.


From high-quality sensors and precision instruments to space equipment in perfect production environment.

Factory Application

Our products demonstrate their real value at production lines where both cost performance and quality are mandatory.


Our products (sensors for detecting the speed and inclination and active control for example) are installed on vehicles operating under electronic control such as hybrid car, Shinkansen (bullet train), escalator and elevator.

Amusement Application

We deliver reliability that functions properly even in the most rigorous environments.

Science Application

We pursue our SA business by proposing system-oriented solutions based on the integration of sensors and motors.

Construction and Civil Engineering

From sensor to system, various products are used for attitude measurement of construction machine and excavator, and adopted as measurement system of underground pipe and excavating conduit.
