This is a ring-shaped product used to detect angle of robot joints. When combined with a dedicated magnetic sensor, it can detect absolute angle with high resolution.
As it is a magnetic product, it has superior resistance against vibrations, high temperatures, dust, oil mist. Since it is thin, lightweight, and has a hollow shape with a large diameter so that cables can be passed, it contributes to downsizing and improvement of design flexibly of robots.
In addition to the 64/63 pole pairs series, the compact and lightweight type, the 32/31 pole pairs series is also available.
