Incremental or Absolute Rotary Measurement

Siko's Magnetic Rings are magnetically encoded plastic bands which are supplied unmounted or bonded to a solid ring or flange. To prevent measurement inaccuracy at the tape joint, the bonding is done first, and then followed by the magnetic encoding. Due to Siko's high quality manufacturing process, 360o measurement is possible. A key benefit of this technology is that the measurement is done without any contact between the magnetic ring and magnetic sensor, meaning there are no wearing parts, whilst also being insensitive to dust, water and non-ferrous debris.
