Due to a technical problem, our website is only available to a limited extent. This also affects our download service area. We are already working on the solution and ask for your understanding.Integrated encoder solutions with magnetic sensors and magnetic ring
The magnetic sensors from Kübler detect the alternating magnetic fields of the north and south poles on a ring that is connected to the drive shaft. They can be flexibly adapted to the respective requirements in terms of resolution and magnetic ring geometry.

Flexible selection of pole length and magnetic rings
For high signal quality
If high demands are placed on signal quality, the RIM200 bearingless rotary encoders with 2 mm pole length or the RIM2000 programmable bearingless rotary encoders should be used. This requires good bearings and a stable installation process that allows an air gap of up to 1 mm.
For applications with a larger air gap
If the application requires a larger air gap (up to max. 2 mm), the RIM500 bearingless rotary encoders with 5 mm pole length are used, or the RIM5000 programmable bearingless rotary encoders. These also offer high performance and high signal quality.
Wide selection of magnetic rings
Even if a high resolution can be realized for all outer diameters, it is recommended to select the largest possible diameter.
Various mounting options
Various diameters and fastening types are available for mounting on the application shaft.
Functionality
The magnetic ring is connected to the application shaft. The sensor module records 2 signal periods, which are offset by 1/4 of the pole length, as input signals A and B. This results in 2 electrical voltages as sine and cosine signals, which are converted into square-wave signals depending on the programmed number of pulses.
An optional reference signal (1x per revolution) can be used to determine angular positions.
