Applications of Kübler encoders

Various applications of industrial automation

Encoders are used wherever lengths, positions, rotational speeds, and angles need to be recorded. They convert mechanical motion into electrical signals. There are differences in the functional principles of encoders. They can thus be divided into incremental and absolute versions.We can generally supply you with all of the encoders in both shaft and hollow shaft models.

The use of hollow shaft encoders reduces costs by up to 30% and installation space by 50% compared to shaft models. This is made possible by the fact that additional couplings, mounting devices and other fixing aids are not required. To install a hollow shaft encoder, it is simply pushed onto the drive shaft, clamped and, in the simplest case, secured against rotation using a cylindrical pin. In addition, hollow shaft encoders generally require a smaller installation depth.

Application examples for encoders


Angle measurement

Encoders can measure angles by the number of pulses per revolution. This is mainly used in industrial automation, whereby Kübler encoders are used in many different applications.

Length measurement

Encoders provide the most accurate information when measuring lengths and distances. This is possible via the number of pulses per revolution that are counted. Rotational speeds can also be recorded with the aid of encoders.

Position detection

In mechanical systems or hydraulic gripper arms, encoders detect the exact position in both vertical and horizontal planes.

Speed measurement

Encoders measure the speed of motors in drive technology, for example. Acceleration can also be measured using encoders.

Kübler encoders are used in these industries

Functional principles of encoders


Optical scanning (incremental)

A rotatable disc is mounted between an LED and a receiver unit. A grating is applied to this disc. The light emitted by the LED is modulated by the screen and the grating and strikes the receiving unit, which delivers a signal proportionate to the brightness. When the disc is rotated, this signal has an approximately sinusoidal shape.


To the incremental encoders

Optical scanning (absolute)

The light emitted by an LED is modulated by a code pattern applied to a rotating disc and scanned by a special Kübler Opto ASIC. Each position is assigned a unique bit pattern, which is usually available as a Gray Code. The advantage over incremental encoders is that, when the encoder is switched on, any motion of the shaft in a de-energized state is immediately detected and the correct position is available.


To the absolute rotary encoders

Magnetic scanning

The magnetic field generated by a rotating permanent magnet is scanned by an ASIC sensor. Each angular position is based on field vectors, which are converted into an electrical signal by the ASIC. Depending on the model, this is transmitted as an incremental signal, in absolute form as SSI, 0 to 10 V, 4 to 20 mA or as a Fieldbus signal.
