Measuring wheel encoders
- Finely-adjustable contract pressure enables high process quality and process reliability on various surfaces
- Each linear measuring task can be optimally solved due to different measuring wheel surfaces and adjustable contact pressure
- Customized combinations possible thanks to a wide selection of encoders, interfaces and measuring wheels
- Smart design for easy integration into the application and control environment
- Time-saving thanks to easy integration and quick commissioning
- Contact pressure and maintenance position can be adjusted without tools
The MWS120 is a measurement systems which detects linear movements directly and reliably. With a spring travel of 10 mm and the contract pressure with easy manual adjustment, movements of the measurement surface can be compensated for vertical to the measurement direction. This enables precise measurement while ensuring gentle contact with the measurement surface. Changing to the maintenance position is also done easily and securely by hand. This makes it possible to do maintenance work is a short amount of time. Thanks to the smart design and an axle spacing of only 120 mm, the MWS120 can be integrated optimally into the application. A large selection of different encoders and interfaces as well as measuring wheels with different surfaces and diameters offers individual solutions.
- Contact pressure can be adjusted manually from 0-24 N in 6 steps
- Compact axle spacing (120 mm) for flexible installation options
- Maintenance position can be reached manually
- Selection of various measuring wheel surfaces and diameters
- Incremental or absolute encoder interfaces can be combined
Innovative, convenient handling, reliable operation
Easy, convenient and reliable: The MWS120 is quick to integrate and can be put into operation manually without tools thanks to the intelligent design. This makes operating the measuring wheel system particularly easy.
Smart design for quick mounting and reliable integration
The MWS120 is designed for the highest level of usability. That means that the measuring wheel system is installed with only four short mounting steps and is ready for operation right away.
Thanks to the clever design of the MWS120, the spring tensioning force can be flexibly adjusted by hand from 0 N to 24 N – in 6 increments of 4 N each, and without using any tools. This means the measuring wheel system can be optimally adjusted to the measuring surface. In addition to protection from damage, the MWS120 guarantees constant contact to the measurement surface. The device has the right measuring wheel surfaces for any material the MWS120 measures. This also improves the reliability and process quality of linear measurements.
The clever device design enables the combination of different measuring wheel surfaces, scopes and encoders. This makes possible quick mechanical and electrical integration of the MWS120 into the respective application and control environment. Encoder and measuring wheel can be mounted flexibly on both sides of the spring arm. The measuring wheel system can be installed clockwise or counterclockwise, from above or below in reference to the measurement surface – the MWS120 delivers reliably precise values in any position.
Mounting and handling in no time: The MWS120 can be integrated into systems without great effort. Adjustments to the spring tensioning force are done in seconds.
One measuring wheel system, many communication interfaces
The MWS120 can easily be integrated into existing control environments. All common industrial interfaces such as IO-Link, CANopen, SSI, incremental interface, EtherNet/IPTM, EtherCAT® and PROFINET are available for the measuring wheel system. Whether for Smart Tasks via IO-Link, mobile parameterization via CANopen interface or extensive diagnostic functions via EtherCAT® or PROFINET, the MWS120 takes advantage of all the possibilities offered by the respective industrial environment and can therefore be very easily integrated into Industry 4.0 processes. Computer-supported programming of the MWS120 using the SOPAS configuration software is also possible.
At home in nearly any surroundings: Thanks to the freely-selectable interface, the MWS120 can be integrated into nearly any control environment, thereby providing all possibilities for individualized on-site process optimization.
From measuring wheels to non-contact sensors – SICK has a wide range of devices for linear measurement of endless material or piece goods.
Whether endless materials or piece goods, paper, plastic, metal, wood or textiles: Exact position and speed data is essential for industrial automation. You decide on the quality and productivity of fully-automated processes. That is why SICK offers a wide range of solutions for linear measurements, from measuring wheel encoders with incremental or absolute interface to encoders, motor feedback systems, pulley systems and the SPEETEC 1D non-contact motion sensor. The latter provides high-precision data on piece goods and endless material. This is what creates the optimal combination of performance and economic efficiency for any application.
Optical or tactile measurement, endless material or piece goods, incremental interface or IO-Link: SICK offers the right solution for any challenge in linear position and movement measurement and helps make industrial processes even more efficient.

- 1) The surface of a measuring wheel is subject to wear. This depends on contact pressure, acceleration behavior in the application, traversing speed, measurement surface, mechanical alignment of the measuring wheel, temperature, and ambient conditions. We recommend you regularly check the condition of the measuring wheel and replace as required.
