The new magnetic rotary MAG (-G) 50 ... 1200 of Johannes Hübner can be installed without bearings without bearing. The system is resistant to shock and vibration and delivers trouble-free signals even under extreme conditions. It complements the common optical sensing principle, which must be protected in a closed housing with a mounted shaft.
With the magnetic scanning principle, a fixed sensor detects the magnetic field changes of a rotating magnet wheel with north-south poles. The changing magnetic field generates a sinusoidal or rectangular voltage in this sensor. Further advantages of the magnetic scanning principle: It is insensitive to dirt and enables large radial and axial tolerances. The magnetic encoders work wear-free and silently. The variant with a divided magnet wheel is particularly suitable for retrofitting and modernization as well as applications without a free shaft extension.
Magnetic encoder technology takes place e.g. B. Use in steelworks, ship drives, gas and water turbines, pumped storage power plants, large open-cast excavators, conveyor systems and drilling rigs. It is characterized by its very narrow design and can therefore be used on site even in very confined spaces. The system can be flexibly adapted to the respective installation situation of the customer application with shaft diameters from 16 to 1000 mm. Depending on the structural conditions, you can choose from various pole wheel mounting options such as screw mounting, heat shrink mounting, clamping element mounting, mounting washer mounting or tolerance sleeve mounting. Sine signals, incremental signals and absolute value signals (SSI, Ethercat, other bus interfaces) are available as electrical output signals for the magnetic encoder systems.
