The flexible encoders

The bearingless, magnetic incremental MAG encoder systems are particularly flexible; thanks to the version with pulse wheel and scanning head they offer the highest levels of design freedom. They are suitable for direct attachment to shaft diameters up to approx. 1500 mm. Thanks to their narrow width of just 15 mm they are also particularly suitable for use in confined spaces. The pulse wheel is mounted directly onto the shaft where it also measures high speeds without any difficulty. MAG encoder systems are suitable for harsh operating conditions such as in roll stands, drive shaft assemblies on ships, for motors on excavators in open cast mining, tandem motors as well as gas and water turbines. The module variant with split pulse wheel offers a practical alternative for retrofitting and upgrading purposes or if there is no free shaft end available.
