Magnetic absolute encoders

The magnetic absolute encoders MAGA from Johannes Huebner Giessen are available with PROFINET IO, PROFIBUS-DP, EtherCAT and SSI interfaces. Thanks to the magnetic scanning principle these encoders are impervious to dirt and are tolerant of large radial and axial play. The version with a split pulse wheel is particularly suitable for retrofitting and upgrade projects. The patented positive fit design ensures the MAGA is suitable for high speed applications. The use of tolerance rings ensures the demands placed on the quality of the shaft are low. Individual adaptations to the encoder system to suit the customer shaft are possible.
