Incremental magnetic encoder

No matter if destined for drive shafts on ships, for engines powering open-cast mining excavators, for tandem motors or gas and water turbines – incremental magnetic encoders from Johannes Huebner Giessen are a reliable, safe and flexible solution for even the harshest of environments. Utilizing a magnetic, non contact scanning principle the encoders are tolerant of large axial and radial play. Large shaft diameters up to 1500 mm possible. The noiseless magnetic encoders do not generate any heat. The version with a with split pulse wheel is particularly suitable for retrofitting and upgrade projects.
