Designed for use in extreme
conditions, Johannes Hübner
Giessen’s incremental FG/FGH 40
encoder was developed to meet the
needs of heavy industry, finding
applications in rolling mills, the
mining industry and crane systems.

The robust aluminium
housing of the FG 40 (solid
shaft) and the FGH 40 (hollow
shaft version) exhibits very high
resistance to vibration and
shock loads. Thanks to the axial
shaft seal the device not only
achieves IP65 and IP66 but also
IP67.

Furthermore, thanks to highquality
scanning electronics the FG
40 offers signal quality of the highest
standard. Track A to track B phase
displacement is 87 to 93°, the pulse
duty factor ±3%.
