Plug-in couplings

The isolated and corrosion proof CPS couplings compensate an increased parallel misalignment up to ±2 mm and an increased axial misalignment up to ±1.5 mm as well as extending the service life of encoders in the process. The CPS couplings are optionally available with attachment options without lateral access for large bore diameters up to 40 mm as well as for shafts without a feather key (clamping).
