The overspeed function operates by way of a centrifugal switch and requires no external power supply. The overspeed can be calibrated standard between 800 and 4,000 rotations per minute. Impact, vibrations, (limited) axial and radial load are no problem for these encoders. Our product range includes single, double or even triple encoder assembly. In addition, a choice can be made from redundant versions by means of additional electronics, integrated in a single encoder, or two or three encoders placed in line.
