They record the speed and direction of rotation directly on the motor or gearbox. With a measuring range from 0 Hz to 20 kHz, they detect even the smallest movements of the drive. The robust and at the same time high-resolution sensors were developed for use under the harshest environmental conditions.

They are suitable e.g. for traction control and train protection. The maintenance-free, wear-free, magnetic measuring system in a thick-walled stainless steel housing withstands shock and vibrations. Certification according to DNV GL, SIL, ATEX or IECEx is optional.
