Contrary to inductive proximity switches, pulse sensors are, by their high geometrical resolving power, suitable for the detection of fine textures and fast motions (not suitable for axial approach and non-magnetic materials). Pulse Sensors are mainly used for the determination of rotational speed and rotating direction of waves with the help of gear wheels starting from module 0.3. This allows to use these sensors in particular for speed monitoring, incremental encoding, for counting tasks, for position controlling, and forward-backward recognition. These sensors are, for example, also suitable for sensing racks or magnetic tapes in order to detect the speed and direction of linear motions.
For more information on Relays for pulse rate, rotational speed and frequency go to chapter Measuring Relays and Controllers / Rotational Speed and Frequency.
