Incremental encoders provide a simple pulse output in relation to the movement of the sensor element across the initiator. In the case of Lenord+Bauer's magnetic measuring principle the initiator is a fero-magnetic tooth wheel.
Position is derived by the connected electronics, which can be a motion controller, PLC, counter or drive unit, by utilising a reference mark (also referred to as the Zero marker or Z channel) as the starting point. The electronics then track the pulse output from the encoder to establish position.
The Lenord+Bauer magnetic incremental encoders have internal electronics that can derive multiple "pulses" off a single tooth and in this way the encoders offer a resolution of up to 273,408 pulses per shaft revolution (GEL 260 series).
