Datalogic optical encoders are used for conveyor belt motion control and linear measurement. Incremental encoders produce sinusoidal or square wave outputs, which give an incremental number of pulses per revolution of the shaft. The resolution is defined as Pulse Per Revolution (PPR).Absolute encoders generate a multi-bit digital data information, providing the actual angular position of the shaft. Single-turn absolute encoders repeat the code for every shaft revolution. Multi-turn absolute encoders increase the code at each shaft revolution. Shaft position is retained when the absolute encoder is switched-off, so it can provide the absolute position, as well as rotation speed or direction. Datasensor incremental encoders give a number of pulses per revolution, wheres absolute singleturn or multiturn encoders give a different digital code for each position.
Datalogic provides the widest range of photoelectric sensors for universal and applications specific purposes, such as colour, contrast and luminescence sensors, fork sensors for label detection, as well as devices for dimensional and distance measurement.
Datalogic inductive and capacitive proximity offers a reliable detection where photoelectric is not applicable. Datasensor inductive sensors are used for metal parts at close distance, wheras Datasensor capacitive sensors are suggested for any material inside opaque containers. Datalogic inductive proximity sensors generate a magnetic field from their detection faces. Whenever a detectable object moves into the sensor’s field of detection, Eddy currents build up in the target and dampen the sensor’s magnetic field. This effect triggers the sensor’s output. Since a current in the target is needed for detection, inductive proximity sensors are uniquely suited for detection of all types of metals.
Datalogic ultrasonic sensors offer a reliable distance measurement, based on ultrasounds transmission and reflection, for an accurate positioning control, without influence from object colour or light reflection, also in presence of clear transparent objects, whereas Datasensor ultrasonic fork sensors are used for clear label detection.
