Actions such as conveying, lifting, pick-and-place, and other automated functions represent one or more axes of rotary motion found in material handling equipment. For accurate control, often a rotary encoder is a preferred sensor for motion feedback.
Many material handling functions are driven by servo or vector duty motors. These usually have integral encoders for closed-loop motion control feedback. Alternatively, the encoders can be applied to a non-motor axis. Both incremental and absolute encoders are widely used in material-handling equipment.
The Material Handling industry typically uses encoders for the following functions:
