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 often 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:
