Which equipment uses sensors to measure items and route them to the correct location?

• A. Conveyor
• B. Sorter
• C. Palletizer
• D. Robot arm

Answer: (B)

Routing items to the correct location based on measurements from sensors is what a sorter does. In automated sortation, sensors capture item attributes such as size, weight, barcodes or RFID, and sometimes color or destination codes, and a control system decides which output path each item should follow. Diverter mechanisms then steer the item onto the appropriate conveyor lane or chute, completing the routing. This makes sorting equipment the best fit for the description, because its primary function is to identify items and direct them to the right location. A conveyor mainly moves items along a line without deciding their destination; a palletizer stacks items, and a robot arm focuses on picking and placing, whereas the sorter integrates sensing with automated routing.
