Distribution and warehouse facilities frequently see a lot of activity and have many stages where errors could occur. Selecting the correct items at the picking stage is an easy way to prevent order errors. A solution is needed to guide a packer to the next item on the order and then confirm the pick.
In a book packing warehouse, the rack above each carton of books is equipped with a one-piece EZ-LIGHT PVD pick-to-light sensor. A worker fills orders by selecting the quantity of each book specified on the packing slip. To make it easier for the worker to find the cartons from which to pick books, the PVDs above those cartons are illuminated. The PVD detects the workers hand in the carton to verify that the title was picked.
