With the light-based material supply system, instead of a picking list, the operator is informed of the items and quantities to be picked via a compartment display located directly on the picking compartment.
The synonymous terms pick-to-light or pick-2-light (P2L) are often used for the term pick-by-light. The term put-to-light refers to the reverse process.
A Pick-2-Light compartment display consists of at least one eye-catching light that can be seen from a distance. Pick-by-light systems achieve their maximum efficiency with short walking distances and high pick frequency per storage location.
In the opposite case, for example a spare parts warehouse with long walking distances and low pick frequency per storage location, mobile picking systems offer a suitable solution option. For this purpose, standardized or customized vehicles are equipped with a power supply, WLAN connection, operator guidance and compartment displays.
