Pick to Light

Pick by Light and Put to Light

Pick by Light is a picking system with signal lamps on storage locations

Pick by Light is a semi-automated, paperless picking system. With the use of Pick by Light, conveyor systems, and our proven material flow control software WAMAS®, you not only optimize your processes but can also significantly reduce your logistics costs at the same time. The software is parameterizable and can be easily configured to match your requirements. It can be used in combination with SSI SCHAEFER software systems and also as a separate picking system in an existing warehouse management system.


The Pick by Light system from SSI SCHAEFER enables you to almost entirely eliminate picking errors. Every storage compartment features a signal lamp on with a display and at least one acknowledgment button. When the picking container reaches the picking position, the lamp shows the employees the correct compartment and the display indicates the correct number of articles to be removed. The removal is then confirmed with an acknowledgment button.

There are three general systems:

  • Pick by Light: one pick face and one illuminated acknowledgment button per removable location

  • Multi Light: one illuminated acknowledgment button per removal location, one central display (Pick face) for multiple removal locations

  • Put to Light: uses the Pick by Light principle. However, the specified quantity is not picked from the position displayed but rather the specified number placed in this position


The Pick by Light system consists of the following components:

  • Control computer with an interface to the higher-level system (host, WMS, etc.)

  • Line controller (the quantity depends on the system size)

  • One pick face per storage location

A pick face consists of the display and control unit. This provides the employee with information about the quantity. Thee employee can acknowledge the completed picking procedure via the illuminated acknowledgment button. Two quantity correction buttons enable the employee to correct the removal quantity during the packing process in accordance with the available quantity.

The Pick by Light system can be easily integrated into existing or planned picking processes and strategies. The system especially designed for use in static racking systems and pallet racks.
