Pick-to-Light Module: PTF-L-7


44 mm x 50 mm

The Pick-to-Light (Pick-to-Light) compartment display has a very narrow design and has no display. It does not have a mechanical acknowledgement button itself and is used in the standard version in a Pick-to-Light system for applications where no quantities and no direct acknowledgement on the display are required. With this compartment display, only the removal compartment is signaled (e.g. single piece in Automotiv).

With the PTF-L-7 in standard version, the removal confirmation is usually done via a barcode scanner, RFID reader, PC, etc.. This compartment display can also be used for C-items in combination with a central display in the Pick-to-Light system. In this case all C-shelves of a shelf block are equipped with this Pick to Light display. In addition, a central display with a piece count display and acknowledgement button is mounted on the C-shelf block. Removal from the C-shelf then takes place sequentially itself.

The L-7 directly shows the removal tray and the central display the required number of pieces andis also used for the removal confirmation. The central display can also be used for shortage corrections, inventories and zero passage. The L-7 without sensor can also be used as a target display for sorting processes (put-to-light), whereby the delivery into the compartment is acknowledged or monitored by scanner or Pick-Radar acknowledged or monitored.
