Pick-by-Light Module: PTF-OL-1
PTF-OL-1
5.7 inches x 2 inches
The new PTF-OL-1 pick-by-light module brings even the graphic display up to the latest technical standard. The OL-1 display features a larger, modern graphic display with OLED technology, which ensures a crystal-clear display of process-relevant information. The entire pick-by-light system is now even more attractive.
The abbreviation OLED stands for "Organic Light Emitting Diode," which, unlike LCD panels, consumes less energy and does not rely on external backlighting. Sharper contrasts and thus optimal visibility of the information displayed from every angle ensure greater safety during error-free picking processes. In addition, the module is equipped with the proven features. The oval, two-part eye-catching light (2×7 colors) allows two pickers to work in the same zone, and the graphical Pick by Light display can show additional information, such as item numbers or short descriptions, in multiple lines and different font sizes.

The PTF-OL-1 module can be equipped with additional options. These include acknowledgment via LTouch (light touch of the indicator light) or completely touchless acknowledgment via sensor (QRS motion sensor). A special highlight is an external input (available as an option) for connecting buttons or signal transmitters directly to the pick-by-light module. This can be used to query fill levels, receive status messages from the conveyor system, or integrate external acknowledgment signals.
Why different system names?
pick-by-light
The pick-by-light method is a classic picking method that uses compartment displays. The pick-by-light display shows the quantity to be picked directly at the storage compartment. The pick-by-light system usually receives confirmation of the pick by pressing a button on the module.
pick-to-light
The term is often used in English-speaking countries instead of pick-by-light. The pick-to-light method is a Multi-Order-Picking that focuses on distributing items that have just been picked to different orders. The method is typically used with a picking cart (Pick-by-Cart).
put-to-light
The put-to-light method clearly defines the distribution of goods to the target compartments. A classic example of this is replenishment in a flow rack.
