PTL (Pick-To-Light) Intelligent Picking System
How can production lines and warehouse management accelerate manual picking processes and enhance operational efficiency? Integrating Pick-To-Light shelving storage offers an efficient and intuitive solution.
Pick-To-Light is an intelligent system designed to assist manual picking by guiding personnel through electronic displays and indicator lights, enabling quick and accurate identification of items. This significantly improves picking speed and accuracy.
The system supports manual operation and can seamlessly integrate with Warehouse Management Systems (WMS). Upon order generation, the electronic display at the corresponding storage location lights up, clearly indicating the items and quantities to pick. Operators follow these instructions to complete picking and confirmation, thereby accelerating task completion.
Applications and Key Advantages
Pick-To-Light is especially suited for environments demanding fast shipment, high-frequency assembly, or strict logistics timelines. It greatly enhances operational efficiency, reduces errors, and optimizes warehouse workflows, helping businesses build smart warehousing and strengthen logistics competitiveness.
If your production line or warehouse seeks an efficient picking solution, the PTL (Pick-To-Light) system is your ideal step toward intelligent logistics.
The New Revolution in Efficient Picking — How the Pick-To-Light Intelligent Picking System Works

PTL (Pick-To-Light) System Overview
The PTL system uses LED indicator lights and LCD displays to provide picking personnel with fast and intuitive picking guidance, significantly improving operational efficiency and accuracy. Display devices are installed at each workstation and picking aisle and are integrated with the Warehouse Management System (WMS) to instantly track inventory quantity and product types at each storage location.
Automated Picking Process
-
Order Generation: When an order is created manually or automatically, the shelving system receives commands and highlights the items to be picked.
-
Light Guidance: Indicator lights at the corresponding locations illuminate, showing the storage position and quantity required, allowing pickers to quickly locate the correct items and avoid mistakes.
-
Pick Confirmation: After picking the required quantity, personnel confirm completion via a magnetic wristband sensor.
With the Pick-To-Light system, your warehouse can achieve faster picking speeds, lower error rates, and more precise inventory management—moving your logistics operations toward smarter, more efficient workflows.
