The Pick to Light allows the guided collection of small pieces or small boxes, with great efficiency and without paper. It reduces the error rate by 0.10% and increases productivity. It is very suitable when working with a large number of orders, precision pickups, best-selling items, low number of items per order or temporary peaks.

Inside a picking process of an order using pick to light, the user sees where the articles and units per article are located. Each time an element is collected, it is recorded. The order is completed step by step and several users at the same time can fulfill parallel running orders in the same area using different indicadors.

The Put to Light allows you to separate a group of articles by its orde automatizing the order preparation of articles distributed on several places in the warehouse.

The displays are connected to the warehouse management software allowing to have the inventory in real time

Electrotec has developed its own picking system based on more than 10 years of experience installing products from other manufacturers. The most common errors have been taken into account in our design. The result is robust, easy to install, easy to manage (e.g. with a web browser) and adaptable.  We are very competitive with handheld displays.


AHigh productivity in high-demand environments with three or four workshifts, where a production stop can be critical. The robustness of Electrotec picking systems resides in the connection technology used, where if a cable is disconnected the production does not stop.


The system configuration and monitoring can be done through the integrated webserver of DPI controller. Each controller can handle up to 500 displays. If a display has any problem, it appears in a different colour easy to identify and can be changed.


Electrotec’s Pick to Light libraries allow easy integration with any type of management software, reducing the implementation time of the digital picking solution.

Electrotec developed a flexible Pick to Light that incorporates peripherals such as barcode readers, handheld detection or scales.
