The patented etaLINK 3000 system was developed for inductive charging of industrial vehicles within the area of mobile robotics. With our design, the chargers take into account the intelligence and autonomy of the new generation of robotics systems. They can be easily and independently installed and provide the vehicle with all relevant data. The absence of mechanical charging contacts makes it easy to integrate charging the battery into existing processes and thus an intermediate charge of the batteries is possible. This saves time and eliminates the potential dangers posed by open contacts. The etaLINK charging systems are maintenance-free and enable uninterrupted operation over many years.


The contactless charging solution for AGV’s, robots and forklifts in industrial environments. Simply stopping your vehicle at the charging position will start your charging process. Thanks to the contact free design, the system may be installed whereever your process requires. There are no trip hazards and charging will start within less than a second. For optimized charging of Lithium batteries a CAN- interface to communicate with your vehicle components is part of the system.
