The article concludes by reviewing the main advantages of collaborative robots in terms of sustainability and performance, including reducing energy consumption, minimizing material waste, and improving return on investment (ROI). DigiKey offers these solutions designed by Schneider Electric, providing a practical and feasible way to achieve smarter, safer, and more flexible automation.
Collaboration performance for demanding workflows
Lexium collaborative robots support various Industry 4.0 applications that require precision, flexibility, and integrated safety features. Common practical applications include packaging, logistics, automotive production, electronic assembly, semiconductor manufacturing, and life sciences.
Lexium collaborative robots utilize torque sensors and safety features that comply with ISO/TS 15066 standards to safely collaborate with human workers and other robots without the need for physical protective infrastructure. High path precision and consistent motion control enable precise handling and fine assembly. The compact size and high mechanical flexibility help to quickly redeploy between workstations, reduce downtime, and support Just In Time (JIT) and mixed mode production.
Payload range and accuracy
The Lexium Cobot series includes six axle models with payloads of 3, 5, 7, 12, and 18 kilograms, respectively. Each model supports high-throughput workflows and fine mobility accuracy, with repeatability ranging from ± 0.0 to ± 0.03 mm, depending on the payload level.
The Lexium Cobot 3KG (LXMRL03S0000) (Figure 1) is designed specifically for precision tasks such as small part assembly, sample processing, and inspection. Its extension distance is 626 mm and the frame weight is only 12 kilograms, making it easy to integrate into desktop workstations, mobile carts, or compact units.

The Lexium Cobot 5KG (LXMRL05S0000) achieves a balance between motion sensitivity and payload capacity, making it suitable for electronic assembly, light mechanical fastening, and medium load picking and placing tasks. Its 954mm extension distance and 23kg base weight provide sensitive and stable performance in applications that require stable motion control, such as circuit board assembly, connector installation, and testing.
Extend distance and payload to meet demanding application requirements
The Lexium Cobot 7KG (LXMRL07S0000) has an extension distance of 819mm and fast, sensitive motion control capabilities for dynamic pick and place operations. It is typically deployed on packaging and logistics production lines for labeling, palletizing, material handling, and carton making.
The Lexium Cobot 12KG (LXMRL12S0000) and Lexium Cobot 18KG (LXMRL18S0000) models are designed specifically for the handling and assembly of large parts in automotive applications. The extension distances of these systems are 1327 mm and 1073 mm respectively, which can meet the needs of heavy-duty workflows without reducing accuracy.
