SCARA Robot Series

Aug. 22, 2020

The LS3-B SCARA and LS20-B SCARA robots include a batteryless encoder, a lower cable duct profile that is ideal for hard to reach work cell layouts, built-in camera cable for easy vision system setup, and a top-of-arm layout for enhanced usability. 


Epson’s LS3-B SCARA robots are perfect for factories looking for maximum value without giving up performance. They are ideally suited for applications such as assembly, pick and place, kitting, dispensing, and more. The LS20-B SCARA robots are perfect for higher payload applications such as large component pick and place, machine load/unload, palletizing, mechanical assembly, industrial part transfer, and more. Epson’s LSB-Series robots are used in automotive, medical, lab automation, electronical components, consumer electronics, and industrial markets. Both robots include Epson proprietary Quartz MEMS technology, a hardware and software system that combines force feedback and position for improved servo performance, thus reducing residual vibration. ISO 4 Cleanroom models are also available.


The LS3-B SCARA robot has a payload of 3kg and a 400 mm reach, while the LS20-B has a 20 kg payload and available reach of 800 mm and 1,000 mm. The LS3-B comes in a new compact size with reduced cable height. Both models include a built-in camera cable, feature a new top of arm layout for easy equipment mounting, and are compatible with the new RC90-B controller, a single controller with wiring options for both PNP and NPN. Similar to other robots in the LSB-Series, the new models include a batteryless encoder designed to minimize downtime and help reduce the overall cost of ownership.
