Universal Robots UR20-1750

The UR20-1750 is a six-axis collaborative robot arm with a 1750 mm reach and a 20 kg payload, extendable to 25 kg under boundary conditions. It is programmed through a 12-inch touchscreen running the PolyScope graphical interface and carries I/O, 12/24 V power and RS-485 at the tool flange through an M8 8-pin connector. The arm has an IP65 rating and a Cleanroom Class 4 classification, and the control box supports Modbus TCP, EtherNet/IP and PROFINET.
