Universal Robots UR18g-950

The UR18g-950 is a six-axis collaborative robot arm from Universal Robots' Generation 7 g-Series, with an 18 kg payload and a 950 mm reach. It is IP65 rated, reaches a maximum TCP speed of 4 m/s, and repeats poses within ±0.05 mm per ISO 9283. An integrated force-torque sensor and power, I/O and Ethernet connectors at the tool flange let cameras, sensors and end effectors be connected without external cabling.

  • Average power consumption is 350 W; the 570 W figure is the maximum.
  • Noise level is below 55 dB(A).
  • Tool flange mechanical interface is ISO 9409-1-50-4-M6; mounting is possible in any orientation.
  • Tool flange force-torque sensor ranges are ±150.0 N and ±10.0 Nm, with precision ±7.5 N and ±0.2 Nm.
  • Tool flange connectors: M8-8 A-coded I/O, M8-4 A-coded power, M12 X-coded 1 gigabit Ethernet (IEC 61076-2-109), plus an optional SP7 Smart Panel interface.
  • Status is indicated by a light ring at the robot base.

Safety

  • 23 configurable safety functions are stated.
  • TÜV Rheinland certified to EN ISO 13849-1 and EN ISO 10218-1, and RoHS compliant.
  • North American requirements: TÜV Rheinland cTÜVus and UL 1740.
  • The tool flange provides a safety digital input on the M8 I/O connector and the SP7 interface provides one safety input.
