Reach and precision
The EC63 reaches 624 mm, 124 mm more than the UR3e, and publishes ±0.02 mm repeatability against ±0.03 mm. Wider benches and fine electronics assembly favor the EC63.
Speed and force sensing
Universal Robots publishes a 3 m/s maximum tool speed for the UR3e, against 2 m/s for the EC63. The UR3e's built-in ±30 N / ±10 Nm force/torque sensor and continuous final-joint rotation suit insertion and screwdriving.
Weight and footprint
Both arms sit on a Ø128 mm base. The UR3e weighs 11.2 kg and the EC63 13 kg, so both fit on benches, light frames and inside machines.
Programming and connectivity
The UR3e runs PolyScope and supports PROFINET with PROFIsafe, EtherNet/IP, Modbus TCP and ROS/ROS2. The EC63 publishes Modbus TCP/RTU, EtherNet/IP, PROFINET and CC-Link as a slave device, plus RS485/RS232. Both arms are rated IP54.
