UR5e — Specifications

Overview

The UR5e is a 6-axis collaborative robot arm (cobot) from Universal Robots' e-Series designed for medium-duty tasks that require flexibility, ease of programming, and safe human-robot collaboration. It is commonly used for assembly, pick & place, machine tending, testing, and research applications.

Key Specifications

  • Payload: 5 kg
  • Reach (max): 850 mm
  • Degrees of freedom: 6 (6 joints)
  • Repeatability: ±0.03 mm
  • Robot mass: ~20.6 kg
  • Mounting: Floor, ceiling, wall, or angled (standard flange)
  • Protection class: IP54 (robot arm)

Mechanical

  • Joints / Range of motion: 6 rotary joints; full joint ranges configurable in Polyscope (see official datasheet for per-joint limits).
  • Flange: Standard ISO mounting flange for tool mounting and external connectors.
  • Cable routing: External and partially internal options (specific routing depends on mounting orientation and tooling).

Performance

  • Typical cycle times: Application dependent; UR5e optimized for quick point-to-point moves within its workspace.
  • Motion control: Smooth, force-aware motion with built-in collision detection and joint-level safety limits.

Electrical & Power

  • Power supply: Controller cabinet supplies robot arm; requires standard 120VAC 10A circuit.
  • Peripheral Power Delivery Power accessible at various voltage levels from controller.

Communication & I/O

  • Standard interfaces: Ethernet (TCP/IP), real-time Ethernet options, digital and analog I/O via controller.
  • Fieldbus support: Via UR+ certified modules and I/O interfaces (EtherCAT, PROFINET, DeviceNet, etc.).

Software & Programming

  • Programming environment: Polyscope GUI (teach pendant) with drag-and-drop programming and scriptable URScript.
  • Ecosystem: URCaps for third-party integrations; supports real-time control and ROS interoperability.

Safety & Compliance

  • Safety features: Built-in force/torque sensing for collision detection, configurable safety limits, and safe stop functions when used with the UR controller.
  • Additional Features: A safety laser is installed and can be configured for proximity detection.

Mounting & Installation

  • Mounting orientations: Floor, ceiling, wall, or custom fixtures using the standard wrist/flange. DTC UR5e mounted on rolling cart for flexibility
  • Environmental considerations: IP54 on arm; keep controller and electrical components in appropriate enclosures and follow temperature/humidity requirements from official documentation.

Accessories & Options

  • End effectors: Grippers, vacuum systems, sensors, custom tooling.
  • Controller options: e-Series teach pendant and controller cabinet. Additional UR+ hardware modules available for extended functionality.
