Serial numbers

Understanding Universal Robots serial numbers

Last modified on Feb 24, 2025

General SN:

UR20 / UR30 SN:

OEM vs. Standard Robots:

(Only applicable for e-series)

How to differentiate standard robots from OEMs is from the SN structure:
SN structure: YYYY (year) G (generation) S (size) XXXXX (production number).

The number from the OEM starts with:

  • 90000 if DC OEM
    • Eg.: 20215590001
  • 80000 if AC OEM 
    • Eg.: 20215580001

The control boxes have changed for both CB3.1 and e-Series in June 2019: https://www.universal-robots.com/articles/ur/documentation/product-alert-control-box-updates-june-2019/

UR10e 12,5Kg vs. 10Kg:

The UR10e - 12,5Kg has a different number than the old UR10e - 10Kg:

  • UR10e 10Kg: YYYY (year) 5 (e-Series Generation) 0 (10Kg) 00000 (Production Number)
    • Eg.: 20215000001
  • UR10e 12,5Kg: YYYY (year) 5 (e-Series Generation) 2 (12,5Kg) 00000 (Production Number)
    • Eg.: 20215200001

  • The CB3.1 controller is a bit different from the CB3.0 controller due to the following
    • It runs of a USB version with more process power
    • It runs of a USB key (USB 3.0) where all former CB-versions runs of a flashcard

CB2 and CB3 looks the same on the outside. However, on the inside there are many differences.  Here is a quick overview of the differences.

  • True absolute magnetic encoders
    • Old type UR uses incremental optical encoders
    • Each mark on encoder disk is unique, making it unnecessary for battery backup
    • This results in no referencing needed at power up and other advantages
  • Safety Control Board (CB3) replaces Masterboard(CB2)
  • Additional I/O, Total is now 16 inputs and 16 outputs in control box
    • 8 inputs and 8 outputs are easy configurable as Safety signals or general-purpose signals
    • Connectors replaces screw terminals
    • Connectors are hardcoded, avoids incorrect insertion
  • UR Safety 3.0, Patented adjustable Safety System
    • UR Safety 3.0 is certified by TÜV
    • All safety functions are safety rated to Performance Level d (PLd)
                Tested in accordance with:
                  EN ISO 13849:2008 PLd
                  EN ISO 10218-1:2011, Clause 5.4.3
  • Software improvements
    • Program execution will continue from where it stopped (result of the true absolute encoder)
    • Realtime performance, part of software re-written
    • Conveyor tracking, decoding of encoders now runs at 40kHz (CB2: 125Hz)
    • Singularity, speed is reduced around singularities, so the robot is able to move through singularities
