Identifying the Flange Connector Type on a Universal Robots E-Series Robot

In September 2024, Universal Robots updated their e-Series robot models (UR3e, UR5e, UR10e, UR16e) to include an M8 female connector at the tool flange. This aligns the design with the UR20 and UR30 models, helping to reduce flange damage and simplify product compatibility. (UR communication)

Identifying Your Connector Type

If you have an e-Series robot, you can determine the connector type by comparing your robot’s serial number to the table below. If your serial number is higher, your robot has a female flange connector. If it is lower, your robot has a male connector.

All UR12, UR15, UR20 and UR30 robots are equipped with female connectors by default.
