Dear,
The UR5 robot has a tool connector on its toolflange. But I have a hard time finding a mating connector. An American company is listed as a reference, but buying it here in The Netherlands is troublesome. Does anyone have an adress / website / company name where I can purchase these mating connectors? I prefer Farnell, mouser EU or rs-online…
Or if you have a spare mating connector and are willing to sell 
Kind regards,

The Tool cable is available for purchase from a UR distributor.
It has part number 173101 ( Cable for tool external )
You can also purchase the cable with connector from Phoenix Contact, P/N 1404193.
I contacted a local supplier, Olmia Robotics, which carry the cables in stock. But they did mention the P/N was not correct… Anyway, I have one, thank you!
PS
The Phoenix Contact cable checks out, too.
