I have the ROKO SN04-N, the cables I have are blue, brown, black. looking at your sensor seems like it has a different color. but it looks like its also plug and play.
Checking the website you posted it has a screenshot on how to put it on the printer :: http://prnt.sc/e6dnfc
If I we're you I'd plug it into the board to test it once you're done building everything. Did you change the firmware of the printer?
