The Banner sensors just use current sourcing, so it should be safe just to hook the Brown and Blue wires up to the battery as you would normally, and put the white wire to the EduRobot digital input (+).
The manual says the sensors need 10-30V DC to operate normally, so you might need to use 2 9V batteries connected in series for this to work.
Basically:
1. Connect the (+) terminal of one 9V battery (Battery1) to the (-) of the other 9V battery (Battery2).
2. Connect the Blue wire to the unused (+) terminal on Battery2.
3. Connect the Brown wire to the unused (-) terminal on Battery1.
4. Connect the white (or black) wire to the (+) on the EduRobot digital input.
