The two sensor enclosures can be wired to the Control Unit via a small junction box.
This box is typically installed underneath the conveyor belt and allows for improved
flexibility of mounting Control Unit as the distance is not limited by the sensor cable
length. Typical wiring details for this option are shown in figures below:
