Omron electronic components are basically from Europe and they have on wheels there new high performing optical sensor that will be more reliable in identifying mirror,   transparent or diffused surfaces.  Omron B5W  light convergent reflective sensor will be detecting targeting Objects that are more reliable for general reflection through the sensors.

These sensor designing will be a lawyer the object to challenge all those traditional sensors that was transparent cups and glasses in the vending machines . The B5W can detect objects over a maximum distance of 70mm and provides an analogue output signal.
