Counting Reflective Rings

Reflective surfaces are one of the more challenging types of objects to sense with a traditional photoelectric sensor. Cylindrical reflective objects are especially difficult to sense due to the light reflecting differently on the various parts of the curved surface of the object.

Description

The WORLD-BEAM Q12 in retroreflective mode detects shiny metal rings as they pass on a conveyor and then sends the data to a counting device.

Because the reflector distorts the beam it returns to the emitter, the sensor can distinguish between the beam reflecting from the rings and the beam reflecting from the reflector.
