ivation and permits an activation without
additional sensors. This is achieved by directing the scanner with reduced scanning beam
towards a reflector mounted behind the conveyor path. As long as the scanner is targeted
at the reflector, the reading gate remains closed. If, however, the reflector is blocked by an
object such as a container with a bar code label, the scanner activates the read procedure,
and the label on the container is read. When the path from the scanner to the reflector has
cleared, the read procedure has completed and the scanning beam is reduced and again
directed onto the reflector. The reading gate is closed.
Notice!
You will find a matching reflector in Accessories, and more are available on request.

The
autoReflAct
function uses the scanning beam to simulate a photoelectric sensor and
thus permits an activation without additional sensory mechanism.
