autoReflAct
autoReflAct stands for automatic Reflector Activation 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 acti
-
vates 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.

The autoReflAct function uses the scanning beam to simulate a photoelectric sensor and thus permits an
activation without additional sensors.
You will find a matching reflector in Accessories, and more are available on request.
