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.
NOTICE
Suitable reflectors are available, see chapter 14.5 "Accessories – Reflectors and reflective
tapes".
As long as the scanner is targeted at the reflector, the reading gate remains closed. If, however, the reflec-
tor is blocked by an object such as a container with a bar code label, the scanner activates the read proce-
dure, 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.
