Engineering suggestions require suitability checks for your installation.
Detect clear bottles or transparent packages moving through a compact machine station.
Pair the sensor with the specified reflector where required, and validate the target, alignment and 80–500 mm range on the installed machine.
Monitor package passage at a conveyor or packaging station.
Select Light-ON or Dark-ON logic and confirm electrical and optical conditions during commissioning.
