Presence Check of Pallets in the Refrigerated High-Bay Warehouse with Through-Beam Sensors
In refrigerated logistics centers, the presence of pallets before and after each transfer position must be known in order to secure material flow between the conveyor line and the high-bay warehouse. Through-beam sensors that function according to the transmitter-receiver principle are attached to the conveyor line for this purpose. While solutions with reflectors do not offer process reliability due to contamination, the through-beam sensors, which can be configured via IO-Link, switch reliably. They do not require a reflector and have a higher power reserve thanks to the through-beam principle – even at temperatures down to –40 °C.
