Presence Check of Wood Pallets with Retro-Reflex Sensors for Transparent Objects

The safe flow of goods on roller conveyors in the wood industry requires reliable detection of pallets regardless of their size, design and position. Multi-beam retro-reflex sensors with a special single-lens optic and reflectors are installed on the side of the conveyor line for this purpose. Thanks to its long range, the multi-beam sensor, which works with red light, detects the entire width of the track and thus detects all types of pallets regardless of position – even with recesses and spaces. As soon as even a single beam is interrupted, the sensor switches.
