Conveyor belts are a central element in industrial automation. They transport products continuously through the various process steps. Precise detection of the objects is necessary for downstream stations to work reliably. Products with shiny or colored surfaces that are in motion and have to be detected against changing backgrounds are particularly challenging.
Shiny materials and strong color contrasts pose problems for conventional sensors. Reflections, changes in lighting conditions or color differences can lead to unstable signals. Complex backgrounds such as differently colored conveyor belts or varying structures also increase this risk.
The technology of reflex sensors with background suppression provides a remedy here. It is designed to reliably detect objects regardless of their color or surface finish and at the same time reliably suppress the background.
One example is the wenglor P1MH201, which works with red laser light. It ensures stable operation even when shiny or colored products are transported on the conveyor belt.
Precise object detection on conveyor belts is crucial for smooth automation processes. Reflex sensors with background suppression, such as the wenglor P1MH201, ensure reliable detection even under difficult conditions. With red laser light, stable background suppression and reliable function even with reflections or color variations, they make a decisive contribution to process reliability.
