The Task
In paper production and processing, sensors must detect a wide variety of printed sheets as they move along a roller conveyor. Accurate detection ensures smooth operation and prevents errors in downstream processes.
The Challenge
The varying surface colors, shapes, and structures make it difficult to detect the sheets of paper. They can be black, colorful, high-gloss, or even transparent, as is the case with window envelopes. It is also important that the sensor switches stably and reliably detects the different types of paper sheets without false detections.
Our Solution
The FT 50-BH BlueLight reflex sensor reliably detects paper sheets of varying colors, finishes, and transparencies. Its blue LED technology ensures accurate detection of challenging materials, including black, glossy, or transparent sheets. With precisely adjustable background suppression, the sensor ignores unwanted objects in the background, focusing only on the target sheet. Its compact, rugged housing makes it ideal for installation between the rollers of a conveyor.
Your Advantages
- Adjustable detection range of 30-300 mm
- Precisely adjustable background suppression
- Simple sensing range adjustment with display scale
- Rotatable plug connection
- Reduction of roller conveyor downtime by preventing false detections from background objects
