The Task
In car door seal production seals of various lengths must be handled with precision. To ensure correct placement, each seal is guided along a conveyor belt. During transport, the end of the seal must be detected so the conveyor can stop at the exact position for the next step. An optical sensor is required to identify the end of the seal in continuous operation and send a signal to the conveyor belt to stop at the correct position. Once the seal is correctly positioned, it can move on to the next production step.
The Challenge
The door seals are black and reflect very little light, which makes them difficult to detect. In addition, the seals are often round, which further complicates detection.
Our Solution
The FT 50-BH BlueLight photoelectric diffuse sensor reliably detects even dark and shiny objects. Its background suppression ensures stable detection even on a moving conveyor, while the integrated scale makes it quick and easy to fine-tune the settings for optimal performance.
Your Advantages
- Stable detection of black and rounded objects
- Precise and reliable switching with highly light-absorbing objects
- Reliable operation without a reflector – even with challenging shapes and surfaces
- Easy alignment with a clearly visible light spot
- Background suppression for reliable detection on conveyor belts
- Easy background suppression adjustment via integrated scale
- Flexible sensor adjustment via teach-in button, control input, and IO-Link
- Adjustable detection range of 30-300 mm
