Sensor perforation detection

Machine Design

Happy weekend, everyone!

I was looking for perforation detection solutions using fiber optic amplifiers and came across this photoelectric sensor specifically designed for transparent label films (FUWEI FGU07)

I have tested infrared sensors before, but I know they can present some inconsistencies with highly transparent films. I got curious and bought it to test out since it was quite cheap. Has anyone used a similar sensor?

Cheers!

Personally, I prefer laser pinpoint sensors to; they work with all types of film—white, black, color, or transparent—and ensure perfect detection. Best of all, they don’t require a reflector.
You just need to add a small lens to the end of the fiber optic cable to focus the laser and produce a 0.3mm beam.

Hi @Roland,

Thanks to you and @Eldi for sharing these links! I will definitely order these and test (the price is very good too).

I’ll share the results here. Thanks again!
