Hello,
I am using four 5V 30mW Laser Photoelectric Switches (RB-Dfr-330) on a robot prototype. They are all supplied by the same regulated 5VDC source. I have just recently started using them. One of the laser emitters initially worked, but has now stopped producing a beam. The laser’s on-board indicator LED still turns on when the laser is plugged in, as it should.
The three other lasers are still working perfectly, so I haven’t been able to find any cause for this problem. The laser may have been defective. Please advise.
Thank you very much.
