For applications involving luminescent and fluorescent particles invisible to the human eye, Rockwell Automation has introduced the Allen-Bradley Bulletin 45LUM luminescence photoelectric sensor. By emitting ultraviolet light, this sensor detects visible light reflected from objects regardless of the background or surface.
The sensor can detect clear labels and invisible registration marks. It can also verify tamper-resistant seals and adhesives. Equipped with a push-button teach set-up and an option to remote teach, the company claims the sensor has an operating distance of up to 50mm and one light-operated discrete output. The self-contained sensor has a high-definition light spot for accurate alignment and positioning. It also features a rotatable QD connector and multiple mounting-bracket options for installation flexibility.
