I am looking for a sensor that is PNP 24V that can sense distance up to 2m, and have had the best luck with lasers. We only need a digital out so instead of dropping a thousand on Keyence LR-T sensors each time production breaks them does anyone know of a sensor with configurable distance and digital out? Unfortunately we need to read white on white, so that rules out the standard photo eyes. We've attempted beams and reflectors but of course with 2 parts to each of those options they break twice as often.
