The retro-reflex sensor works with a fine laser beam and a reflector. The collimated class 1 laser beam detects objects, e.g., when conducting installation, feed, or presence checks, starting from a size of 2.5 mm, over the entire range. The IO-Link interface can be used to configure retro-reflex sensors (PNP/NPN, NC/NO, switching distance), as well as to output switching statuses and signal values.
