The retro-reflex sensor works with a fine laser beam and a reflector. The laser class 1 collimated laser beam detects objects, for instance, when checking installation, feed or presence, starting at a size of 0.75 mm over the entire range. The IO-Link interface can be used to configure retro-reflex sensors (PNP/NPN, NC/NO, switching distance)and to output switching statuses and signal values.
