Banner Engineering SM312LV Photoelectric Sensor, part of the Mini-Beam DC Voltage Series, is a compact self-contained retroreflective sensor designed for small-target detection. It operates from 10 to 30 V DC and provides either NPN or PNP output with selectable dark-on or light-on behavior, using a red LED light source. In retroreflective mode, the SM312LV offers up to 5 meters of sensing range depending on reflector and target, with pre-wired configurations available for quick installation. Common applications include presence detection on conveyors and packaging lines, as well as general automation tasks where a compact, rugged sensor is required.
