The Banner Engineering SM312L infrared retro-minibeam photoelectric sensor is a compact Mini-Beam unit designed for retroreflective detection, using an infrared beam and a reflector to sense targets. It provides NPN and PNP outputs and can be configured for dark-on or light-on operation, with a retroreflective sensing range up to 5 m (16 ft). This model is built for tight spaces in industrial setups and is well suited to detecting small parts where a reflector is employed. As part of Banner's MINI-BEAM family, the SM312L delivers reliable infrared sensing in a small footprint for compact automation applications.
