The OMRON F3S-B122P-D is a safety light curtain receiver unit that establishes an infrared sensing field to protect personnel from hazardous machinery. Field interruption triggers an immediate stop signal to the machine. This receiver operates at a sensing distance of 0.3 to 5.0 meters and delivers selectable optical resolution (30 mm, 50 mm, or 75 mm) to match protection requirements ranging from hand to body coverage. The unit ships with 12 optical axes configured for 30 mm resolution across a 300 mm protective height. IP65-rated metal enclosure with M12 connectors ensures durability in industrial environments.
