The Banner SM312CV2 is a high-performance polarized retroreflective photoelectric sensor designed to deliver reliable object detection in challenging environments. Featuring a visible red LED for easy alignment and a sensing range up to 15 meters, this sensor uses a polarized lens system to eliminate false triggers from shiny surfaces. Its rugged housing ensures durability in harsh industrial settings, while the NPN output configuration makes it compatible with a wide range of control systems. The SM312CV2 is ideal for use in packaging lines, conveyor systems, and material handling where accurate object presence detection is essential. Key Features: • Polarized retroreflective sensor with visible red LED • Extended sensing distance up to 15 m with reflector • NPN output (Dark-on or Light-on selectable) • Polarization filter to avoid false readings from shiny objects • Easy alignment using bright red LED light spot • IP67-rated industrial housing for demanding environments • Wide voltage range and fast response time
