Banner Engineering SME312LPCQD Photoelectric Sensor

SME312LPCQD is Banner Engineering’s Mini-Beam Expert Series photoelectric sensor designed for polarized retroreflective detection at a 1-meter sensing range. It operates on a 10–30 V DC supply and offers a bipolar output configuration with one NPN and one PNP transistor, enabling both sinking and sourcing logic from a single device. The 5-pin M12 integral quick-disconnect (QD) connector provides reliable, field-serviceable cabling, ideal for industrial environments. This model uses a visible red 650 nm sensing beam and is rated IP67 for dust and water ingress, with a NEMA 4X enclosure rating for rugged applications. The SME312LPCQD is configured for retroreflective sensing with polarized detection, meaning it can reliably distinguish targets from background reflections when used with Banner’s reflective accessories. In practice, the device supports common PLC input wiring thanks to its bipolar outputs, making it suitable for compact automation booths, packaging lines, and material-handling setups where space is at a premium and a reflector defines the sensing field. Banner’s Mini-Beam family emphasizes compact footprint and robust performance in harsh environments, pairing simple 10–30 V DC power with a straightforward 5-pin Euro-style QD connection for quick installation.
