Banner Engineering SM312LVAGQD Photoelectric Sensor

The Banner Engineering SM312LVAGQD Photoelectric Sensor is a compact MINI-BEAM DC voltage sensor designed for extended-range polarized retroreflective detection. Operating on 10–30 V DC, it provides two outputs in a bipolar configuration: one NPN and one PNP, enabling sinking or sourcing loads from a single device. The QD variant features a 4-pin M12 integral Quick Disconnect connector for fast field wiring. In polarized retroreflective mode, the sensor detects a reflected beam from a reflector up to 2 m away, with a practical sensing range starting at 50 mm, making it suitable for small parts on conveyors and packaging lines. The LVAG designation identifies extended-range polarized retroreflective sensing, and this unit is commonly used with Banner’s retroreflective targets, typically paired with a BR T-3 reflector for reliable operation. This self-contained sensor belongs to Banner’s MINI-BEAM DC Voltage Series, offering reliable performance in tight spaces while delivering configurable outputs that support both dark-ON and light-ON operation depending on how it’s wired. Typical applications include presence or gap detection on conveyors, precision edge detection in assembly lines, and short-range positioning tasks where accurate retroreflective sensing on reflective surfaces is required.
