Banner Engineering SM312LVQD Photoelectric Sensor

Banner Engineering SM312LVQD Photoelectric Sensor is a compact Mini‑Beam DC sensor designed for polarized retroreflective sensing out to 5 meters. It operates from 10–30 V DC and uses a 4‑pin M12 Euro‑style quick‑disconnect (QD) connector for fast, field‑install wiring. The sensor provides a single NPN/PNP output configurable for dark‑on or light‑on operation, enabling straightforward integration with standard control logic on conveyors, packaging lines, and automated equipment. As part of Banner’s Mini‑Beam DC Voltage Series, the SM312LVQD employs polarized retroreflective sensing to improve performance against glossy backgrounds, making it well suited for setups that rely on a reflector to establish a reference target. Its compact form factor and QD configuration help simplify installation and maintenance in space‑constrained environments, where quick disconnects and reliable detection are essential. This model is widely cataloged and available through distributors such as Mouser, DigiKey, and Farnell, underscoring its status as a drop‑in component for established Banner Mini‑Beam systems.
