Banner Engineering SM312DQD-26834 Mini-Beam Photoelectric Sensor

The Banner Engineering SM312DQD-26834 Mini-Beam Diffuse Photoelectric Sensor is a compact, rugged detector that uses an infrared beam and a 380 mm diffuse sensing range to detect reflective targets in tight spaces, ideal for space‑constrained conveyor, packaging, and machine‑cell applications. It operates on a 10–30 V DC supply and delivers a bipolar output (1 NPN and 1 PNP), enabling straightforward interfacing with standard controllers and PLCs without extra adapters. The sensor features a 4‑pin M12 integral quick‑disconnect (QD) connector for secure, plug‑in wiring and is rated IP67 (NEMA 4X) to withstand dust, moisture, and washdown environments common on manufacturing floors. Catalog 26834 identifies this specific SM312DQD diffuse sensor within Banner’s MINI‑BEAM family, combining a small footprint with dependable performance for presence or object-detection tasks on inline equipment, conveyors, and packaging lines where precise sensing is required.
