Key features and practical notes

• Diffuse sensing to 380 mm makes the SM312DQD suitable for presence/part detection where reflective surfaces are used.
• Dual (bipolar) outputs let you wire either sourcing or sinking logic without changing the sensor model.
• Robust protection and IP67 rating support washdown and harsh‑environment installations when mounted correctly.
• 4‑pin M12 QD simplifies replacement and integration with standard industrial cabling and quick‑disconnect harnesses.
