Overview
The Banner SME312CVQD MINI-BEAM photoelectric sensor is a compact, self-contained convergent-mode detection device designed for precision industrial automation applications. This unit combines visible red 650 nm wavelength light with a tightly focused 16 mm focal point to deliver a precise 1.3 mm diameter sensing spot. Operating on 10–30 VDC input, it offers bipolar output with both NPN and PNP configurations, making it easily adaptable to most control systems. The SME312CVQD is a standard in manufacturing, packaging, and assembly environments where accurate part detection and position verification are critical.
