Banner Engineering SM312LVAG Mini-Beam Photoelectric Sensor

The Banner Engineering SM312LVAG Mini-Beam Photoelectric Sensor is a polarized retroreflective sensor designed for non-contact object detection in industrial automation, ideal for conveyor systems, packaging machinery, material handling equipment, baggage handling, and automated assembly lines that require reliable presence sensing. It detects reflective targets from 55 mm to 2 m using a visible red LED at 650 nm and operates on 10 to 30 VDC with a bipolar output (one NPN and one PNP) rated to 150 mA, delivering a 1 ms response time for fast, dependable sensing. The unit ships with a 2 m attached PVC cable and features a rectangular Reinforced Thermoplastic Polyester housing with an 18 mm threaded lens, a acrylic lens, and IP67/NEMA 6 protection; it supports panel or bracket mounting across an operating temperature range of -20°C to +70°C, with short-circuit and overload protection to help ensure rugged performance in harsh environments. Common replacements include Banner SM312LV and QS18VN6AF100Q, and this model is part of the MINI-BEAM SM312 family, offering a compact, easy-to-integrate option for machine upgrades, retrofits, or replacements in industrial control systems.
