Banner Engineering 3M312LV Photoelectric Sensor

The Banner Engineering 3M312LV Photoelectric Sensor, a Mini-Beam DC photoelectric sensor, is a compact device designed for reliable presence/absence detection in tight spaces. Operating from 10 to 30 V DC, it offers NPN and PNP outputs to suit a range of control systems, and it is configured for retroreflective sensing with a maximum range up to 5 meters depending on target and variant. The catalog entry 25618 identifies this model as the SM312LV within Banner’s Mini-Beam lineup; distributors list retroreflective versions with 5 m ranges and pre-wired cabling, and a M12 4-pin quick-disconnect (QD) version is available in AGQD variants for quick field connections. This small sensor is commonly used for line- and packaging-detection tasks where space is limited, and its 10–30 Vdc supply tolerance simplifies integration with standard industrial controllers. Banner’s Mini-Beam heritage emphasizes fast response and straightforward alignment, helping ensure consistent part-detection performance across manufacturing environments.
