Banner Engineering Corporation SMA31E Photoelectric Sensor

The Banner Engineering SMA31E Mini‑Beam emitter is a self‑contained infrared photoelectric sensor designed for opposed‑emitter operation with a 3 m sensing range, making it well suited for simple object detection on conveyors and packaging lines. It runs from 24 to 240 VAC on a 2 m pre‑wired cable and comes in an IP67 enclosure with a rugged NEMA 1/2/3/3S/4/4X/6/12/13 rating for harsh environments. As an emitter, it provides no output of its own and is intended to be paired with a Banner Mini‑Beam receiver to form a complete sensing system, with the infrared beam around 880 nm. This model is part of Banner’s MINI‑BEAM AC Voltage Series, specifically the SMA31E Opposed Emitter configuration.
