Banner Engineering SMW915D Photoelectric Sensor

SMW915D is Banner Engineering’s VALU-BEAM diffuse‑mode photoelectric sensor designed for reliable presence/absence detection of small targets on conveyors, production lines, and packaging systems. It runs on 12–28 VAC/DC, provides an SPDT electromechanical relay output, and ships with a 2‑meter cable and a red 650 nm light source, making it well suited for environments where clear optical feedback is required. In diffuse mode it detects targets at up to 760 mm, using a 1.5 mm sensing spot that focuses about 38.1 mm in front of the lens, contributing to repeatable performance on matte or lightly colored surfaces; the sensor features a rapid 20 ms response time. This SMW915D variant weighs about 1.0 lb and is listed as discontinued by Banner, though related models in the SMW915 family (such as SMW915DQD and SMW915DSRQD) continue to appear in distributor catalogs with similar voltage and output specifications. For installers seeking a compact, fixed‑output sensor with straightforward wiring, the SMW915D offers a solid baseline sensing solution without the need for complex configuration.
