Banner Engineering SME312FVGQD Mini Beam Sensor

The SME312FVGQD Mini-Beam Expert Series fiber-optic sensor from Banner Engineering is a compact, fiber-coupled photoelectric switch that uses a glass fiber optic to deliver a precise, visible green beam for detection in tight spaces. It employs a Glass Fiber Optic sensing mode with a 525 nm emission, and the sensing range is determined by the specific fiber used (no fixed distance is listed for this model). Powered from 10 to 30 V DC, it provides a bipolar output (1 NPN, 1 PNP) and uses a 5-pin M12 quick-disconnect (QD) connector for fast, reliable wiring. As part of Banner’s Expert Series, this model is designed for compact installation in automation tasks where a fiber-delivered beam simplifies sensing in crowded or hard-to-reach areas. Common applications include presence/absence detection on conveyors or in tight fixtures, and other industrial sensing tasks that benefit from fiber-coupled deployment and a QD connection for quick field service.
