Banner Engineering Corporation SM312LVAG Sensor

The Banner Engineering SM312LVAG Mini-Beam DC Voltage Series sensor is a compact, self-contained photoelectric sensor designed for extended-range polarized retroreflective detection. Housed in a thermoplastic rectangular body with M18 mounting, it carries IP67 and NEMA 4X ratings for rugged industrial environments. It operates from 10 to 30 V DC and ships with a 2 m integral cable (LVAG suffix) in a 4-wire configuration to support power and two switching outputs. The device provides two switching outputs in a bipolar arrangement—one NPN and one PNP—so you can interface with either sinking or sourcing control logic. For extended-range polarized retroreflective sensing, the SM312LVAG detects targets from 10 mm up to 3 m, depending on reflector and ambient conditions, and is compatible with Banner’s BRT-3 reflector for reliable detection. The Mini-Beam family emphasizes a small footprint suitable for tight installations on conveyors, pick-and-place, or packaging lines, with straightforward mounting and durable construction that holds up to industrial use. Typical applications include part presence detection, stop/start sensing on small parts, and alignment checks in automation sequences, where a compact, DC-powered sensor with both PNP and NPN outputs and a 2 m cable can simplify wiring and integration.
