It emits an infrared beam at 880 nm and operates on 24 to 240 VAC, while the receiver provides the switching output; the emitter itself has no external output. The rugged, epoxy-encapsulated 18 mm barrel-style housing is rated IP67 and meets multiple NEMA standards (1, 2, 3, 3S, 4, 4X, 12, 13), making it suitable for harsh industrial environments. Typical installations support 2 m pre-wired cables or longer 9 m (30 ft) variants, with QD options via the QDP suffix to simplify connections; Banner also offers compatible Mini-Beam configurations for extended ranges and applications such as object detection, part verification, and conveyor sensing in dusty or moist environments.\u003c\/p\u003e\u003c\/div\u003e","brand":"BANNER","offers":[{"title":"New","offer_id":46267283341546,"sku":null,"price":102.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-073.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/industrial-sma31e-mini-beam-photoelectric-sensor","provider":"GTG Hardware","version":"1.0","type":"link"}
