In an opposed-emitter setup, the SM31E emits an infrared beam at 880 nm across a 3 m gap to a companion SM31R receiver; beam interruption signals the sensed event. It operates on 10–30 V DC and is available in pre-wired variants for quick installation, with an 18 mm mounting footprint typical of the Mini-Beam family. This emitter belongs to Banner’s Mini-Beam DC Voltage Series and is designed for compact, rugged industrial environments where a dedicated emitter is paired with a receiver to form a reliable through-beam sensor. Applications include packaging lines, part detection on conveyors, end-of-line sensing, and other inline automation tasks requiring a clear, stable beam. \u003c\/p\u003e\u003c\/div\u003e","brand":"Banner","offers":[{"title":"New","offer_id":51676508455214,"sku":null,"price":181.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_f9b569d0-a0d4-474a-816b-cc730584a152.jpg?v=1769551493","url":"https:\/\/plgautomation.com\/products\/banner-engineering-sm31e-photoelectric-sensor","provider":"PLG Automation ","version":"1.0","type":"link"}
