It operates from 10–30 V DC and provides a configurable NPN\/PNP output (bipolar: 1 NPN, 1 PNP) with a pre-wired 2 m (6.5 ft) cable for straightforward integration into standard control circuits. As part of the Mini-Beam DC Voltage Series, the SM31R specifies a 3 m sensing range for the opposed receiver configuration, making it suitable for tight-space sensing on conveyors, packaging lines, and other compact automation layouts where precise presence\/absence detection is required. This receiver is designed to pair seamlessly with Banner’s emitters and accessories to form a complete, space-saving short-range optical sensing solution. \u003c\/p\u003e\u003c\/div\u003e","brand":"Banner","offers":[{"title":"New","offer_id":51676607742254,"sku":null,"price":130.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_de31291f-88c4-41d3-b603-c9b9adf78871.jpg?v=1769551502","url":"https:\/\/plgautomation.com\/products\/banner-engineering-sm31r-photoelectric-sensor","provider":"PLG Automation ","version":"1.0","type":"link"}
