With an infrared emission at 880 nm, it sends a beam to a compatible receiver (for example SM31R or SM31RL) across up to 30 meters to detect beam interruption in through-beam configurations. Operated from a 10 to 30 V DC supply, the emitter is commonly delivered with a 2-meter pre-wired cable, while longer cable variants are available for installations that require additional reach. As part of the Mini-Beam DC Voltage Series, the SM31EL’s compact form factor and rugged construction suit industrial environments such as packaging lines, conveyors, and automated systems where reliable, non-contact detection is essential. Proper alignment with its receiver is key to consistent sensing, and this emitter is designed to pair specifically with Banner receivers to form a complete sensing solution.\u003c\/p\u003e\u003c\/div\u003e","brand":"BANNER","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51676608135470,"sku":null,"price":73.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_3316e555-99c6-4dd2-a3ef-a2ad48a2b397.jpg?v=1769551502","url":"https:\/\/plgautomation.com\/products\/banner-engineering-sm31el-photoelectric-sensor","provider":"PLG Automation ","version":"1.0","type":"link"}
