It operates from a 10-30 V DC supply and provides a bipolar dual-output: 1 NPN and 1 PNP, enabling both sinking and sourcing logic from a single device, with a 4-pin M12 integral quick-disconnect (QD) connector for simple field wiring. The sensing range spans from 10 mm to 3 m, using polarized retroreflective mode to improve performance with reflective labels, metal parts, or glossy targets, and making it well-suited for environments where ambient light can interfere with detection. As a compact, self-contained sensor, the SM312LPQD is commonly used for position sensing, presence detection, and verification tasks on small-format parts and on busy production lines where space is at a premium.\u003c\/p\u003e\u003c\/div\u003e","brand":"Banner","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51676608758062,"sku":null,"price":61.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_d12e9aa5-7217-4b32-9cc6-17df789a0733.jpg?v=1769551502","url":"https:\/\/plgautomation.com\/products\/banner-engineering-sm312lpqd-photoelectric-sensor","provider":"PLG Automation ","version":"1.0","type":"link"}
