It operates from 10–30 V DC and provides two discrete outputs (bipolar): one NPN and one PNP, with a 2 m pre-wired cable for straightforward integration, and it uses a 650 nm red LED with an acrylic lens for visible-beam sensing. The rectangular thermoplastic housing (18 mm diameter, M18 mount) is IP67 and NEMA 4X rated for harsh environments. Key specs include 1 ms response time, 100 ms power-up delay, 300 µs repeatability, operating temperature -20 to 70 C, and humidity up to 90% at 50 C, with light\/dark operate and indicator LEDs to confirm status. Common applications include part detection on conveyors, presence sensing in packaging lines, and other automation tasks where a compact, polarized retroreflective sensor is advantageous. Sensing mode is polarized retroreflective with a 650 nm visible red beam and LED indicators to verify status.\u003c\/p\u003e\u003c\/div\u003e","brand":"Banner","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51676608692526,"sku":null,"price":51.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_e93915d2-e1cd-4bba-b9ff-0278bd9986a1.jpg?v=1769551502","url":"https:\/\/plgautomation.com\/products\/banner-engineering-sm312lvag-polarized-retroreflective-sensor","provider":"PLG Automation ","version":"1.0","type":"link"}
