It operates on 10–30 V DC and provides bipolar outputs (one NPN and one PNP) through a 4-pin M12 integral quick-disconnect (QD) connector, simplifying wiring in control panels and machine frames. This green-light variant, part of Banner’s MINI-BEAM family, supports selectable dark-on or light-on operation so you can tailor sensing to surface contrast, reflectivity, and color. Sensing is performed via a fiber-optic interface, with the detection range determined by the chosen fiber and installation, giving flexibility from short to longer reach depending on the fiber configuration. The SM312FPGQD uses a Green LED light source and is designed for compact automation tasks where fiber-coupled sensing enables access to recessed targets or challenging geometries while delivering reliable digital outputs compatible with standard PLC inputs. The model aligns with Banner’s Mini-Beam portfolio and shares common form-factor and accessory compatibility with other SM312 variants, making replacements and upgrades straightforward in existing systems.\u003c\/p\u003e\u003c\/div\u003e","brand":"Banner","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46273199014122,"sku":null,"price":181.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-074.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/banner-engineering-sm312fpgqd-photoelectric-sensor","provider":"GTG Hardware","version":"1.0","type":"link"}
