This miniature, self-contained sensor runs on 10–30 V DC and provides a normally sinking NPN output. It emits a visible red beam at 680 nm, and in diffuse (short-range) mode detects small targets from about 2 mm up to 50 mm away (0.1\"–2\"). The QH23SN6D sits among Banner’s family of QH23 sensors—tiny DC devices that cover diffuse, retroreflective, and fiber-optic variants with both NPN and PNP outputs to match different control schemas. With the SN6D suffix, this model is optimized for short-range diffuse sensing and is used in applications where a compact footprint is essential, such as detecting small parts on conveyors, in fixture-based assembly, or in space-constrained packaging lines. The 680 nm red beam provides good visibility during setup, helping align the sensor with the target. Banner’s QH23 line emphasizes ease of installation and consistent performance across surface finishes and colors, making the SN6D a reliable choice when non-contact detection is required in tight spaces. Compatible alternatives in the same family include PNP-output variants like QH23SP6D, enabling designers to select the appropriate wiring and logic for a given control system.\u003c\/p\u003e\u003c\/div\u003e","brand":"Banner","offers":[{"title":"New","offer_id":51676623110446,"sku":null,"price":290.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_cf3d706c-fab5-48eb-90b7-2ef821c19fb9.jpg?v=1769551506","url":"https:\/\/plgautomation.com\/products\/banner-engineering-qh23sn6d-photoelectric-sensor","provider":"PLG Automation ","version":"1.0","type":"link"}
