As part of the 871L family, it provides a compact, wear-free alternative to traditional mechanical limit switches in machines and conveyors. This model senses metal targets at a 15 mm distance, enabling precise detection in tight spaces and at close travel limits. Typical applications include end-of-travel sensing, position monitoring, machine guarding interfaces, and alignment checks across manufacturing, packaging, and material-handling equipment. The 871L family is built to withstand rugged factory environments while delivering reliable, contactless operation, reducing maintenance associated with mechanical limit switches. The XNB15Q40 designation identifies this model within the 871L lineup, signaling inductive proximity sensing performance in a small form factor that can be integrated with standard automation controls and sensor networks used in industrial applications. \u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51657408676142,"sku":null,"price":145.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_5254df00-d6dc-456d-9753-e438a2c20de6.jpg?v=1769468661","url":"https:\/\/plgautomation.com\/products\/allen-bradley-871l-xnb15q40-proximity-limit-switch","provider":"PLG Automation ","version":"1.0","type":"link"}
