This 18 mm diameter sensor features a stainless‑steel barrel and a plastic face, combining durability with a compact footprint for mounting in confined locations. It runs on a 3‑wire DC supply from 10 to 30 V and delivers a PNP normally open (NO) switch output via a Mini QD connector, making it easy to wire into standard control circuits. With a 5 mm sensing distance, it detects metal objects within close range while resisting non‑metal interference, a common requirement in automated lines, conveyors, feeders, and end‑of‑travel sensing. The 871T series is widely used in factory automation for position sensing and machine monitoring, offering a robust, long‑life sensing solution where metal presence must be confirmed without physical contact. Applications include part presence detection on assemblies, conveyor stop\/start interlocks, safeguarding interfaces on automated equipment, and general metal detection tasks in packaging, material handling, and manufacturing environments.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51657408053550,"sku":null,"price":232.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_ac713b9e-4b91-4396-90ac-352e2678faf9.jpg?v=1769468654","url":"https:\/\/plgautomation.com\/products\/allen-bradley-871t-l5j18-inductive-proximity-sensor","provider":"PLG Automation ","version":"1.0","type":"link"}
