It is a DC-powered sensor rated for 10–30 V DC and drawing up to 150 mA, with a normally open, PNP sourcing output (unshielded). The 871C-P4R12 features an 18 mm-diameter tubular housing and a nominal sensing distance around 4 mm for this variant. 871C sensors are designed for rugged environments and, in many examples, carry IP67 protection for ingress and dust resistance. The device is a tiny tubular sensor well suited for mounting in confined spaces on conveyors, tooling, and automation equipment where full-size sensors won't fit. Common applications include presence sensing and position detection on conveyors, small robotics, and other machinery requiring compact metal-detection in tight spaces. The Ser. B variant of this model is specifically noted for a 4 mm sensing distance. \u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":51657240609070,"sku":null,"price":72.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_57b257e1-dd5a-462f-ad44-0390e3bf22fc.jpg?v=1769467055","url":"https:\/\/plgautomation.com\/products\/allen-bradley-871c-p4r12-inductive-proximity-switch","provider":"PLG Automation ","version":"1.0","type":"link"}
