The model designation indicates a DC-powered variant within the 871C line, designed for non-contact metal sensing in compact spaces. Used for part-detection and position-sensing tasks on conveyors, packaging equipment, and automated assembly cells, it helps trigger control logic without mechanical wear. The 871C family is built for rugged factory environments and offers straightforward mounting via threaded barrels and a range of termination options to fit typical control panels and field wiring. Applications include verifying presence of metal parts in feeds and chutes, signaling downstream machinery in automated lines, and supporting reliability improvements over mechanical switches by eliminating contact wear. Because exact electrical specifications vary by variant, consult the Rockwell Automation datasheets and cut sheets specific to 871C-D5A18 to confirm supply voltage ranges, current ratings, and output type compatible with your controller and wiring scheme. In practice, this sensor pairs with standard PLC inputs and control circuits in mid-range automation projects, delivering repeatable metal-detection performance in a compact form factor.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":51657410085166,"sku":null,"price":58.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_6aadb701-db47-4bc7-a751-ed3c77745de4.jpg?v=1769468680","url":"https:\/\/plgautomation.com\/products\/allen-bradley-871c-d5a18-proximity-switch","provider":"PLG Automation ","version":"1.0","type":"link"}
