It features a 2 mm sensing distance and a 73.0 mm probe length, orange color code, and a normally open source output (PNP) via Micro QD (DC) connections. The device operates on 10–30 VDC. Designed to mount inside the cylinder port to sense the piston within the sensing zone and output a signal when the piston is in range, it is part of the 871D series of hydraulic cylinder position sensors. Typical applications include hydraulic cylinder piston-position sensing in automated manufacturing equipment, machine tools, and material handling systems, where precise end-of-stroke or mid-stroke detection informs control logic and sequencing.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51657409134894,"sku":null,"price":1305.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_a8b793d5-a75e-4dd2-9b97-7cdb5f222ea4.jpg?v=1769468665","url":"https:\/\/plgautomation.com\/products\/allen-bradley-871d-dw2np730-d4-cylinder-position-sensor","provider":"PLG Automation ","version":"1.0","type":"link"}
