{"product_id":"allen-bradley-871tm-dr5ne18-h2","title":"871TM-DR5NE18-H2","description":"\u003ch2\u003eOverview of Allen Bradley 871TM-DR5NE18-H2\u003c\/h2\u003e\n\nThe Allen Bradley 871TM-DR5NE18-H2 is a 2-wire intrinsically safe inductive proximity sensor designed for hazardous environment detection and control. This 18 mm barrel-diameter sensor offers a 5 mm sensing distance and operates on 10 to 31.5 VDC input voltage, drawing between 2 and 25 mA load current. Built for Zone 0, Zone 1, and Zone 2 hazardous locations, this sensor provides reliable non-contact object detection in explosive atmospheres where safety certification is mandatory. The H2 suffix indicates a 2-meter ToughLink cable connection, engineered for industrial durability and resistance to oil, chemicals, and physical stress. As part of the 871TM series, this sensor has been discontinued by Rockwell Automation, with the 871C-DH5M18-D4 NAMUR sensor serving as the recommended replacement offering enhanced performance and Zone 2 certification. The 871TM-DR5NE18-H2 remains widely available through industrial automation suppliers and continues to serve in existing installations across manufacturing, process control, and hazardous area applications.\n\n\u003ch2\u003eKey Features of Allen Bradley 871TM-DR5NE18-H2\u003c\/h2\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIntrinsically Safe Design:\u003c\/strong\u003e Certified for use in explosive atmospheres with Zone 0\/1\/2 ratings\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e5 mm Sensing Range:\u003c\/strong\u003e Precise detection distance for close-proximity applications\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e18 mm Barrel Diameter:\u003c\/strong\u003e Standard M18 threading for universal mounting compatibility\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2-Wire Configuration:\u003c\/strong\u003e Simplified wiring with integrated power and signal on two conductors\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToughLink Cable:\u003c\/strong\u003e 2-meter 18 AWG cable provides enhanced durability in harsh industrial environments\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWide Voltage Range:\u003c\/strong\u003e Operates across 10 to 31.5 VDC for flexible system integration\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLow Current Draw:\u003c\/strong\u003e 2 to 25 mA load current minimizes power consumption\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical Specs of 871TM-DR5NE18-H2\u003c\/h2\u003e\n\n\u003ctable\u003e\n  \u003ctr\u003e\n    \u003ctd\u003e\u003cstrong\u003eModel Number\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd\u003e871TM-DR5NE18-H2\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd\u003e\u003cstrong\u003eSensor Type\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd\u003eInductive Proximity, Intrinsically Safe\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd\u003e\u003cstrong\u003eSensing Distance\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd\u003e5 mm\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd\u003e\u003cstrong\u003eHousing Diameter\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd\u003e18 mm\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd\u003e\u003cstrong\u003eInput Voltage\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd\u003e10 - 31.5 VDC\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd\u003e\u003cstrong\u003eLoad Current\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd\u003e2 - 25 mA\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd\u003e\u003cstrong\u003eWire Configuration\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd\u003e2-wire\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd\u003e\u003cstrong\u003eCable Type\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd\u003e2 m ToughLink cable (18 AWG)\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd\u003e\u003cstrong\u003eOutput Type\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd\u003eNormally open\/closed (configurable)\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd\u003e\u003cstrong\u003eHazardous Location Rating\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd\u003eIntrinsically Safe (Zone 0\/1\/2)\u003c\/td\u003e\n  \u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eApplications \/ Use Case\u003c\/h2\u003e\n\nThe Allen Bradley 871TM-DR5NE18-H2 serves critical detection functions in hazardous manufacturing environments where explosive gases, vapors, or dust present safety risks. Oil and gas facilities utilize this sensor for valve position monitoring, pipeline equipment detection, and process control in classified areas. Chemical processing plants deploy the 871TM-DR5NE18-H2 for reactor vessel monitoring, mixing equipment control, and automated batch processing where intrinsic safety certification is required. Pharmaceutical manufacturing operations rely on this sensor for sterile environment detection, filling line control, and packaging automation in explosive solvent atmospheres. Mining operations use the sensor for conveyor monitoring, material handling detection, and crusher equipment control in coal dust environments. Paint and coating facilities implement this proximity sensor for spray booth automation, conveyor tracking, and robotic application systems where flammable vapor concentrations demand intrinsically safe components. The 2-wire design simplifies installation in legacy control panels, while the ToughLink cable withstands exposure to hydraulic fluids, cutting oils, and harsh cleaning agents common in heavy industrial settings.\n\n\u003ch2\u003eRelated Resources\u003c\/h2\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/leadtime.ca\/\" target=\"_blank\"\u003eLeadTime.ca – Industrial Automation Components \u0026amp; Repair Services\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/leadtime.ca\/collections\/allen-bradley\" target=\"_blank\"\u003eView All Allen Bradley Products\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/leadtime.ca\/blogs\/learning-center\/examples-of-industrial-automation-control-systems\" target=\"_blank\"\u003eExamples of Industrial Automation and Control Systems\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/leadtime.ca\/products\/allen-bradley-1756-en2tr\" target=\"_blank\"\u003eAllen Bradley 1756-EN2TR EtherNet\/IP Module\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/leadtime.ca\/products\/allen-bradley-5094-ib16\" target=\"_blank\"\u003eAllen Bradley 5094-IB16 Flex 5000 Input Module\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Allen Bradley","offers":[{"title":"Default Title","offer_id":47870780571947,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0837\/4671\/7995\/files\/Leadtime_24431c31-3412-49a2-b260-3dbadf509a29.png?v=1723532257","url":"https:\/\/leadtime.ca\/products\/allen-bradley-871tm-dr5ne18-h2","provider":"LEADTIME","version":"1.0","type":"link"}
