This model uses a visible red sensing beam and features a right-angle, 18 mm cylindrical housing, which allows for simple integration into tight spaces or complex machine layouts. With a sensing range of up to 8 meters and a fast 1 ms response time, the 42EF-R2MNBT-F4 delivers reliable detection for both light and dark operate applications. Its 4-pin Micro QD connector ensures quick, secure installation and connection to control systems. The sensor is engineered with an IP67\/IP69K enclosure rating and NEMA 4X\/6P protection, making it suitable for harsh environments where moisture and debris resistance are critical. The RightSight platform is valued for its high visibility LED indicators, easy alignment, and robust performance in automation and manufacturing applications.\n\n\u003ch2\u003eKey Features of Allen Bradley 42EF-R2MNBT-F4\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eVisible red sensing beam for easy alignment\u003c\/li\u003e\n  \u003cli\u003eUp to 8 m sensing range (transmitted beam receiver type)\u003c\/li\u003e\n  \u003cli\u003eRight-angle 18 mm form factor for flexible installation\u003c\/li\u003e\n  \u003cli\u003e1 ms response time ideal for high-speed applications\u003c\/li\u003e\n  \u003cli\u003eLight\/dark operate modes for versatile detection\u003c\/li\u003e\n  \u003cli\u003e4-pin Micro QD connector simplifies wiring and maintenance\u003c\/li\u003e\n  \u003cli\u003eIP67 and IP69K environmental protection, NEMA 4X\/6P rugged enclosure\u003c\/li\u003e\n  \u003cli\u003eUltra-bright 360° LED status indicators for visibility during setup and operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical Specs of 42EF-R2MNBT-F4\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eSensing principle: Transmitted beam (receiver)\u003c\/li\u003e\n  \u003cli\u003eSensing range: 8 meters\u003c\/li\u003e\n  \u003cli\u003eSupply voltage: 10.8–30 VDC\u003c\/li\u003e\n  \u003cli\u003eCurrent draw: 15 mA\u003c\/li\u003e\n  \u003cli\u003eOutput: NPN, light\/dark operate\u003c\/li\u003e\n  \u003cli\u003eConnector: 4-pin DC M12 pigtail (Micro QD)\u003c\/li\u003e\n  \u003cli\u003eResponse time: 1 ms\u003c\/li\u003e\n  \u003cli\u003eEnclosure: 18 mm (diameter) right-angle housing\u003c\/li\u003e\n  \u003cli\u003eProtection: IP67, IP69K, NEMA 4X\/6P\u003c\/li\u003e\n  \u003cli\u003eDimensions: 27 mm (W) × 46.7 mm (H) × 34.5 mm (L)\u003c\/li\u003e\n  \u003cli\u003eWeight: ~0.001 lb\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eApplications \/ Use Case\u003c\/h2\u003e\nThe Allen Bradley 42EF-R2MNBT-F4 is widely used for reliable object detection in automated assembly lines, materials handling, and packaging operations. Its compact right-angle design allows mounting in constrained areas on conveyors, robotic cells, or machinery where space is limited but performance requirements are high. The 8 meter sensing range, combined with a high immunity to electrical noise and environmental contaminants, makes it suitable for detecting products, monitoring presence or absence, and controlling gates or ejectors in production environments. The IP67\/IP69K enclosure ensures long-term durability in food and beverage, automotive, and general manufacturing facilities. Maintenance crews appreciate the sensor's visible status LEDs for quick troubleshooting, reducing downtime and supporting efficient operations.\n\n\u003ch2\u003eRelated Resources\u003c\/h2\u003e\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-5094-ib16\" target=\"_blank\"\u003eAllen Bradley 5094-IB16 Flex 5000 Input Module\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/leadtime.ca\/products\/allen-bradley-1769-of8-c\" target=\"_blank\"\u003eAllen Bradley 1769-OF8 Analog Output Module\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cbr\u003e","brand":"Allen Bradley","offers":[{"title":"Default Title","offer_id":47870764843307,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0837\/4671\/7995\/files\/Leadtime_d991f344-9316-4f26-b6ef-ac4d878a735d.png?v=1723532685","url":"https:\/\/leadtime.ca\/products\/allen-bradley-42ef-r2mnbt-f4","provider":"LEADTIME","version":"1.0","type":"link"}
