OPCON 1141D-6501 Through-Beam Photoelectric Sensor

With a sensing range of up to 700 ft (213 m), the OPCON 1141D-6501 Through-Beam Photoelectric Sensor delivers long-range, non-contact object detection for industrial automation. As part of the 20 Series Heavy Duty, it employs a through-beam configuration in a right-angle housing with a LED light source for dependable sensing across conveyors, packaging lines, and material-handling equipment. It operates on 95–130 VAC RMS, with screw terminals and conduit entrance for robust wiring in harsh environments, and its enclosure is die-cast aluminum rated IP67 and IP69K. The compact package measures 5.7 × 3.28 × 4.25 in and weighs about 3.6 lb (1.63 kg); it supports an operating temperature range from -20°C to +55°C (-4°F to +131°F). Common industrial uses include conveyor and sortation systems, packaging machinery, assembly lines, and warehouse automation, where long-range part counting and machine sequencing are required. Common replacements include Eaton 1141D-6501, OPCON 1241D-6501, and OPCON 1420B-6501.
