Eaton 1391A-6501 Photoelectric Proximity Sensor

The Eaton Opcon 1391A-6501 Photoelectric Proximity Sensor is a non-contact object detector that uses emitted light to sense the presence or absence of a target, enabling reliable detection without physical contact. Identified by model 1391A-6501 within Eaton’s Opcon family, this sensor relies on optical sensing to determine when a beam is interrupted or reflected, supporting fast response and consistent detection across a range of surface textures and colors. Photoelectric proximity sensors are widely used in industrial automation to verify part presence on conveyors and production lines, monitor feeder operations, and trigger downstream equipment, all while avoiding wear typical of contact sensors. Because it detects targets via light, it is suitable for applications involving small, delicate parts or high-velocity lines where physical sensors might wear or cause damage. The 1391A-6501 designation identifies this specific unit within Eaton’s Opcon lineup of optical sensing solutions.
