Horizontal-Mount Photoelectric Sensor

This plastic-housed photoelectric liquid-level sensor is engineered for precise surface-level detection in compact fluid systems. Dimensions are approximately 45 mm long, 20 mm wide, and 12 mm high, with negligible weight. It functions by detecting changes in light transmission at the liquid surface — activated only when liquid covers the optical window. The unit mounts horizontally with its sensing face aligned parallel to the liquid surface, secured via two integrated plastic tabs. No alignment tools or brackets are required. A pre-wired lead terminates in a white connector compatible with common 3.96 mm pitch headers. Widely adopted in ice-making modules, tabletop beverage dispensers, under-counter water coolers, and smart pet fountains — wherever reliable, low-maintenance fill-level control is needed without compromising enclosure integrity.
