Non-Touch Photoelectric Level Sensor

This photoelectric liquid-level sensor is constructed from robust plastic and features a compact black rectangular housing measuring roughly 45 x 20 x 12 mm. Its core function relies on optical beam interruption: when liquid reaches the sensing plane, it refracts the infrared beam between emitter and receiver, triggering a reliable digital output. The sensor is designed exclusively for horizontal surface-mount installation — no tank penetration, no moving parts, no calibration needed. Mounting tabs are integrated into the housing for tool-free, stable positioning. A pre-attached cable ends in a white connector, supporting quick connection to control boards in constrained environments. Commonly deployed in ice-making units, self-service drink dispensers, compact water coolers, and automatic pet waterers where hygiene, longevity, and ease of service are essential.
