Compact Photoelectric Liquid Level Sensor

This compact photoelectric liquid-level sensor is made of durable plastic and measures approximately 45 x 20 x 12 mm (L x W x H), with a minimal weight suitable for integration into small appliances. It operates on the principle of non-contact optical detection, using an infrared LED and phototransistor to sense liquid presence at the surface without submersion or physical contact. Designed for horizontal mounting directly at the target liquid surface, it features built-in mounting tabs and a sleek black rectangular housing for secure, space-efficient installation. The sensor comes pre-wired with a fixed-length cable terminating in a standard white connector — enabling plug-and-play integration even in confined spaces such as ice maker reservoirs or pet water dispensers. Ideal for applications requiring hygienic, maintenance-free level monitoring including ice generators, beverage dispensers, water coolers, and automated pet hydration systems.
