This miniature float switch with an 8 mm switch tube is ideal for compact applications where chemical resistance and a small footprint are required. With its housing and float made of PP, the sensor is optimally suited for water-based and slightly aggressive media. The proven reed technology operates without continuous current, enabling precise, long-lasting level detection. Vertical mounting via a G 3/8 internal thread offers a secure, tight installation and allows for easy integration into various tank and system solutions.
