This miniature float switch with an 8 mm switching tube combines a compact design with a fast electrical connection via an M12 connector. The housing and float are made of resistant PVC and are therefore ideally suited for applications near water and slightly chemically contaminated media. The reliable reed technology operates without continuous current and ensures durable, precise level detection. Mounting is vertical via a G 3/8 male thread, allowing the sensor to be installed easily, safely, and tightly from the outside.
