This miniature float switch with an 8 mm switching tube is designed for applications requiring a compact design and a robust, standardized electrical connection. The housing and float are made of resistant PP, making the sensor well-suited for water-based and mildly chemically contaminated media. The proven reed technology enables reliable, currentless level detection with minimal wear. Horizontal mounting via a G1 male thread allows for simple, tight external installation, while the DIN-43650 connector ensures a quick and secure electrical connection.
