Technical drawing

This miniature float switch with an 8 mm switch tube was developed for industrial applications where a compact design and high material resistance are crucial. The housing made of stainless steel 1.4571 and the float made of 1.4301 allow for use in demanding media and under increased pressure. The reliable reed technology operates without continuous current and ensures precise, long-lasting level detection. The electrical connection is made directly via an M12 connector, while vertical mounting in the combined M12x1 / G3/8 internal thread enables secure, tight installation in various container types.
