This miniature float switch with an 8 mm switching tube was developed for industrial applications requiring high material resistance and precise switching points. The housing made of stainless steel 1.4571 and the float made of 1.4301 enable use in demanding media and under increased pressure. The reliable reed technology operates current-free in standby mode and ensures long-lasting, low-maintenance level detection. Vertical mounting is achieved via a combined M12x1 / G3/8 internal thread solution, allowing for flexible and tight installation in various housing and container types.
