This miniature float switch with an 8 mm switch tube was developed for applications requiring high mechanical resilience and robust external mounting. The housing made of stainless steel 1.4571 and the float made of 1.4301 enable reliable use in demanding media and under increased operating pressure. The proven reed technology operates without continuous current and offers precise, long-lasting level detection. The electrical connection is made via a standardized DIN 43650 connector, while vertical installation via a G1 external thread ensures secure, tight external mounting.
