This miniature float switch with an 8 mm switching tube is designed for industrial applications that require high material resistance and simple 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 pressure. The proven reed technology operates without continuous current and offers precise, durable level detection. Vertical installation is achieved via a robust G1 external thread, which allows stable, tight mounting from the outside, while the PVC connection cable ensures flexible integration into existing systems.
