This miniature float switch with an 8 mm switching tube is designed for applications where high temperature resistance and media resistance are crucial. The housing and float are made of PVDF, a particularly chemical-resistant material that is ideal for aggressive liquids and elevated temperatures. The reliable reed technology operates without continuous current and offers precise, long-lasting level detection. Vertical mounting via a G 3/8 internal thread enables secure and tight installation, while the flexible silicone cable remains reliable even with large temperature fluctuations.
