This standard float switch with a Ø12 mm switch tube is designed for use in industrial systems where corrosion-resistant materials and increased mechanical load capacity are required. The housing and float are made entirely of stainless steel 1.4571, allowing the sensor to be reliably used in demanding liquids and under increased operating pressure. The precise reed technology operates without continuous current and enables durable, low-maintenance level detection. Vertical installation is carried out via a standardized DIN-2527 Type B flange (DN65, PN16), which ensures secure and tight external mounting.
