This standard float switch with a Ø12 mm switch tube is suitable for industrial applications where corrosion-resistant materials and increased operating pressures are required. The housing and float are made entirely of stainless steel 1.4571, allowing the sensor to be reliably used in pressurized or aggressive liquids. The proven reed technology operates without continuous current and enables precise and durable level detection. Vertical installation is carried out from the inside via a G3/8 thread in combination with a PVC connection cable.
