Technical drawing

This standard float switch with a Ø12 mm switch tube is designed 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 operate reliably in aggressive or pressurized liquids. The proven reed technology operates without continuous current and enables durable and precise level detection. Vertical installation is performed externally via a G2 thread.
