This standard float switch with a Ø12 mm switch tube is designed for demanding industrial applications where high pressure resistance and corrosion-resistant materials are required. The housing and float are made entirely of stainless steel 1.4571, allowing the sensor to be reliably used in aggressive and mechanically stressed liquids. The precisely operating reed technology provides durable, low-interference level detection without continuous current. Vertical mounting is achieved via a standardized DIN 2527 Type B flange (DN50, PN16), which enables stable, leak-proof external installation.
