Technical drawing

This standard float switch with a Ø12 mm switch tube is designed for demanding applications where high pressure resistance and media-resistant materials are required. The robust housing made of stainless steel 2.0321 in combination with a float made of 1.4571 allows for reliable use in aqueous, slightly chemically aggressive, and pressure-loaded media. The precise reed technology operates without continuous current and ensures long-lasting, low-maintenance level detection. Vertical installation is performed via a D75 flange from the outside, while the standardized DIN 43650 connector enables quick and secure electrical connection.
