Technical drawing

This standard float switch with a Ø12 mm switching tube is designed for industrial applications requiring reliable switching points and robust materials. The housing, made of stainless steel 1.4571, offers high resistance to corrosive media, while the POM float is ideally suited for clean, neutral fluids. The proven reed technology operates without continuous current and enables precise, durable level detection. Vertical installation is achieved via a stable D75 flange from the outside, while the standardized DIN-43650 connector enables quick and secure electrical integration.
