This standard float switch with a Ø12 mm switching tube is suitable for applications requiring robust external mounting and reliable level signals. The stainless steel 2.0321 housing offers high stability and corrosion resistance, while the POM float is ideal for clean, neutral liquids. The precise reed technology operates without continuous current and enables durable, low-interference level detection. Vertical installation is carried out directly via the housing from the outside, ensuring a secure, tight integration into a wide variety of tanks and systems.
